Development of Efficient Multi Hop Protocols for Wireless Body Area Network (WBAN)

Development of Efficient Multi Hop Protocols for Wireless Body Area Network (WBAN)

A convention like store and forward component is proposed in [11] however they integrate transmit power adaption scheme in the strong instance of WBAN multi-hop. To monitor energy consumption for transmission, each node must know its neighbor. Data transmission is done with stable link quality and minimal power consumption. A similar transmission power control scheme is proposed by authors in [12] which is a packet forwarding scheme with minimal power consumption in body area sensor network. By incorporating automatic repeat request (ARR) an increase in network throughput with minimal power consumption is achieved as lower power is required to retransmit the drop packets. The literatures in [13]and [14] analyzed the amount of data delay as they operate in a heterogeneous platform in WBAN comparative analysis for different medium access control (MAC) protocols for WBAN.

Energy Efficient and Priority Based MAC Protocols for Wireless Body Area Network: A Survey

1168 | P a g e problems. From the overall analysis, nodes should extremely save their energy usage as much as possible. In addition, most of the data generated by the sensor nodes areredundant, it also causes a significant amount of energysurplus. Time critical data gathered from many WBANs are stored in the form of packets. Many researches have been focused some techniques to reduce the latency issues and few proposed scheduling methods to prioritize the critical packets in a queue. Since, the priority based scheduling, extremely energy efficient and intelligent packet reservation MAC protocols are necessary to eliminate the delay and energy issues. Also, a WBAN positioned on one patient’s body may be connected with other patient in different data rates and power usage. However, this network must have to ensure consistent data transfer using specific set of MAC protocols to improve the data exchange, interact with other applications. In future, maintenance of data over the network fully depends on the prediction of challenges in QoS.

Abstract - Wireless sensor network (WSN) is the promising technology that’s being employed for many applications in multiple fields. Advancements of WSN have made it eventually possible to deploy several fields (e.g. battle, environment monitoring, surveillance, industry, health, etc.) However, existing approaches experience the severe security threats in the field of WSNs particularly in the wireless body area networks (WBANs). These security threats are observed at all layers. However, Medium Access Control (MAC) sub- layer faces more challenges as collate with other layers because of radio that consumes more energy resources.

Efficient authenticated key exchange protocols for wireless body area networks

Efficient authenticated key exchange protocols for wireless body area networks

In this paper, we propose two authenticated key exchange protocols that are suitable for WBANs. The two schemes are proved to be secure in BAN logic model. The perfor- mance analysis of them are also given. The analysis results show that the proposed protocols achieve the expecta- tive goals and possess several advantages: they provide favorable security performance and are capable of resist- ing sundry common attacks to guarantee communication security; the participants accomplish authentication and generate session key by five or six steps without tangle- some cryptographic operation; on account of majority security protocols utilizing timestamp to guarantee the freshness of messages, the participants must keep clock synchronization which is rather untoward and costly. However, the proposed protocols adopt random number instead of timestamp, reducing the complexity of the net- work as well as decreasing the cost. The performance analysis shows that the protocols have superior running time performance, less memory costs, and so forth. How to design more and better protocols for WBANs is the next target of further research.

A Survey on Wireless Body Area Network

Sensing and monitory digital devices that an individual can wear on the body and are based on wireless technology are already in existence. There can be in the form of smart cloth or bandages which allows the continuous monitoring of blood glucose levels, blood pressure and other biometric data Wearable biosensors are the non-obstructive devices that helps to overcome the limitations of ambulatory technology and also provide a fast and energetic response to the need of monitoring patients over a long period of time and it works even in a distant area. We will like to start with the already existing sensors, basically there are two types of sensors which are the wearable sensors and the implanted sensor both type of sensor biological device which as a physiochemical transducer used to produce an electronic signal which is equal to a single analysis which is transmitted a to a detector. These sensors are been designs with respect to the fact that the outcome must be improved while the cost and bulkiness of the sensor are reduce. The real world physiological data gotten from the sensor is being sent wirelessly to the internet which is then forwarded to the doctor so this helps in the optimization of the well being of the patient’s wellness by making the medical progress better and easier in the collection and analysis of the patient data.

Energy Harvested IEEE802.15.4 Wireless Body Area Network

Energy Harvested IEEE802.15.4 Wireless Body Area Network

Different from [16], Merrett et. al, [6] consider the effect on harvestable power of generator location (five locations on the body, such as: elbow, wrist, waist, knee and ankle), hu- man activities and take into account the effect of generator orientation and its relation with the other parameters. Au- thors also propose 2-DOF (Degree of Free) generators in or- der to examine whether these 2-DOF generators do increase the output power of energy harvested as well as do improve a generator’s tolerance to orientation variation and different activities. Experiments and substantial analysis show that 2-DOF generators do not provide significantly greater out- put power. However, factors of rotation and misalignment which have significantly affected energy harvested, can be reduced using the 2-DOF generator.

UWB Technology for Wireless Body Area Network

UWB Technology for Wireless Body Area Network

WBAN is a network formed by intelligent, small size, low-power sensor which are attached or implanted into a human body [1]. This monitors the body functions and changes in surrounding environment and gives a real time feedback to doctor or patients, and obtained information are stored in a database. This type of technology use Wireless Medical Telemetry System and Medical Implant Communication System to provide efficient healthcare facility and to reduce the load at hospitals. It is a difficult task to connect all the devices and sensors through wires, as it causes complication. In order to avoid that, WBAN technology has been used. WBAN provides easier, low cost and real time response. The IEEE wireless body area network standard (IEEE 804.15.6 TG6) [4] had been formed in order to develop and standardize the Physical Layer (PHY) and Medium Access Control (MAC) protocols for short range, low power and highly reliable wireless communication schemes to operate in, on and around the human body [7]. Due to new improvement in sensor technology, sensed signal by the sensors increased drastically. Hence to transmit large amount of data a WBAN require a high capacity wireless link that should support data rates from a few bps to several Mbps. To achieve high capacity wireless link WBAN use a UWB technology.

Network Lifetime Enhancement for Wireless Body Area Networks

Network Lifetime Enhancement for Wireless Body Area Networks

A WBAN will consist of a number of tiny sensor nodes and gateway node which are small intelligent devices. The gateway node is used to connect external database server. The gateway node could connect the sensor node to a range of telecommunication networks. These communication networks could be a standard telephone network, mobile phone network, a dedicated medical center/ hospital network or using public Wireless Local Area Network (WLAN) hotspots [1]. A WBAN can also take advantage of deployed mobile data networks such as 3G/4G data network to transmit patient data. A WBAN could allow a user to store its collected data on his/her Personal Digital Assistant (PDA) or iPod or any other portable devices. This data is then transfer to a suitable computer or a medical server. Fig. 1 shows the General Wireless Body Area Network Architecture [2].

Design Of Dynamic Energy Efficient Multi-Hop Protocols For Wireless Body Area Network

Design Of Dynamic Energy Efficient Multi-Hop Protocols For Wireless Body Area Network

In this paper, we suggest a process for WBAN routing data. The proposed scheme uses a cost function to select a suitable sinking route. By introducing new route costs based on residual resources like required hops, link quality, and distance for selecting the best next-hop node for transmitting the packets successfully. The simulation results reported a reduction in consumption of energy among two nodes decreased a lot with minimal delay and higher throughput. The proposed EALER-W routing protocol maintains a longer network lifetime as related to the traditional SIMPLE protocol. It often demonstrates that the proposed routing system increases the stability in the network and the number of packets transmitted to the sink.

A Study on Traffic Adaptive MAC Protocols for Wireless Body Area Network

A Study on Traffic Adaptive MAC Protocols for Wireless Body Area Network

BSN-MAC is designed to be an adaptive MAC protocol. By exploiting feedback information from distributed sensors in the network, BSN-MAC adjusts protocol parameters dynamically to achieve best energy conservation on energy critical sensors. They introduced two tradeoffs in BSN-MAC design. The first is between the energy of coordinator (unconstrained) and the life of energy-critical sensors nodes. The second is between the sensor data report delay and the life time of energy-critical sensors nodes.Once the node powers up its radio and gets synchronized, depending on the beacon information and buffered data size, it either sends out a data transmission request (REQ) packet followed by part of the sensory data or sends out the sensory data directly. After the node synchronizes with the coordinator, by decoding the beacon frame, the node learns the length of the beacon interval and understands whether it can transmit its data during a single beacon interval. If yes, it will start transmitting its data directly. Otherwise, the node sends out a REQ packet first to ask the coordinator to change the beacon interval. The REQ packet includes the PMAC of the sensor, which is used by the network coordinator to determine the priority when multiple REQs are received.

Patient Health Monitoring Using Wireless Body Area Network

Patient Health Monitoring Using Wireless Body Area Network

One of the many applications of Wireless Body Area Network is in medial environment where conditions of patients are continuously monitored in real time. In order to deploy a complete wireless senor network in healthcare systems, wireless monitoring of physiological data from a large number of patients is one of the current needs. A wireless network containing small interdependent sensor nodes is called WSN (wireless sensor network). Such a wireless sensor network system is very suitable to be used in hospital environments to reduce human errors, to reduce health care cost, to provide more time to health professionals to deal with other important issues.Physiological data are to be measured and monitored with the help of this proposed system. The data that is measured by these sensor nodes is sent to a base station using RF (radio frequency) communication. The communication between the nodes and the base station can be a single hop communication or it can be a multi hop communication depending on the remoteness of the sensor node. The base station also controls the whole network. On each sensor node there are various hardware components. Some of those are Microcontroller, Sensor or Transducer, Radio Frequency Transceiver, Battery or some other power source. Several other components are used for signal processing purpose to bring the sensor output signal in proper form and for proper power supply required for main components. The components required for this purpose are voltage regulators, Amplifiers, resistors and capacitors. The main purpose of this system is to achieve the communication between different sensor nodes and a single receiver simultaneously.

A Review On Mac Protocols In Wireless Body Area Networks

A Review On Mac Protocols In Wireless Body Area Networks

Several attributes need to be counted for the intention of an energy-efficient MAC protocol for a WBAN. One of the elementary attribute is energy efficiency. WBAN devices are run by a battery requires stringent restriction on the employment of energy resources. To achieve this goal, design of energy-aware communication protocol is affected. Energy-efficiency can be increased by minimizing the energy wasted. WBANs are intended to hold up life saving critical applications. Hence reliability, safety and security are considered important metrics besides energy efficiency. The QoS is also an important factor of a good MAC protocol. Other parameters of importance include scalability, adaptability to changes in network topology, throughput, jitter, latency and bandwidth usage. In case of medical applications, latency should be less than 125ms for QoS. In summary, the attributes of a good MAC in WBAN include energy-efficiency, reliability, heterogeneous traffic, safety and security in addition to QoS.

Wireless Body Area Network Technology

Wireless Body Area Network Technology

A typical BAN or BSN requires vital sign monitoring sensors, motion detectors (through accelerometers) to help identify the location of the monitored individual and some form of communication, to transmit vital sign and motion readings to medical practitioners or care givers. A typical body area network kit will consist of sensors, a Processor, a transceiverand a battery. Physiological sensors, such as ECG and SpO2 sensors, have been developed. Other sensors such as a blood pressure sensor, EEG sensor and a PDA for BSN interface are under development. At the hardware level, body sensors must be small, thin, non-invasive, wireless-enabled, and must be able to operate at a very low power level. From the communications perspective, it is imperative to design appropriate medium access control (MAC) protocols to ensure higher network capacity, energy efficiency, and adequate quality of service (QoS).

Energy Efficient Routing Protocols in Wireless Sensor Network

Energy Efficient Routing Protocols in Wireless Sensor Network

Wireless Sensor Networks (WSNs) are self-organizing, infrastructure less and multi-hop packet forwarding networks. There is no concept of fixed base station. So, each node in the network acts as a router to forward the packets to the next node. Wireless networks are capable of handling of topology changes and malfunctions in nodes. It is fixed through network reconfiguration. For instance, if the node leaves the network and causes link breakages, affected nodes can request new routes and problem will be solved. This will slightly increase the delay, but the network will still be operational. It is the technology aimed to provide broadband wireless data access over long distances. This technology provides basic Internet Protocol (IP) connectivity to the user. The variety of applications used in IP networks has increased tremendously in the recent years. Various multimedia applications along with the common email, file transfer and web browsing applications are becoming increasingly popular. These applications send large audio and video streams with variable bandwidth and delay requirements. On the other hand, remote monitoring of critical services such as E-commerce and banking applications which do not need strict bandwidth guarantees due to the good nature of the data transfer. Instead, these applications require reliable and prompt packet routing. The presence
