Design and Simulation of Wireless Sensor Network Topologies Using the ZigBee Standard

ZigBee is one of today's most useful technologies in the wireless sensor network industry. ZigBee, which is a new standard for wireless communication [14], is based on the IEEE 802.15.4standard announced in 2003 by the IEEE [15, 16]. ZigBee is established on powerful radio (physical layer) and MAC (Medium Access Control) layers defined by the IEEE 802.15.4 standard. It utilizes a standard CSMA/CA media access mechanism and supports star, tree and mesh topologies. IEEE 802.15.4 defines three license-free frequency bands. The first band uses the 2.4 GHz frequency band, i.e., the ISM (Industrial Scientific and Medical) band, and has 16 channels. The second band uses the 902-928 MHz frequency band with 10 channels. The other uses the 868-870 MHz frequency band with only one channel. The capacities of these frequency bands are 250 kb/s, 40 kb/s and 20 kb/s, respectively [15,17,18]. ZigBee deals with transferring certain amounts of data between devices used in personal area networks, measurements with networks, detection, monitoring and checking the applications. However, it is not suitable for large-size file transfers like Wi-Fi or Bluetooth. ZigBee is differentiated from Wi-Fi or Bluetooth in terms of communication approach between multiple devices, and works over simple networks with less power consumption and cost, also providing communication with lower bandwidth demands. In Table 1, a comparison of the features of ZigBee and some other wireless technologies is shown [15, 19]. As understood from the table, although the battery life of Bluetooth is 1-7 days, ZigBee’s battery life is 100-1000 days. In addition, while Wi-Fi’s fields of success are usually speed and flexibility, it can be said that ZigBee’s success rests in durability, cost and power consumption.

Enhanced Simulation Model of ZigBee Wireless Sensor Network

Enhanced Simulation Model of ZigBee Wireless Sensor Network

OPNET has been used to design tree self-organizing multi-hop network model based on IEEE 802.15.4 protocol, and the network formation time, data frame transmission performance, throughput, failure and recovery of equipment are simulated [1]. The medium access control (MAC) layer was optimized and designed, and the performance of a sensor network was analyzed for the MAC layer of different competition mechanisms [2,3]. The ZigBee network simulation system based on OPNET adopted ZigBee models of OPNET [4,5], which had disadvantages of difficulty in modeling, overhead, network delay, poor scalability, unguaranteed network access to all nodes, authenticity of communication radius, and other issues [6]. It is difficult to be applied in practical application areas which have high performance requirements, such as high reliability and less network delay. In addition, failures and recoveries of nodes cannot be simulated according to needs of tests, when performing a large-scale sensor network test by using ZigBee models of OPNET. When interval of frame-generating is small, and length of information has large increase, some nodes will appear continuous automatic failures or abnormal simulation.

Examine the Performance of different Topologies using Opnet 14 5 in ZigBee Sensor Network

Wireless sensor networks (WSN) consists of light-weight, low power and small size sensor nodes. They have capability to monitor, compute and connect wirelessly [1]. Zigbee is a wireless personal area network based on IEEE 802.15.4 wireless protocol. Zigbee network defined first in 2004 and released in 2006. The second stack of the Zigbee network was defined as Zigbee 2006. It provides short distance communication with low complexity, low data rate and low power consumption. It is a two way technology which pointed to Wireless Sensor Network (WSN) [2]. Furthermore, it has several advantages such as self organization, smaller size of protocol stacks, and larger addressing space. Most commonly Zigbee also used in the medical field for patient monitoring or health and added together with self-care and self-management technologies can enhance their health outcomes [3]. The main aim of this technology is remote control and sensor applications, which is appropriate to operate in ruthless radio environments and isolated locations.The IEEE 802.15.4 protocol defines MAC and PHY layers for personal area network (PAN) [4]. The medium access control (MAC) layer send data frames over radios channels with specified modulation and spreading techniques. It enables the transmission of MAC frames through the use of the physical channel. The MAC layer of IEEE 802.15.4 standards operates in two modes, they are beacon enabled and non-beacon enabled mode. In beacon enabled mode, beacon messages are transmitted periodically for network organization and management. Beacon enabled are synchronized and allows the mode to operate on slotted Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) mechanism. In non-beacon mode nodes are not synchronized, because periodic beacon transmissions are absent. Therefore, this mode supported to unslotted CSMA/CA mechanism [5]. The physical layer is defined by IEEE 802.15.4 standard. The physical layer is responsible for providing data transmission service [6]. The physical layer

Comparative Evaluation of Three Wireless Sensor Network Transceivers in a High Radiation Environment

Comparative Evaluation of Three Wireless Sensor Network Transceivers in a High Radiation Environment

Taking Fukushima accident as an example, in March 2012, the level of radiation is estimated to up to 73 Sv/h inside the containment of No.2 reactor [9], and Feb. 2017, the level has shot up to 530 Sv/h [10]. Such high level of radiation can, no doubt, cause severe damage to wireless transceivers and networks if no precautions are taken. Before any protection measures can be taken, it is necessary to investigate how different wireless devices and network components react to radiation under similar radiation conditions. Unfortunately, there are only limited resources available on radiation responses of industrial wireless devices and networks in the literature. To fill this gap, the characteristics of commonly used industrial wireless devices and networks are studied. The results of this study provides a scientific basis in the selection of suitable wireless technologies and network devices in such applications. Based on those studies and analysis, six industrial wireless nodes built with commercial off-the-shelf (COTS) components, CC2530 (2.4 GHz ZigBee standard), CC2520 (2.4 GHz WirelessHART standard), CC2530 (2.4 GHz ISA100.11a standard), are chosen to undergo irradiation tests in a gamma radiation environment. Since these are destructive tests, a group of diversified wireless devices are therefore built using different industrial wireless networks for the radiation tests. A total dose test is performed to measure the behaviors of the developed wireless devices and networks by directly exposing them to 60Co gamma irradiator at The Ohio State University Nuclear Reactor Laboratory (OSU-NRL) under a high dose rate (20 K Rad/h). The results of this test will provide guidelines to design wireless monitoring instruments for using in high level radiation environments. They serve as important references to assist other researchers and engineers to design and manufacture radiation-hardened (rad-hardened) monitoring system by using COTS components.

ABSTRACT: Zigbee wireless communication technology is a kind of newly arisen wireless network technology;

Sometimes when trying to discover Zigbee, there may occur an error like - 'Could not find any device in port COM6 >For input string: "ERROR" or error initializing device parameter = connection timeout or could not find device parameter' then the error may be because of the incorrect baud rate. For this, connect the modem using FTDI cable to the PC, open XCTU, select the COM port and multiple baud rates like 9600, 115200, 57600 then search for the radio module and possibly there the radio module can be found. But if not found, then open XCTU legacy (old version), select the possible baud rate and in the modem configuration window select the correct modem firmware/ function set, then enable „always update firmware‟ and select write. After that, when the info box (action required) appears, then reset the Zigbee by connecting RST to GND or simply unseat the Zigbee and again place on seat. Now info box will disappear. It will then re-flash the radio modules automatically.
