DESIGN AND IMPLEMENTATION OF SERVICE ORIENTED ARCHITECTURE

All the messages shown in the above figure are sent using SOAP. (SOAP at one time stood for Simple Object Access Protocol. Now, the letters in the acronym have no particular meaning .) SOAP essentially provides the envelope for sending the Web Services messages. SOAP generally uses HTTP , but other means of connection may be used. HTTP is the familiar connection we all use for the Internet. In fact, it is the pervasiveness of HTTP connections that will help drive the adoption of Web Services. More on SOAP and Messaging.

Knowledge based Replica Management in Data Grid Computation

Knowledge based Replica Management in Data Grid Computation

Replica Manager. Its purpose is to manage all replica management related functions. For the implementation of replica manager we purposes SOAP (Simple Object Access Protocol) based system that replicate the required information gained from knowledgebase. SOAP is a lightweight protocol for exchange of information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts: an envelop that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined data types, and a convention for representing Remote Procedure Calls and responses.

Web Services: Architectural Styles and Design Considerations for REST API

Web Services: Architectural Styles and Design Considerations for REST API

Web Services have been used since many years as an interface between applications. Web Services such as Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are extremely useful in data transfer and comparatively faster. Creating a Web Service saves the hassle for all developers as the tedious work such as building the database, automating the system and even performing SQL or other database queries is taken away. With such hassles out of the way they can just jump into building what they intended to and leverage this data using our proposed web service.

Design and feasibility of mobile peer to peer payment systems

Design and feasibility of mobile peer to peer payment systems

. All of these message data con- tainers are simple - they do not encapsulate others and are only composed from a small set of primitives, integer, character string and byte string types, or types that are easily transformed to such a primitive, such as coin rep- resentations and elliptic curve points. Case classes cannot be sent over the client-bank and client-client network connections as-is; a method to serialize and deserialize these messages is necessary. We used the SBinary library to accomplish just that; the data containers are serialized to a binary format. This is accomplished by assigning a small integer flag for each message type in the protocol. Then all of the primitive types of which the messages are composed of are serialized to byte data representing these primitives, and appended to the flag. Upon deserialization, the flag is read to determine which format must be deserialized, and the bytes corresponding to their primitives are read into the appropriate data fields. An example of a binary representation of a protocol message is given in figure 9 . An overview of all the message types that exist in the E ssential protocol are found in table 5 .

XML as a format of expression of Object-Oriented Petri Nets

XML as a format of expression of Object-Oriented Petri Nets

The basic conception of PN is quite simple. A PN is composed of two types of node – places and transi- tions – and of directed arcs. Arcs interconnect places and transitions. Places can contain tokens, which can be distinguishable according to the type of PN and whose number differs depending on transition events. This structure and semantics is common to all PN types and levels. There are differences especially as regards the understanding of places and tokens, the character of transition functions, and the structure and modularity of the whole net. Taking into account the limited scope of this article, it is not possible to describe the entire PN development branch, from the basic types to OOPN. Therefore, we will focus solely on OOPN, and in particular on their features that have not been described by the structured PNML language.

Concerning energy potency, add [22] given associate degree expedient routing protocol for minimizing the energy consumption of the nodes composing a set wireless sensing element network. Centered on a multi-hop chain topology, the projected algorithmic rule takes into consideration 2 key metrics to pick the candidate set: the space of the sensing element nodes to the sink and also the residual energy of every node. The candidate-coordination section is dole out following associate degree ACK strategy: every candidate with success receiving the data-packet replies associate degree ACK to the sender once a given amount determined by its priority. This operation is performed given that no alternative ACK from a higher-priority node has been overheard. once the ACK reply is completed, the data packet is forwarded. The projected protocol was tested in each simulation and realistic test-benches, showing higher performance, in terms of energy consumption, than GeRaF [13] and a MTE (Minimum Transmission Energy) protocol. add [23] conjointly focuses on up energy potency however from a special perspective, by victimization the pismire colony conversation and geographic forwarding.

61 Hack Into Your Friends Computer [ PUNISHER ] pdf

The next step was to obtain a password. The owners of the terminal to which the hacker had access did not know their ID; they had no need to know it because it was programmed into the terminal and sent automatically. The hacker could have put micro ’back-to-front’ across the line and sent a ENQ to see if an ID would be sent back. Instead he tried something less obvious. The terminal was known to be programmable, provided one knew how and had the right type of keyboard. Engineers belonging to the service had been seen doing just that. How could the hacker acquire ’engineer’ status? He produced the following hypothesis: the keyboard used by the service’s customers was a simple affair, lacking many of the obvious keys used by normal terminals; the terminal itself was manufactured by the same company that produced a range of editing terminals for viewdata operators and publishers. Perhaps if one obtained a manual for the editing terminal, important clues might appear. A suitable photocopy was obtained and, lo and behold, there were instructions for altering terminal IDs, setting auto-diallers and so on.

Partial Contention Free Random access Protocol for M2M communications in LTE Networks

Partial Contention Free Random access Protocol for M2M communications in LTE Networks

sent the Random Access Response (RAR) within time window of 5 subframes [13]. Then, the eNodeB should receive the corresponding message 3 within a time window of one frame; otherwise it will know that there is a collision in that preamble. Consequently, the system needs a time of more than one frame to detect the collision. Since the operation of the DQAL is based on broadcasting information about the detection status of preambles, two frames time interval is selected as a collision resolution interval as shown in Fig.2. Thus, the DQAL protocol is virtually see the LTE frame periodicity as a number of consecutive CRIs. 2.2. Preamble Status Detection

MFQMAC  A Faired and QoS Assured MAC protocol for Multihop Adhoc Network

MFQMAC A Faired and QoS Assured MAC protocol for Multihop Adhoc Network

Extensive simulation have been done using ns2.33 simulator [20] in order to evaluate the performance of the proposed MFQMAC protocol. The protocol has also been compared with other schemes such as DCF, AEDCF & FQA regarding QoS provisioning and per-flow fairness under various traffic scenarios. The Mobile Adhoc Networks were created with 6, 15, 21,25 nodes respectively confined to an area of 1000m by 1000m. The transmission range of a node was assumed as 250m. Initially, the nodes were randomly placed in the area. Each node remains stationary for a pause time, the duration of which follows an exponential distribution with a mean of 10 seconds. The node then chooses a random point in the area as its destination and starts to move towards it. The speed of the movement follows a uniform distribution between 0 and the maximal speed v max . Network mobility is varied when we

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

Because of node deployment, on the human body, they have to consume less power so that it does not harm them. Nevertheless, there can quiet be substantial signal attenuation, because all organs of a person possess particular dielectric constant and signal absorption happens accordingly. We present a new routing protocol for WBANs in this section. The limited number of nodes in the WBANs enables the routing protocols to be relaxed. Taking into account routing restrictions, we increase the network stability time and network performance.

A Survey Paper on Wireless Access Protocol

A Survey Paper on Wireless Access Protocol

CDMA is a spread-spectrum technology that spreads a signal across a large spectrum range based on the code sequence associated with the mobile terminal. All mobile terminals in a cell share the same spectrum, and the mix of all signals manifests itself as noise. Base stations are aware of the code sequences of all the mobile terminals in the area, and are able to decode the spread-spectrum signals. 7.1.2. Application Layer Security: WAP achieves application layer security by taking advantage of WTLS (Wireless Transport Layer Security), access control features in WML and WML Script, and TLS (Transport Layer Security) / SSL (Secure Sockets Layer). NTT DoCoMo’s I-Mode service does not offer any application layer security or HTTPS (HTTP over TLS/SSL) at this time.

Embedded Web Server for Monitoring and Controlling of system Using ARM Processor

Embedded Web Server for Monitoring and Controlling of system Using ARM Processor

HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. As soon as a Web user opens their Web browser, the user is indirectly making use of HTTP. HTTP is an application protocol that runs on top of the TCP/IP suite of protocols (the foundation protocols for the Internet).HTTP is a simple protocol that is based on a TCP/IP protocol stack (Fig.3). HTTP uses TCP. TCP is a relative complex and high- quality protocol to transfer data by the subordinate IP protocol. TCP itself always guarantees a Safeguarded connection between two communication partners based on an extensive three way handshake procedure. As a result the data transfer via HTTP is always protected.

Visuomotor strategies for object approach and aversion in Drosophila melanogaster

Visuomotor strategies for object approach and aversion in Drosophila melanogaster

±45 deg (Fig. 1A,B). Confirming the results of a previous study that used solid black bars on a uniform background (Maimon et al., 2008), on average flies steered toward a tall textured bar and avoided a short bar moving across a static random background (Fig. 1C). Averaging across trials masks the dynamics of the behavior for fixation and aversion. The spikes in Δ WBA – which have been referred to as ‘ wing hitches ’ (Heide and Götz, 1996) or ‘ torque spikes ’ by direct torque measurements in tethered flight (Heisenberg and Wolf, 1979) – indicate attempted body saccades. Δ WBA spikes were readily observed within single trials that were generally oriented toward the tall bar and away from the short bar located 45 deg from the visual midline (Fig. 1C; Fig. S1). Δ WBA spikes were superimposed upon a shift in mean Δ WBA toward the tall bar and away from the short bar (Fig. 1C; Fig. S1), consistent with prior work (Maimon et al., 2008). The raw traces from multiple flies (Fig. 1C) would seem to suggest not only that the valence of Δ WBA spikes switches with bar size but also that the short bar might elicit Δ WBA spikes with distinct dynamics. To explore the distribution of saccadic steering spikes across the full visual azimuth, and how saccade dynamics vary with object size, we used an experimental method in which a bar was randomly jittered at each of 24 azimuthal positions (Aptekar et al., 2012, 2014). We randomly shuffled trials for bar vertical heights of 94 deg (tall bar, full height of arena), 56 deg, 30 deg and 15 deg (short bar). We measured the amplitude of individual Δ WBA spikes binned at 24 azimuthal position (Fig. 1D). This analysis revealed a switch of sign and increased amplitude in Δ WBA spikes as the bar height decreased (Fig. 1D,E). The overall Δ WBA spike rate was similar across object height (Fig. 1E). However, the Δ WBA spike amplitude in the rigid tether must be interpreted with caution as different tonic Δ WBA levels between short and tall bars could bias Δ WBA spike amplitude.

EMOSY: An SNMP protocol object fenerator for the protocol independent MIB

EMOSY: An SNMP protocol object fenerator for the protocol independent MIB

[6] or the Guidelines for the Definition of Man- aged Objects (GDMO) for CMIP [3, 2, 4]. The MIB specification is embodied in the implementation of management information exchange protocol han- dler (or, so called, protocol object or sub-agent) be- cause otherwise the protocol object would have in- sufficient information to process requests from the applications. Also, the MIB specification presents the schema of the management information base. Thus, it is important for the management applica- tion builders and network device builders to reach a consensus on the MIB specification to ensure that information needed by the applications is in the MIB and information in the MIB can be provided by the network devices. Unfortunately, in most ex- isting MIB documents, only the first item, i.e., what information should be in the MIB, is presented. In other words, the problem of how to get this infor- mation is left open. One reason for this current situation is to provide the portability and interop- erability of the MIB specification and network man- agement applications. The “glue” area between the network devices and the MIB is a big problem in building network management systems because people are forced to take an adhoc approach as we will describe later. Very recently, people who real- ize this problem come out a specification for Desk- top Management Interface (DMI) [1], which defines a common set of rules for accessing different types
