As we know that transition from single processor to multi-processors presents some challenges for shared memory design and implementation these are: keeping caches coherent and maintaining memory consistency. The problem of cache coherency occurs when any one processor tries to access a region of shared memory which has been modiûed in another processor’s private cache, but not yet written back to main memory, which results in a read to memory which is out of date. Memory Consistency Model is needed for a shared memory system to define the ordering in which reads and writes must be performed, both relative to each other in the same program and to other reads and writes by another program on another processor. The programmer must know the memory consistency model used by the hardware in order to ensure program correctness. Though there are many solutions to the problem, each memory consistency model has its own advantages and disadvantages and it is not always clear which protocol works the best for a particular system and application. Here we presented the unifying framework by which we describe, understand and compare the sequential and total store order memory model using MATLAB. Performance of the models here is based on the memory cycle count.
Abstract: In today’s era, Wireless Sensor Networks (WSN) is used in various application areas like home, health, agriculture to name a few. WSN comprises of large number of tiny sensor nodes. The main tasks of a node in WSN is to sense data, process and communicate with other nodes. When used in large numbers, large amount of data is generated during its lifetime operation. This data at times needs to be transferred from a node to the base station. Transferring a large scale of data consumes more energy because of long transmission time. Wireless Sensor Network’s data is concern with different data classes and different data formats. Data needs to be converted in different formats for generating information which results in data mining. Recent innovation in data mining technique receives attention in extracting knowledge from data gathered using WSN. In this paper, we have given an overview of wireless sensor network and data mining. We have also listed some WSN applications and looked at how various techniques of data mining have been used in WSN applications. Finally, we have recommended a data mining technique that can be used on monitoring data collected through WSN.

Abstract: The software quality prediction is a major issue these days. In order to develop software quality prediction model, one must first identify the factors that strongly influence software quality and the number of residual errors.
Wireless sensor network (WSN) have become most interesting area of research since last decade. The nodes in wireless sensor networks are capable of monitoring the conditions and co-operatively communicate to the network. Each node in the network has critical impact on the system behaviour, so it is important to simulate the functioning of the nodes before its deployment in real world. In this paper we have simulated a vehicle monitoring system using WSN for Bus Rapid Transit System (BRTS). This paper is divided into five sections. Introduction of BRTS and wireless sensor network is given in section I, overview of proposed architecture and its solution is discussed in section II, information of the tool used for simulation is given in section III. Simulation work of proposed architecture is shown in section IV. Finally conclusion is given in section V.
Abstract: The basic challenge in MANET is to design robust routing protocol adaptable to frequently changing network topology. On-demand ad hoc routing protocols uses a flooding based route discovery technique to find routes when needed. Since each route discovery incurs high routing overhead and latency, the frequency of such route discoveries must be kept low. On-demand multipath protocols compute multiple paths in a single route discovery to reduce overhead. In this paper, we simulated unipath Ad-hoc On-demand Distance Vector (AODV) routing protocol and On-demand Multi path Distance Vector (AOMDV) routing protocol. AOMDV is efficient when node mobility is high since it provides better statistics for packet delivery and throughput. But if routing overhead is a major concern, then AODV is preferred.
