Development of Cluster Routing protocol in Homogeneous networks for Randomly Deployed MSN in WSNs

摘要

In Wireless Sensor Networks (WSNs), localization is one of the most important technologies since it plays a critical role in many applications, e.g., target tracking. If the users cannot obtain the accurate location information, the related applications cannot be accomplished. Localization process is necessary to report the origin of events, routing and to answer questions on the network coverage, assist group querying of sensors. The efficiency of the sensor network is measured in terms of the coverage area and connectivity. Therefore coverage is a factor must be considered during the deployment. In this paper, we propose a range-free algorithm which will calculate position of a node using distance vector calculation. To achieve the maximum coverage and better connectivity mobile sensor nodes (MSNs) will set themselves at the center of the hexagon on the instruction provided by the BS which is located at one of the corner in the deployment area. Simulation results are compared with CPVF scheme in terms of number of MSNs required for same coverage area and average movement required by MSNs to fix themselves at the desired location and energy efficiency.
