Efficacy for the improvement of node efficiency in the radiation affected area of wsn

Abstract

Wireless Sensors in network shows incredible usage in crucial environment. Several newlinenumber of sensor nodes are used in network to monitor specified area. Sensor nodes newlineare very tiny device with constrained limited resources. Resources are intelligent in newlinedoing their work efficiently in usual environment. Sensor nodes senses the monitoring newlinearea, processes the data and forwards the information to sink node in an effective newlinemanner with limited battery power. newlineIntruder introduces the unusual activates in area monitored by WSN to decrease the newlineefficiency of sensor nodes in network. Suppose radiation attack is encountered in a newlinespecified area monitored by WSN. Due to attack nodes are affected by radiation and newlineexpose transfaulty behavior. This will disturb the working environment. Affected nodes newlinesenses the area of interest but fails to communicate with neighbor. Communication newlinefailure, packet loss, drain of energy will take place. In addition to that, the intruder can newlineintentionally hack some nodes to send uncertain data. In such situation, need to identify newlinebehavior of the nodes by analyzing the data and remaining energy for taking decision newlineto forward the sensed information from nodes to base station or not. newlineAvoid all these happening in the area monitored by WSN. This thesis presents energy newlineefficient clustering approach with security mechanism to improve the imperativeness newlinecapability of the nodes and extend the life time of network framework. Securing the newlinesensed data within and outside the cluster from key based management approach and newlineencode the data by using RSA algorithm. Data reduction and data aggregation newlinemechanisms will avoid unnecessary transmission of normal data and also avoids the newlineworkload of sensor nodes in network to minimize the energy consumption. newlineCommunication between the nodes will continue even in the radiation influence newlinecondition to avoid packet loss and delay in reach. newline newline
