Abstract :
In most of application such as Habitat and Ecosystem- tem Monitoring, Seismic Monitoring, Civil Structural Health Monitoring, Monitoring Groundwater Contamination, Rapid Emergency Response, Industrial Process Monitoring, Perimeter Security and Surveillance Automated Building and Climate Control it is essential to observe or monitor the behavior of surrounding environment at a fine resolution over large spatial- temporal scales for this reason wireless Sensor Network (WSN) is used. WSN have high ability to connect physical world to the virtual world and sensor devices are tiny device and low battery devices due this use of wireless sensor network for monitoring surrounding behavior is increased time to time. Accuracy of WSN is enhanced by increasing the no of sensor within the network. As no of sensor increase this will increase the probability of failure of sensor within the network because WSN may be operated in unattended and hostile environment .If any of the sensor node is fails, this will lead to the change the network topology, also create network partitioning , increases distance between node pair and reduce the number of alternative available routes. In short it will degrade Network Performance of WSN, to improve network performance of WSN we have to find out faulty sensor node within the network. This paper will give one easy method for finding faulty sensor node within the network. This method measure Round Trip Time (RTT) of Round Trip Path (RTP) and compare the calculated RTT with threshold value(threshold value for RTT) if premeditated RTT is greater than threshold value or infinity then particular node from that respective path is declared as dead node or malicious node.
