Efficient way to detect fault node using round trip delay

Abstract: 

In recent years, Wireless sensor nodes are used in various applications to gather information. The sensor nodes which are deployed in the sensing area are prone to failure due to various reasons like malfunctioning, out of range, energy dissipation and so on. These sensor nodes have to identified and recovered to maintain the good quality of service (QoS). In this paper, the concept of RTT is implemented which is used to calculate the round trip time (RTT). Based on the RTT calculated, a fault node can be identified easily with the help of round trip delay (RTD). Finally, a recovery algorithm is proposed to recover the fault node in the WSN. When the defect node is identified and recovered, the QoS is improved which is shown below in the experimental analysis. The implementation of sensor nodes is carried out with the help of NS2 simulator.
