摘要

In recent years Wireless Sensor Networks (WSNs) are the most widely used networks and got attractive applications in various fields such as medical, military, safety agriculture and environmental monitorings etc. People are attracted to the networks which provide good services with less cost and judges the network based on their experience of network performance. The network performance seen by the customers is called as network Quality of Service (QOS). Hence to increase this QOS huge numbers of nodes are positioned. But due this increment in number of sensor nodes possibility of node failure also increases, this imposes to find an accurate faulty node detection algorithm so as to maintain network QOS. This paper presents an algorithm to detect faulty node present in WSNs. The algorithm is based on Round Trip Delays (RTDs) and Round Trip Paths (RTPs). First the proposed algorithm is experimented by taking six sensor nodes; later on the scalability of this proposed detection algorithm is demonstrated by simulating wireless sensor network with large number of nodes.
