Nowadays the application of wireless sensor network (WSN) has been increased. To provide Quality of Service (QoS), there is need of some development in the WSN. There are many developments made in wireless sensor network, due to escalation of usage there are considerable problems in WSN. The WSN is composed of number of wireless sensor node. The quality of service mainly depends upon wireless sensor nodes. If failure occurs in wireless sensor nodes, then whole network will collapse. Due to the collapse of whole network the quality of service decreases. The probability of failure increases with increase of number of sensor nodes.
In the proposed method, the faulty sensor nodes are detected by calculating the round trip delay (RTD) time of different round trip paths and comparing them with the threshold value. The scalability of this method is checked by simulating the WSNs with a large number of sensor nodes in Network Simulator 2 (NS2). Energy consumption is increased by redundancy and the network lifetime is reduced, cluster head fails to detect the faulty node which creates data loss problem. The necessity of the received signal strength measurement in the cluster head variation and assigning separate wavelength of each of the link in other fault detection techniques are overcome in this method.
