Abstract: Wireless sensor networks with large numbers of portable sensor nodes has potential applications in a various fields, like surveillance, home security, military operations, medical, environmental and industrial monitoring. Due to rapid growth in electronic fabrication technology it is possible to manufacture the portable sensor node at low cost with better accuracy and sensitivity. Hence large numbers of portable sensor nodes can be deployed in the field to increase the quality of service of such wireless sensor networks. The exercise to use large numbers of sensor nodes will increases the probability of sensor node failures in such WSNs. QoS of wireless sensor network is mainly affected by failure of sensor nodes. Node failure is detected by measuring Round Trip Delay time of round trip paths and comparing them with the threshold values. By reducing RTD time, accuracy of fault detection technique can be increased.
Keywords: QoS, RTD time, WSNs.
