From few years, wireless sensor networks (WSNs) applications have been increased due to its vast potential to connect the physical world to the virtual world. Similarly an advance in microelectronic fabrication technology reduces the cost of manufacturing portable wireless sensor nodes. It becomes a Fashion to apply the large numbers of portable wireless sensors In WSNs to increase the quality of service (QoS). The QoS of such WSNs is mainly affected by the failure of sensor nodes. Chances of sensor node failure increases with increase in number of sensors. In order to maintain the better QoS under failure conditions, identifying and detaching such faults are essential. In the proposed method, faulty sensor node is detected by measuring the round trip delay (RTD) time of discrete round trip paths (RTP)and comparing them with threshold value. In this we are experimenting on two sensor nodes and one control unit(Master Node), communication among these nodes is established through Zigbee wireless technology
