With the growing demand in Wireless Sensor Network (WSN), adversary attack on sensor node becomes major issue in current WSN deployment. The replica nodes which are generated by attackers receive the valuable information from the network in turn sends to the adversaries and at the same time transmits inappropriate message to the sink in the sensor networks. One of the existing paper presented Sequential Probability Ratio Test (SPRT) which reduces the overhead of sensor node transmission on the adversary conditions. However, the sensor node's mobility affected the query range being invoked for detection of replica node location with probability ratio. The energy efficiency of the sensor node also needs to be monitored for effective adversary sensor node detection using SPRT.
