Wireless Sensor Network (WSN) is an emerging technology that has resulted in a variety of applications. By using Bandwidth-Efficient Cooperative Authentication Network (BECAN) the false data injection filtering done efficiently and with less energy consumption. In WSN Sensor nodes are usually vulnerable to physical attacks or sensor node compromises easily. As the Sensor node could be easily compromised, the attacker can gain control obtain key values and change the properties of the node. This results in a false report to sink node and energy wastage in nodes.
