The widespread application of Wireless Sensor Networks (WNSs) is obstructed by the severely limited energy constraints and security threat for sensor nodes. Since traditional routing and security schemes are not suited for these networks, a large part of research focusses on energy efficient routing protocols while extending the network lifetime. Uneven distribution of communication loads result in network partitioning. Traditional novel route filtering approaches, notably Commutative Cipher based En-route Filtering (CCEF) saves energy by early filtering of false reports. However this approach main focus is security not network lifetime is limited by fixed paths and underlying routing not suitable for WSNs.
