An Energy-Aware Routing and Filtering Node (ERF) Selection in CCEF to Extend Network Lifetime in WSN

摘要

Wireless sensor networks (WSNs) have unprecedented environment-monitoring capabilities with low cost, small size, and limited energy. In security protocols, the general approach for energy efficiency is to reduce the number of attacks while underlying routing protocols are often ignored. In this paper, we present an energy-aware routing and filtering node (ERF) selection to extend network lifetime in commutative cipher-based en-route filtering (CCEF). In addition to distance to the destination, the residual energy is considered for forwarding node selection. In a given path, filtering nodes are carefully selected based on attack information, presence of witness key and current state of a node in sensor network. Results demonstrate the validity of our simple approach to significantly prolong the network lifetime by balancing network energy consumption.
