Abstract

Energy efficiency is the essential consideration in advances of wireless sensor networks (WSNs) usefully designed for low data rate, low power consumption, and low-cost networking. Mindful of the above constraints, selecting an appropriate routing protocol can significantly improve overall performance with limited sensor network resources, especially energy awareness in WSNs. We propose an energy-aware routing protocol improved by our adaptive-gossip algorithm that will reduce the redundant routing messages so that it can minimize the overall energy consumption of a WSN. To analyze the energy efficiency, we introduce two energy performance metrics: Delay*Energy and Normalized-RoutingLoad*Energy. These metrics suggest that energy consumption heavily depends on both packet losses and packet delivery successes that affect delay and routing overhead respectively. We present both analytical and experimental results thoroughly to evaluate our adaptive-gossip proposal, and demonstrate its advantages over flooding and static-gossiping based protocols for densely deployed networks and different types of network such as peer-to-peer and multi-to-one.
