A Hop-based Energy Aware Routing Algorithm for Wireless Sensor Networks

摘要：

Wireless sensor networks(WSNs)have attracted quite attention due to theft wide potential applications. Up to now,a huge amount of energy efficient routing protocols or algorithms have been proposed to improve energy efficiency.In this paper,we try to prolong network lifetime by studying the relationship between hop number and energy consumption.A Hop-based Energy Aware Routing (HEAR) algorithm for WSNs is proposed.The simulation results show that our algorithm outperforms several existing protocols,such as shortest path algorithm,maximum remaining energy algorithm in the aspect of energy consumption and network lifetime.Depending on the real network environment,our algorithm can reduce energy consumption up to 50％ and improve the network lifetime up to 125％ comparing with the existing routing algorithms.
