【摘要】 在采用多跳通信方式的分簇无线传感器网络中,接近sink点的簇头负担较重,容易过早耗尽能量而失效,引起大量簇重组。针对该问题,基于完全图理论提出一种能量高效可靠分簇算法以均衡簇间负载,设计动态簇头轮换机制来实现快速簇头选举和故障处理。仿真结果表明,该算法能延长网络生命周期、节约网络能耗、提高网络可靠性。更多还原

【Abstract】 In clustering Wireless Sensor Network(WSN) using multi-hop routing,the nearer to the sink node,the more load will be put on the header,headers near the sink node will quickly lose energy and cause a lot of process of re-clustering.Aiming at these problems,this paper proposes Energy-Efficient Reliable Clustering(EERC) algorithm for WSN based on complete graph to balance energy cost among clusters,designs a dynamic header alternation mechanism to supporting quick header selection and failure recovery.Simulation results show that this algorithm can overwhelm in prolonging network lifetime,reduce energy cost and support reliable data delivery.更多还原
