摘要
在无线传感器(Wireless Sensors Networks,WSN)中,由于节点能量有限,可能导致节点过早死亡,引起网络结构发生变化,链路稳定性变差.针对该问题文中提出了一种基于链路预测和能量感知的机会路由协议ELPOR(Opportunistic Routing Protocol Based on Link Prediction and Energy Sensing,EL-POR).该协议综合考虑节点能量和各节点之间链路连接的概率,从潜在的候选转发集中选择一个中继节点,以实现能量的高效利用和数据的可靠传输.仿真结果表明,该协议能够有效均衡网络能耗、提高吞吐量和延长网络生存周期.
Abstract
In Wireless Sensors Networks,nodes may died prematurely due to the limited energy of nodes,resulting in changes of network structure and poor link stability.Aiming at this problem,an opportunistic routing protocol based on link prediction and energy awareness is proposed in this paper.Considering node energy and the probabil-ity of link connections between nodes,the protocol selects a relay node from the potential candidate forwarding set to achieve efficient energy utilization and reliable data transmission.Simulation results show that the protocol can effectively balance network energy consumption,improve throughput and prolong network lifetime.
