Abstract

Abstract: To promote the transmission performance of multimedia streams in Wireless Multimedia Sensor Networks（WMSNs） in which deployment of nodes’ residual energy is not uniform，this paper proposes a novel Energy-Aware Compass Multi-path routing algorithm（EACM）.This algorithm can balance the residual energy difference of nodes and adjust the aggregation degree of multiple paths to balance the energy consumption and reduce the transmission delay of data packets in WMSNs.Simulations results show that the EACM can prolong the network lifetime effectively and reduce the transmission delay of data packets.

Key words: wireless multimedia sensor networks, energy balance multi-path routing, network lifetime, transmission delay, simulation

摘要： 针对节点能量分布不均匀的无线多媒体传感器网络中大数据量传输问题，提出一种无线多媒体传感器网络能量敏感多路径路由算法EACM。该算法通过平衡路由节点间剩余能量差异，调节多路径聚集程度来均衡网络能耗减少数据包在路径上的延迟。仿真结果表明EACM算法能有效地延长网络生存期，减少数据包在路径上的时延。
