基于蚁群优化的无线多媒体传感网络QoS路由算法

摘要

A QoS routing algorithm of wireless multimedia sensor networks based on ACO is introduced. The ACO based QoS routing algorithm is designed on the basis of WMSNs QoS routing model and the queuing model of node is analyzed. Simulation results show that the algorithm has better performances than DD algorithm in lifetime and data delay when meeting the QoS requirements.%　　介绍一种基于蚁群算法的无线多媒体传感器网络WMSNs的QoS路由算法。本文在分析了WMSNs的QoS路由模型的基础上，设计了基于蚁群算法的QoS路由算法，并对节点排队模型进行了分析。仿真结果表明，采用该算法时，在满足网络QoS参数需求的前提下，节点平均寿命和数据包延迟要优于传统的DD算法。
