无线传感器网络中基于延迟与能量平衡的背压调度算法

摘要

Wireless sensor networks have matured in all areas of people's lives as a modern network technology. However, how to effectively use the energy sensor node has always been a key issue in the study of wireless sensor networks.The back-pressure algorithm is proposed to ensure that the throughput of the network is optimized.However,the effect of delay perform-ance of the network system is not very satisfactory.In this paper,the authors propose a modified backpressure algorithm based on wireless sensor networks.To some extent,it ensures that the throughput is optimal and effectively considers the contradic-tion between energy use and delay costs.And,a relatively balanced result is obtained between the two factors.%无线传感器网络作为一种现代化的网络技术已经成熟应用于人们生活的各个领域.但是,如何有效的利用传感节点能量一直是研究无线传感器网络的一个关键问题.背压算法的提出能够保证网络的吞吐量最优化.然而,数据包的延迟性能效果却不是很理想.本文提出了一种基于无线传感器网络的改进的背压算法.在某种程度上,此算法能够确保吞吐量的最优化前提下,有效的综合考虑能量利用与延迟代价相互矛盾的问题.并且,能够在两个因素间得到一个相对平衡的结果.
