无线自组网MAC层和网络层节能策略

无线自组网固有的分布式、自组织特性使得它具有更多的特殊性,对无线自组网络的设计也提出了更多的挑战。针对无线自组网协议设计中的节能技术进行综述,通过分析无线网络数据传输中能量消耗模型,得出节能设计的基本准则,然后分别对媒体访问控制层和网络层的节能策略进行介绍,给出各自进行节能设计的思路。最后指出无线自组网络的节能策略设计需要综合网络通信协议的各层的特点进行跨层设计。

MAC and network layer energy-efficient strategy for mobile Ad Hoc networks

Mobile Ad Hoc network features itself as self-organizing,multi-hop wireless network and this give rise to challenges for the network design,including high network energy efficiency consideration because typical applications of Mobile Ad Hoc network often assume limited power resource of network participants.At the beginning,current research status of energy-efficient technique in Mobile Ad Hoc network is summarized.Then based on the analysis of Energy-consume Model for data transmission in wireless network,principles for the energy-efficient design for wireless Ad Hoc network both in Media Access Control（MAC） layer and network layer are introduced.Finally,Further improvement on energy saving should consider cross-layer design.
