摘要
随着无线通信的日益发展,无线自组织网络正逐渐从军用扩大到民用等诸多领域。但是无线自组织网络一般由电池供电,由于提高电池容量的技术进步缓慢,功率控制是一个重要的研究课题。无线自组织网络中的功率控制机制研究主要集中在3个方面,即网络层功率控制、链路层功率控制以及混合功率控制。重点是从分层的角度对功率控制进行阐述,主要介绍了网络层及链路层的功率控制,并介绍了一些节能协议。跨层设计综合考虑了各层性能能更好地为功率控制与节能服务。
With the development of wireless communications,wireless Ad Hoe networks are spreading from military areas to lots of civilian areas. However,Ad Hoe networks are supported by batteries,and battery technology of improving capacity progresses slowly,power control enhencement is an important issue. Researches on Power control can be concentrated as follows： power control of Network layer,power control of MAC layer and hybrid power control. The text plays emphasis on the power control of each layer, mostly introduces power control of Network layer and MAC layer. Moreover the text presents some energy saving protocols. The cross layer design takes account of the performance of each layer, may provides better services for power control and energy saving.
