无线传感器网络跨层优化研究

无线传感器网络系统的跨层优化理论在当前是一个研究热点.在传统的无线网络设计中,一般是沿用有线网络的设计思想,特别是利用因特网的设计思想来设计无线网络.然而由于无线传感器具有网络资源和能量受限的特点,这就使得传统的有线网络中分层设计的思想遇到了未曾预计的尴尬与挑战.本文对无线传感器网络中的跨层优化工作原理进行了叙述,比较了各个跨层优化技术的特点.最后阐述了当前跨层设计技术面临的挑战.

Research of Cross-layer Optimization for Wireless Sensor Networks

The cross-layer optimization theory of wireless sensor networks system has become a focus in the current study.The traditional wireless network design generally follows the design idea of cable network,particularly applies the design idea of the Internet in the design of wireless network.However,as wireless sensor networks have limited resources and energy,the hierachical design idea in traditional wired networks runs up against the unanticipated embarrassment and challenges.This paper first analyzes and co...
