| 摘 要： | 提出一种服务感知的跨层QoS(Quality of Service)路由算法(CLQDCR),结合AODV及DCR算法的特性,利用跨层设计的思想,以时延、干扰和能量作为QoS度量,采用区分服务的方式为实时多媒体业务和非实时文本业务提供不同的QoS保障.仿真实验证明,该算法在提高实时性能及全网负载均衡方面具有较好的性能.

| Abstract: | This paper presents a cross-layer QoS dynamic codeword routing (CLQDCR) algorithm for Wireless Multimedia Sensor Networks. It combines the advantages of AODV(Ad-hoc Distance Vector) and DCR(Dynamic Codeword Routing). Basing on the principle of cross-layer,the protocol adapt delay,interference and energy as QoS metrics,and provide Differentiated Services for Real time Multimedia streams and delay-tolerant Data. By presenting and analyzing simulation results,the CLQDCR is shown to result in good performance o... |
