摘要:

基于IEEE 802.11 MAC层协议模型,提出一种新颖的能够描述多条路径之间干扰程度的多径路由判据IAMM,并以此为基础,提出一种新的干扰感知的多径路由IAMR协议.IAMR协议通过2次选路,在保证单条路径性能的同时兼顾考虑路径之间的干扰因素.仿真实验表明,IAMR协议在端到端延迟、数据包到达率和吞吐量等方面均有较明显的性能提升.

Abstract:

Based on the 802.11 MAC protocol model this study proposes a novel routing metric IAMM (interference-aware multipath metric) to quantify the inter-path interferences. Based on IAMM, an interference-aware multipath routing (IAMR) protocol is proposed. Through a dual path selection method, IAMR takes into account not only the performance of each single path but also the inter-path interference between selected paths. The result of simulation shows that IAMR significantly improves the performance on transmission throughput, end-to-end transmission delay, and arrival rate of packets.

Key words: multipath routing protocol, interference-aware, wireless mesh networks
