| 摘 要： | 为了有效评估无线Mesh网络的可靠性，提出一种基于多径路由的网络可靠性评估方法. 研究无线Mesh网络的高移动性和链路失效率，以及多径路由附带的多径衰减对网络可靠性的影响. 实验表明，在无线Mesh网络中利用多径路由比分解路径的网络可靠性高，链路生命周期比传输流量的生命周期短，这对于降低端到端时延和提高整个网络的可靠性有重要意义.

| Abstract: | In order to evaluate reliability of wireless mesh networks (WMN), a new method for evaluating network
reliability based on multipath routing (MP-NRE) is proposed. High mobility and ratio of link failure are studied.
Incidental multipath attenuation has influence on the network reliability. Experimental results show that network
reliability is higher with disjoint path than with multipath routing in WMN, and link lifetimes may be relatively
short compared to traffic flows. This is significant for WMN to improve network reliability and reduce end-to-end
delay. |
