无线网络环境下的网络可靠性取决于网络中的多种因素.因此,在计算无线网络的2-终端可靠性时,应该考虑到网络中的各个组成部分对可靠性的影响.文中根据无线Mesh网的结构特性,提出了一种无线Mesh网骨干层的2-终端可靠性计算策略.该策略充分考虑到无线网络环境下节点故障和节点间的无线链路故障对网络的2-终端可靠性的影响,因此能够更加合理地评价实际环境中的无线Mesh网骨干层的2-终端可靠性.仿真实验证明,该策略能够有效提高无线Mesh网性能.

Network reliability in wireless environment depends on many factors, so when calcu lating the 2-terminal reliability of wireless networks, they should be taken into account. This paper presents a 2-terminal computing strategy, which is used for backbone of Wireless Mesh Networks. The proposed strategy is based on the structural features of Wireless Mesh Networks, and gives full consideration to effects of the wireless node fault and the link fault between the pair nodes. Therefore, it can provide a reasonable evaluation for Wireless Mesh Network backbone layer in actual wireless environment. At last it is proved through the simulation that the given strategy can effectively improve the wireless network performance.
