在对网络中路径的能量、时延、可靠性等参数表示为Vague集的基础上,提出了基于Vague集的多准则评价模糊决策路由选择算法.通过比较隶属度、非隶属度、Vague集距离和贴近度值选取网络最优路径.数值计算和仿真试验表明该算法能够较好解决无线传感网络在复杂环境不确定链路多准则约束最优QoS路由选择问题.
In this paper ,on the basis of the measurement parameters ,such as energy ,delay ,reliability ,and other factors ,which are represented as vague sets ,multi-criteria evaluation of fuzzy decision routing algorithm based on vague sets is proposed . By comparing the degree of membership , non-membership ,Vague sets distance and similarity values ,it selects the optimal network path .Numerical experiments show that the proposed algorithm can solve the multi-criteria optimal QoS routing selecting problems , which are in the uncertainty link of complex environment among wireless sensor networks .
