为评估多态无线传感器网络(WSN)的可靠性并降低其计算的组合复杂度,构建了节点三态的 WSN 模型,给出结合信息流动力学的时延约束下三态 WSN可靠性符号化定义,提出了基于 MMDD的三态 WSN可靠性符号算法,该算法通过自定义操作对三态 WSN按需构建,不需枚举所有路集,可有效地降低算法的空间复杂性。实验结果表明,MMDD算法能有效分析时延约束下三态 WSN可靠性,且相比 Robert算法具有更高的运行效率。

To deal with the exponential explosion of reliability analysis of multi-state wireless sensor networks,a wireless sensor network model where each sensor node has three states is built,and combined with information flow,the computing process of reliability is defined.And then a multi-state multi-value decision diagram based on symbolic reliability assessing algorithm which doesn’t require explicit enumeration of minimal path vectors is proposed.The simulation result shows that the MMDD-based algorithm can calculate the two-terminal reliability of three-state wireless sensor networks with delay con-straint and has a higher performance of storage than Robert algorithm.
