摘要： 针对多对一的无线传感器网络“热点”问题，提出了一种基于多准则决策方法的不等簇数据收集算法 (unequal clustering data gathering algorithm based on multiple criteria decision，UCDGAMCD).采用直觉模糊层次分析法和层次模糊积分的多准则决策方法来竞选簇首，提出了一个新的簇首竞争半径，使其能够适应节点能量异构及节点非均匀分布的网络环境.根据邻居簇首的剩余能量和传输能耗，提出了簇首间按比例分配传输数据的路由方式，使其能量消耗更加均衡.仿真结果表明UCDGAMCD在节点均匀和非均匀分布的两种实验场景中都获得了较长的网络寿命.

Abstract: Focusing on the hot spot problem in many to one wireless sensor networks， an unequal clustering data gathering algorithm based on multiple criteria decision (UCDGAMCD) was proposed. The intuitionistic fuzzy analytic hierarchy process and multiple criteria decision making of hierarchical fuzzy integral were used to select cluster heads (CHs)， and a new cluster head competition radius was proposed to make it fit for the network scenarios with energy heterogeneous and nodes non-uniform distribution. To balance energy consumption， a routing algorithm with data ratio distribution was proposed based on residual energy of CHs and transmission energy consumption. The simulation results demonstrated that UCDGAMCD can obtain higher network lifetime in two scenarios—node uniform and non-uniform deployment.
