摘　　要：引入一种新的抗毁性指标——自然连通度,建立了考虑能耗的移动Ad hoc网络拓扑结构抗毁性综合测度模型,在此基础上确定了基于网络拓扑结构抗毁性的最优发射半径。实验分析表明,该测度模型能有效刻画移动Ad hoc网络拓扑结构的抗毁性,具有最优发射半径的网络拓扑结构能较好权衡网络结构抗毁性和网络生命期。This paper introduces the natural connectivity as a new measure of invulnerability and proposes an integration measure model of invulnerability for Ad hoc network topologies based on power consumption.The optimal transmission radius based on the measure model is established.Simulation results show that this model can measure the invulnerability of Ad hoc network topologies effectively,and topologies with the optimal transmission radius can tradeoff the invulnerability and the network lifetime.

关 键 词：ADHOC网络 抗毁性 自然连通度 网络生命期
