摘　　要：以无线自组织网络的连通性作为研究对象,根据几何随机图中最小度原理,结合均匀分布、泊松分布、随机点模型网络、随机方向模型网络等几种网络的节点概率分布,计算网络中节点的最小度,得到网络1-连通度与节点数和通信半径的定量关系,证明网络连通性按照均匀网络、随机方向模型网络和随机点模型网络的次序减弱。The connectivity of wireless ad hoc networks were studied, including uniform networks, Poisson networks, networks using random waypoint model, and networks using random direction model. The analysis was based on the minimum degree theorem in geometric random graphs. The node degree was calculated by using the probability density function of node distribution. The quantitative relationship among 1-connectivity, node number and communication range was illustrated. It was shown that the connectivity decreased by the sequence of uniform networks, networks using random direction model, and networks using random waypoint model.
