摘　　要：连通度是Ad Hoc网络的根本属性.保持网络的连通性对于提高网络的吞吐量至关重要.目前的研究主要以概率论方法为理论基础,讨论节点的发射半径在什么范围内,保持Ad Hoc网络的k连通.文中对Ad Hoc网络连通度目前的研究进展进行了综述,在引入能量模型的基础上,对Ad Hoc网络的连通度进行了仿真,并基于仿真结果,提出了Ad Hoc网络保持连通的临界传输范围,最后对将来的研究方向进行了展望.Connectivity is one of the essential properties of Ad Hoc networks. It is very important to keep the whole system connective for the improvement of the networks＇ throughput. Mainly based on the method of the probability,the current researches investigate the mobile nodes in what kind of critical transmission range （CTR）, the network topology is k connective. Firstly, this paper summarizes the present process on the connectivity and simulates it with the energy model. Secondly, this paper puts forward the CTR and makes a prospect for the future research areas based on the simulation results.
