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,讨论节点临界的传输范围以及节点的平均度在什么情况下,保持Ad Hoc网络的k连通。首先对Ad Hoc网络连通度目前的研究进展进行了综述,其次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,基于仿真结果指出了相关文献的不足之处,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 most literatures focus on the Critical Transmission Range （CTR） and the averaged minimum node degrees in which the Ad Hoc networks could be kconnectivity.Firstly,this paper summarizes the present process on the connectivity and simulates it with the energy model.Secondly,this paper points out the insufficiencies in the relative literature and makes a prospect for the future research areas based on the simulation results.
