无线Ad hoc网络的连通性与抗摧毁性

为了使Ad hoc网络能持续保持连通,覆盖性与抗摧毁性必须加以考虑.在任何两个一跳覆盖区必须通过公用信道传输信息的前提下,通过分析给定区域内信道节点的特征,提出了网络覆盖优化模型和规划方法,完成了区域的完全覆盖.针对模型的抗摧毁性能,提出了利用频率代替直接计算概率的算法,并在此基础上分析了随机抽取若干信道节点后整个网络的抗摧毁性.模拟实验结果证明,采用这种划分方法可以利用较少的信道完成对网络的覆盖,并能够得到较好的网络连通性和抗摧毁性能.

Research on connectivity and withstand wreck on wireless Ad hoc network

For the purpose of persistent connection of Ad hoc network,overlay and withstand wreck must be taken into consideration.Suppose that any two nodes had to use the public transmitting nodes in order to connect to each other,by analyzing the features of the nodes in a fixed area,the model and programming method were proposed to optimize the overlay scheme,and the whole area was completely covered.According to the withstand wreck of the network,an arithmetic was proposed to replace computing probability directly by frequency,and on the basis of that,the network's capability of connection and withstand wreck was analyzed thoroughly.The result of simulating experiment proves that the capability of the network can be evaluated easily with the proposed scheme.
