自组织网络路由协议及仿真技术研究

摘要

Self-organising network routing protocol is an important core component of wireless communication technology.Aiming at the limitations in most of the current designing of self-organising network routing protocol, we studied the parameters of relative position between self-organising network node and adjacent node on the basis of self-organising network structure and mobility model.According to the size of its relative position parameters, we presented the improved example of self-organising network routing protocol.Applying the network nodes mobile tool NS2 simulation platform, and based on the estimation of delay time between end-to-end in networks, we carried out the corre-sponding network performances evaluation before and after the improvement of network routing protocol.Simulation experiment showed that the improved wireless self-organising network protocol could improve network performance effectively.%自组织网络的路由协议是无线通信技术的重要核心部分。针对目前多数自组织网络协议设计的局限性，依据自组织网络结构和移动模型，研究自组织网络节点与临近节点之间的相对位置参数。依据其相对位置参数大小，提出自组织网络路由协议的改进算例。应用网络节点移动工具NS2仿真平台，基于网络端到端之间的延时时间判断，进行相应的网络路由协议改进前后的网络性能评价。仿真实验表明，改进后的无线自组织网络协议能够有效地提高网络性能。
