摘要
针对移动自组网路由协议的性能受到节点密度影响的问题,研究路由效率与节点密度的相关性。统计AODV路由协议的NS2仿真结果并进行最小二乘线性回归分析后,再运用Matlab对两者的相关函数进行拟合。检验结果表明拟合效果较好,验证了路由效率和节点密度的线性关系。实验得到的相关模型为改进移动自组网路由协议的性能提供了依据和方法。
Aiming at the issue of the performance of routing protocols in Mobile Ad Hoe Network affected by node density, relativity of routing efficiency and node density is studied. Maflab is used in fitting related function of routing efficiency and node density after the statistics of the NS2 simulating results of AODV protocol and the Least Square regression analysis. The test result indicates the fit gets good effect and the linear relation of routing efficiency and node density is validated. The related model proposed in the experiment provides basis and means for improving the performance of routing protocols in MobUe Ad Hoe Network.
