基于信任机制的最短路径TAODV路由协议仿真分析

Simulation Analysis of the Shortest Path TAODV Routing Protocol Based on Trust Mechanism

为了弥补AODV(Ad Hoc on Demand Distance Vector)路由协议安全方面的缺点,同时获取基于该优化协议下的最短路径,文中采用信任机制模型方法,在原始AODV路由协议上改进TAODV(Trusted Ad Hoc on Demand Distance Vector Routing Algorithm)路由协议。该协议以各个节点的信任值为基础进行相关运算,从而判断在路由协议运作过程中的路径信任值。通过在MATLAB平台中对相关参数进行设置,对改进后的TAODV协议进行模拟。仿真结果表明,改进后的TAODV路由协议在归一化路由开销、最小跳数和最优路径方面均优于传统的AODV路由协议,同时增强了网络的鲁棒性和抗毁性。

In order to compensate for the shortcomings in the security of the AODV(Ad Hoc on Demand Distance Vector)routing protocol while obtaining the shortest paths based on this optimized protocol,a study of a TAODV(Trusted Ad Hoc on Demand Distance Vector Routing Algorithm)routing protocol that improves on the original AODV routing protocol is proposed using the trust mechanism model approach.This protocol performs the relevant operations based on the trust values of each node to determine the path trust values during the operation of the routing protocol.The simulation results show that the improved TAODV routing protocol outperforms the traditional AODV routing protocol in terms of normalized routing overhead,minimum hop count and optimal path,and enhances the robustness and destructiveness of the network.
