MANET中基于蚁群算法的改进DSR协议*

为提高移动Ad hoc网络中DSR协议的服务质量,提出基于蚁群算法的改进DSR协议---ACOIDSR。ACOIDSR协议路由发现过程中,建立稀疏模式和稠密模式弥补DSR协议泛洪策略的不足；ACOIDSR协议路由选择过程中,利用路径长度、拥塞程度和链接可靠度计算每条路径的信息素数量,进而做出最佳路径的选择；ACOIDSR协议路由维护过程中,提出一种新的信息素衰退策略用于路由维护。最后,仿真实验用于ACOIDSR协议在端到端的延迟、路由负载以及能量消耗等方面分析。

ACO-Based improved DSR protocol for MANET

To improve the service quality of DSR in mobile Ad hoc network, an ACO-based improved DSR protocol is proposed. The establishment of sparse mode and dense mode make up the lack of the flooding strategy for DSR protocol in route discovery process; using the path length, degree of congestion and link reliability to calculate each path pheromone amount, and then make the best path choice in route choosing process; a new pheromone decay strategy for routing maintenance is proposed in route maintenance process. Finally, Simulation experimental is used for analysis of ACOIDSR protocol in end-to-end delay, routing overhead, energy consumption and so on.
