AODV 协议是 Ad hoc 无线自组网中经典路由协议之一;针对 AODV 协议的缺点,提出一种基于蚁群算法改进的 AODV 路由协议;结合蚁群算法与 Ad Hoc 网络的特点,将蚁群算法应用于 AODV 协议,考虑节点负载、路径跳数、路径时延等因素,对 AODV 的路由组建和路由维护策略进行改进;通过在 NS2平台中设置不同的网络负载和不同的节点移动速度,对改进后的 AODV 协议进行模拟,仿真结果表明,该路由协议在分组投递率、平均端到端延时和归一化路由开销等性能上比 AODV 协议具有一定的优势,网络的健壮性和抗毁性得到增强。
AODV 協議是 Ad hoc 無線自組網中經典路由協議之一;針對 AODV 協議的缺點,提齣一種基于蟻群算法改進的 AODV 路由協議;結閤蟻群算法與 Ad Hoc 網絡的特點,將蟻群算法應用于 AODV 協議,攷慮節點負載、路徑跳數、路徑時延等因素,對 AODV 的路由組建和路由維護策略進行改進;通過在 NS2平檯中設置不同的網絡負載和不同的節點移動速度,對改進後的 AODV 協議進行模擬,倣真結果錶明,該路由協議在分組投遞率、平均耑到耑延時和歸一化路由開銷等性能上比 AODV 協議具有一定的優勢,網絡的健壯性和抗燬性得到增彊。

AODV protocol is one of the classic routing protocols in wireless Ad hoc network .Aimed at the deficiency of AODV protocol ,an improved AODV routing protocol based on ant colony algorithm has been proposed in this paper .Combined ant colony algorithm with characteristics of Ad hoc network ,applied ant colony algorithm to AODV protocol ,and considered the node load ,path hop ,path delay and other fac‐tors ,the routing construction and routing maintenance policies of AODV protocolhave been improved . Through setting up different network loads and node movement speed in NS 2 platform , the improved AODV protocol has beensimulated .The simulation results show that this protocol has certain advantages compared with AODV protocol in packet delivery fraction ,average end‐to‐end delay ,and normalized rou‐ting overhead and other respects .In the meantime ,the network robustness and anti‐destroying ability are enhanced .
