摘要
网络负载是影响Ad Hoc网络性能的重要因素,网络负荷比较重时,局部的拥塞将导致网络性能的下降,分析研究现有负载均衡路由协议,并利用链路层信息,结合原Ad Hoc路由协议AODV提出了一种跨层负载均衡的路由协议方案,在选路过程中引入负载均衡机制,均衡网络流量,以提高网络时延、分组到达率等性能。最后用NS2软件仿真证明了改进路由算法的优越性。
Network load is one of the most key factors for affecting the performance of Ad Hoc networks. Ad Hoc networks degrade sharply if the traffic load in a single node is imbalance. This paper studied load balancing algorithms available and pro- posed a traffic-balanced method based on AODV protocol. Based on the proposed method, local congestion is reduced. Load balancing is introduced to the routing selection, which balances network flow to improve the performance of network end to end delay and packet transmission rate. The simulation results verify the superiority of the improved AODV routing protocol.
