摘要： 基于距离向量的按需路由协议是adhoc网络中一种具有代表性的按需路由协议.与传统路由协议相比,按需路由协议减少了建立和维护路由所需要的开支,但是随着网络节点发送数据量的增加,网络性能会迅速下降.针对这一问题,提出了一种简单有效的均衡流量改进AODV协议——TB-AODV协议.在TB-AODV协议中,每个节点根据本地链路层的负荷,决定拒绝或接受收到的路由请求,以避免加重局部拥塞,使得网络的负荷能更加均匀地分布.仿真结果表明,改进后的协议提高了网络的吞吐率,降低了分组传送的平均端到端延时,改善了网络性能.

Abstract: Compared with the traditional table-driven routing protocols, the AODV routing protocol reduces routing overhead in dynamic maintenance of routes. However, with AODV, network performance degrades rapidly with the increase of offered load. In this paper, we propose a simple and effective modified version of AODV, named Traffic-Balanced AODV (TB-AODV). In this protocol, each node, basing on its local MAC load status decides whether it can accept routing requests from other nodes or not. Simulation results show that TB-AODV achieves better overall performance than AODV.

Key words: ad hoc, AODV, routing, MAC
