摘要
移动自组网是一种没有基础设施的临时性自组织网络,在其应用时路由协议是必须确定的基础性问题.随着业务的发展和MAC层协议的支持,移动自组网会适应不同速率的业务,能以不同的速率发送报文.基于NS2的在2 Kbps,144Kbps,1 Mbps,2 Mbps,11 Mbps等5种发送速率下,对AODV路由协议进行的仿真研究和性能分析结果表明:AODV在低速率业务下工作良好,同时也能支持高速率业务.
Mobile ad hoc netwark is an infrastructureless temporary self- organized network. The muting protocol is an important foundation problem when deployed. Along with traffic development and MAC protocol support, packet can be transmitted with different rate when multi - rate traffic adopted in mobile ad hoc networks. In this paper, AODV muting protocol is simulated with five different rates, i.e. 2 Kbps, 144 Kbps, 1 Mbps, 2 Mbps, 11 Mbps, and its performance is analyzed. It is showed that AODV muting protocol work well under low rate, and can support high rate traffic.
