针对节点能量和可用带宽2个约束条件的问题,提出了一种基于移动Agent的QoS路由算法.该算法利用移动Agent采集网络中各节点的详细信息,以最大链路的生存时间作为选择路由的基础,增强了路径的稳定性;采用多路径策略,以缩短路由重构的时间;优先选择剩余能量多的节点,延长了网络的生存时间.利用网络仿真工具NS2进行的仿真实验结果证明,与AODV协议相比,该算法具有较高的包传输率和较低的端到端平均延时.
Aiming at the two constraints of node energy and available bandwidth, a QoS routing algorithm based on mobile agent is proposed in this paper, which uses mobile agent to collect the detailed information of every node in the network and choose the survival time of the largest link Which enhances the stability of the path.Multi-path strategy is adopted to shorten the time of route reconfiguration.Secondly, the node with more energy remaining is preferred to prolong the lifetime of the network.The simulation results using network simulation tool NS2 demonstrate that Compared with AODV protocol, the proposed algorithm has higher packet transmission rate and lower average end-to-end latency.
