【摘要】 移动自组网具有网络资源有限、拓扑结构变化迅速等特点,导致了重路由操作的频繁发生,而重负载节点导致的拥塞加剧了路由的不稳定性,极大的消耗了网络资源,降低了网络性能,移动预测与负载平衡有利于解决这个问题。提出了一种基于移动预测的负载感知(LAMP)路由协议,在选路过程中,避开拥塞节点,并采用移动预测机制选择一条最稳定的路由传输数据,减少了拓扑变化与重负载节点对路由稳定性的影响。仿真结果表明,与仅考虑移动预测的路由协议相比,LAMP协议在端到端延迟以及数据包到达率等方面都有较大的改善,提高了网络运行性能。更多还原

【Abstract】 Mobile ad hoc network is a self-organizing and dynamically reconfigurable wireless network with the characteristics of limited resources and variable topology.These features lead to rerouting operation more frequent and consuming the limited resources.Overload nodes with congestion reduce the stability of routes,so severely degrade the performance of ad hoc networks.The mobility prediction and load balance can contribute to efficiently solving this problem.This paper proposes a Load Aware protocol based on Mobility Prediction(LAMP).LAMP evades congested nodes and uses mobility prediction mechanism to choose the most stable route to transmit data.The protocol improves the network performance by reducing the influence on routing stability caused by variable topology and overload nodes.The simulation results show that,compared with the protocols which only use mobility prediction,LAMP gets better performance in end to end delay and delivery rate of packets,and improves the network performance.更多还原
