空基自组网中基于负载均衡的路由策略

摘要

Aiming at the problems of load imbalancing and lower throughout, this paper proposes an optimal routing strategy based on load balancing in airborne Ad Hoc network.The communication link available time is forecasted based on location information.Then the designed routing protocol need satisfy the following multi-constraints: link availability, delay and bandwidth.It considers the node load equilibrium as the optimal object in order that all the communication links assign proper packets to transmit.Simulation results show that the nodes have proper transmission loads that promote the whole network throughputs.%针对空基网中节点负载失衡以及吞吐量低下的问题,提出基于负载均衡的优化路由协议.该协议在获得位置信息的前提下,预测出通信链路的有效时间,在满足数据的时延、带宽以及链路有效性等多约束条件下,以均衡节点负载为优化目标,使得网络节点都能合理承担数据传输任务.仿真结果表明,该路由协议能够保证网络节点合理分担传输任务,充分利用链路资源,从而提高网络的吞吐量.
