一种改进的链路容量优化路由策略

设计能够适应高移动环境下的空基自组网路由协议是目前研究的重点方向。提出了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,首先预测出通信链路的有效时间,然后在满足数据的时延、带宽以及链路有效性等多约束条件下,路由协议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,设计的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,提高网络的吞吐量。

An Improved Strategy of Optimally Link Capacity Routing

The routing strategy in airborne ad hoc network is the major research direction,which can adapt to the high mobility environment.An optimal router strategy based on load balancing in airborne ad hoc network is proposed in this paper.The communication link available time is forecasted based on location information.Then the designed router protocol should satisfy the following multi-constraints:link availability,delay and bandwidth.Finally it considers the node load equilibrium as the optimal object in order that all the communication links have assigned proper packets to transmit.The simulation results show that the nodes have proper transmission loads that promote the whole network throughputs.
