一种适于波束切换移动自组网的邻居发现改进算法

Improved Neighbor Discovery Algorithm for Beam Switching Mobile Ad Hoc Network

基于多波束切换的移动自组网系统在未来通信中具有广阔的应用前景,邻居发现是基于多波束切换的移动自组网系统的关键技术之一。现有基于多波束切换的移动自组网邻居发现算法在波束交叠情况下无法选择最优通信波束,为了解决基于多波束切换的移动自组网邻居发现过程中的最优通信波束选择问题,提出一种改进算法,在邻居发现过程中增加接收信号质量评估机制,增强网络的稳定性,提高网络吞吐量,并通过仿真验证了在波束交叠的情况下系统的累计平均接收电平优于传统方法。

The mobile ad hoc network system based on multi-beam switching has broad application prospects in future communications.Neighbor discovery is one of the key technologies of the mobile ad hoc network system based on multi-beam switching.Existing multi-beam handover based mobile ad hoc network neighbor discovery algorithms cannot select the optimal communication beam under the condition of beam overlap.In order to solve the problem of optimal communication beam selection in the process of multi-beam handover mobile ad hoc network neighbor discovery,we proposes an improved algorithm which adds a received signal quality evaluation mechanism into the neighbor discovery process,enhances the stability of the network,and improves the network throughput.Simulation results show that compared with traditional algorithms,the improved algorithm proposed performs better on the cumulative received signal level under the condition of beam overlap.
