摘要: 介绍了一种基于位置信息对定向天线传输方向进行控制与调整的调度策略. 在低算法复杂度的基础上, 利用波束集中特性, 改善了分组递交率、吞吐量、时延以及开销等性能, 提升了自组织网络的抗干扰能力. 仿真结果验证了该调度机制的有效性, 同时表明, 不同的路由协议由此所获得的性能改善存在较大的差异.Abstract: A scheme by means of position information provided by localizer is presented and used to adjust the directivity of directional antennas with lower realizable complexity. Converged beams can upgrade the anti-jamming capacity of ad hoc networks by improving performance of delivery, throughput, delay and toverhead. Detailed simulations explain the availability of this mechanism, and also results show that different routings with directional beams have different behavior.
