【摘要】 针对移动传感器网络中传统的信标交换会引起通信暂盲的现象,在分析链路特性的基础上,提出了一种新型的自适应信标交换算法。在该算法中,工作节点依据不同的链路断开概率自适应地选择信标交换周期,空闲节点则基于链路寿命分布情况来选择固定的信标交换周期。仿真结果表明:该算法有效地减少了通信暂盲现象,并在控制开销、数据传送成功率这2个性能指标上都获得了明显的改善。更多还原

【Abstract】 To address the problem of temporary communication blindness caused by traditional beacon exchange in mobile senor networks,a novel adaptive beacon exchange algorithm is proposed on the basis of the characteristics analysis of the link.The working node calculates variable beacon change period according to different link broken probability,and the idle node selects the beacon change period by the distribution of link lifetime.Simulation results demonstrate that the proposed algorithm effectively reduces the phenomenon of temporary communication blindness and greatly improves the performance in terms of transmission success rate and consumption.更多还原
