| 摘 要： | 为研究传感器网络在敌对环境中的隐藏问题,防止恶意节点的跟踪和破坏,提出了一个移动汇聚节点的移动策略.对隐藏问题进行分析和建模,并对穿越行为进行定义.在此基础上,提出了一种基于局部贪婪算法的移动策略,使得汇聚节点通过这个策略收集数据时,区域中的静止节点发送消息的次数最少(包括中转的次数),以此来减少整个网络被发现的可能性.通过3种比较算法的仿真,表明了该移动策略的准确性和有效性.

| Abstract: | To solve the hiding problem of wireless sensor networks in hostile environment and prevent the tracking and destroy of mali-cious nodes,a moving strategy for mobile sink is presented.Firstly,the hiding problem is analyzed and modeled and the traverse behavior of mobile sink is also defined.Based on these assumptions and definitions,a moving strategy is proposed.Using this moving strategy,the number of the transmission happened in the field and the probability of being detected will be reduced while the mobi... |
