摘要: “瓶颈节点”是在无线传感器网络中由于随机部署的原因产生了连接两个或是多个区域的孤立节点。由于这类节点对网络的生存周期存在着很大的影响,提出一种分布式瀑布型移动方案。该方案减少了节点移动的距离并节约了节点移动所消耗的能量,同时也减少了网络覆盖初始化的时间;通过移动一定数量的节点到“瓶颈节点”的附近来均衡节点的通信量,进而延长了整个网络的生存周期。仿真实验结果表明,该方法可以有效地提高整个网络的生存周期,均衡了节点的能量消耗,并缩短了节点重定位时间。

关键词: 移动节点, 瓶颈节点, 能量消耗, 网络生存周期

Abstract: "Bottleneck Nodes" are those connecting two or more isolated areas because of the random deployment. Compared with other nodes, these nodes are more important to the lifetime of the whole network. The paper proposed a distributed cascading movement solution. This solution can reduce the distance and save the energy by moving nodes, and it also reduced the time to initialize the network coverage. The solution can balance the networks communications and increase the networks lifetime by moving some nodes to its proximity. The simulation results verify that the proposed solution outperforms others in terms of network lifetime, energy consumption and the time of node relocation.

Key words: mobile nodes, bottleneck nodes, energy consumption, network lifetime
