| 摘 要： | 在考虑节点剩余能量和节点探测信号强度的基础上,提出了一种面向目标跟踪的无线传感器网络动态分簇方法。由于在簇首选择时考虑了节点的剩余能量,因此可以有效地避免簇首节点能量不足导致的跟踪失败。方法既能保证各个节点均衡地担任簇首节点,又能避免簇首切换过于频繁,因此可以延长网络的使用寿命。计算机仿真结果表明,在满足簇首节点能量需求和簇内节点大部分能观测到目标的情况下,应该取尽量小的能量阈值和尽量大的距离阈值。 |

| Abstract: | A dynamic clustering method of wireless sensor network for target tracking was proposed considering residual energy and received signal energy intensity of nodes.Because the residual energy of the nodes was considered when choosing cluster heads the fail of tracking caused by shortage of node's energy could be avoided.The method can not only make each node play the role of cluster head evenly but also avoid the cluster heads switching too frequently.Therefore the life of network can be prolonged tremendously.The results of simulations show that:to satisfy the energy requirement of cluster head and guarantee that most of the nodes of cluster can sense the target the energy threshold should be as small as possible and the distance threshold should be as big as possible. |
