【摘 要】提出了基于簇树的6LoWPAN无线传感器网络构建方案,此方案提出以簇内节点数量为度量参数的簇生成算法,在簇生成算法中,总是簇内节点总数最多的簇首节点首先发起簇的生成过程,因此实现了簇首节点数量最小化.此外,本方案还提出了簇首节点及簇关联节点移动或失效时的簇及簇树的修复算法,即基于簇内节点的权值选举新的簇首节点或簇关联节点,以维护簇或簇树的拓扑结构,确保IPv6地址配置和路由的连续性及正确性.对本方案进行了性能分析,分析结果验证了其构建的网络结构稳定性更强,路由功耗更低.%The paper proposed a scheme for

constructing 6L0WPAN wireless sensor networks based on the cluster tree. The scheme created the cluster generation algorithm based on the number of the cluster members, and in the algorithm, it was always the cluster head with the maximum number of the cluster members that first launched the cluster generation process, so that the total number of the cluster heads couid reach to be minimum. In addition, the scheme also presented the cluster repair algorithm and the cluster-tree repair algorithm when the cluster heads or the cluster associate nodes move or fail. In the repair algorithm, the cluster member with the maximum weight was selected as the new cluster head or the new cluster associate node in order to maintain the cluster tree topology and to ensure the IPv6 address

correctness and the routing continuity and accuracy. The paper analyzed the performance of the proposed scheme, and the experimental data shows that the proposed cluster tree topology is more stable, and the routing cost is lower. 【总页数】3页(P1533-1535) 【作 者】王晓喃
