提出了一种基于簇树的6LoWPAN无线传感器网络构建方案，该方案创建了基于簇成员数的簇生成算法，在该算法中，总是由簇成员数最多的簇首首先发起簇生成过程，从而使簇首总数达到最小。该方案还提出了当簇头或簇伴节点移动或失效时的簇修复算法和簇树修复算法。在修复算法中，选择权值最大的簇成员作为新的簇头或簇关联节点，以维护簇树拓扑结构，保证IPv6地址的正确性和路由的连续性，分析了该方案的性能，实验数据表明，提出的簇树拓扑结构更稳定，路由开销更低。
The paper proposed a scheme for constructing 6LoWPAN 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 could 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.
