中文摘要：
针对无线传感器网络节点能耗受限和不同节点能量开销不平衡的问题，对于分层结构的无线传感器网络提出了一种分簇规模约束算法．该算法是通过对簇内节点数量设置上下限的方式，对簇规模大小进行限制．如果簇中节点的数量超过上限（U），该簇就被划分为两个簇；如果簇中节点的数量低于下限（L），该簇就会和邻居簇相结合．在自组簇的形成过程中采用该算法，可减少节点能量开销和增加簇的稳定性．
英文摘要：
To the energy limit of nodes and imbalance energy consuming among nodes, this paper propose a scale of cluster restriction algorithm for hierarchical wireless sensor networks. The algorithm uses a method that the number of nodes in each cluster is bounded by two constants called upper and lower bounds to restrict the scale of cluster. If the number of nodes in a cluster exceeds the upper bound, the cluster is divided into two clusters. If the number of nodes in a cluster becomes less than the lower bound, the cluster merges itself with one of its neighboring clusters. The algorithm not only reduce the energy consuming of nodes, but also increase the stability of cluster.
