| 摘 要： | 在拓扑结构变化较小的无线传感器网络中，为了减小分簇算法在簇头选择过程中的能量损耗，该文提出一种分簇拓扑控制算法. 该算法以功能较强的异构簇头为中心，将一个簇分为内外两层，外层再进一步分成可以并行工作的多个子区，既保留了以簇头为中心的控制方式的高效性，又兼有多跳的灵活性. 仿真分析与实验证明，以该算法构成的系统具有以下优点：减小了节点的平均发送半径，均衡了能耗；有效降低了簇间干扰；提高了系统的吞吐量.

| Abstract: | In wireless sensor networks in which the topology change is small, to reduce energy consumption in cluster head selection, a cluster-based topology control algorithms is proposed. The cluster head is made much more powerful, partitioning a cluster into two rings. The outer ring is further divided into smaller sectors. This algorithm has advantages of both high efficiency in controlling cluster head center, and flexibility of multi-hopnodes. A system based on HCTCA can reduce the average transmission radius of nodes and inter-cluster interferences, and improve the network throughput. |
