| 摘 要： | 无线传感器网络的分簇密度是不定的,通过控制簇头发射功率将能使分簇密度控制在合理范围内.无线传感器网络的"簇头--成员"结构与CDMA的"基站--移动台"结构相似,可以采用CDMA的功率控制机制对无线传感器网络的最小ID分簇算法进行优化.改进后的算法和步骤得到了描述,并给出了控制簇头发射功率的流程图.

| Abstract: | The nodes in wireless sensor networks are broadcasted randomly,which causes the distribution of the nodes and the clusters asymmetrical.This situation affects performance of networks.The power control technology of cluster heads was needed to optimize framework of networks.These are similar between 'clusterhead-member'in wireless sensor networks and 'basestation-mobile'in CDMA.Optimizing Lowest-ID Clustering of wireless sensor networks by using power control mechanism in CDMA and the algorithm and its process are described.Flow chart of controlling clusterhead transmit power is given out. |
