Abstract (in Japanese) (See Japanese page) 
(in English) In sensor networks, a huge number of battery-driven sensing nodes are scattered across the sensing area, so that the power saving of these nodes in terms of both collecting and forwarding data may become very important.
A hierarchical sensor networks, in which the sensing area are divided into many small clusters and the cluster-head node corrects/compresses data from other nodes located in the cluster and transmit the sink node, can reduce power consumption of the whole network and multi-hierarchical structure is remarkable for power saving effect. However, the power consumption distribution of each sensing node is not investigated and there is no discussion in terms of the lifetime of the network. Thus in this paper, we first show the power consumption distribution in sensor networks with multi-hierarchical structure and explain the problem for selecting cluster-head nodes in the current scheme. Then we investigate some selection schemes to both reduce the power consumption of each nodes and extend the lifetime of the network.
