Abstract(in English) In this paper, we focus on a system that collects vital data by WSN (Wireless Sensor Networks) from sensor nodes attached to a large number of exercisers. For increasing the number of supported nodes with WSN, it is necessary to utilize multi-channel communications, which can suppress the number of operating nodes per channel. However, in data transmissions using multi-channel communications, the reduction of operating nodes at each channel can increase the number of isolated nodes that have no neighboring node within their communication ranges. Therefore, a protocol called ACS-MAP has been proposed, which suppresses the duration for each node to be in isolated state by introducing autonomous channel selection and switch of isolated nodes. However, in ACS-MAP, the difference of the number of nodes with data transmissions in each channel becomes large depending on the distribution of nodes over each channel. In this paper, in order to solve this problem, we introduce a centralized operation to change the assigned channel of selected nodes considering the distribution of node locations. With computer simulations, we investigate the effectiveness of the proposed method.
