Abstract(in English) As for the wireless multi-hop network that uses CSMA/CA, application to data acquisition systems that collects information from the sensor is paid to attention because it can construct the network autonomous. There is an advantage that the network can be simply constructed because the sensor constructs the network autonomous mutually. On the other hand, crowding occurred when the sensor that exceeds the network capacity is disposed and there is a problem that the radio network fails. Therefore, it is a critical to understand the network capacity corresponding to the number of terminals set up beforehand. The network capacity in the multi-hop network that uses the tree topology that makes GW a vertex is analyzed in the theory in this paper. Moreover, the validity of the analysis is confirmed by simulating and comparing it with the analytical result.
