<p><P>PROBLEM TO BE SOLVED: To suppress wasteful transmissions of data, increase in the number of hops between nodes, and congestion of transfer data, when a mobile device moves and collects data inside a network, where a plurality of sensor devices having a function of transferring measured data by radio are arranged. <P>SOLUTION: When an access is tried by a mobile device to a plurality of nodes 501, 502, 503, 504, 506, ... in the sensor network 500 is detected, a future access probability to each of two or more nodes by the mobile device is computed. Information, related to the computed probability, is transmitted within the sensor network; and based on this probability, collected measured data are routed so that the number of hops in the nodes does not increase wastefully, and the data are transmitted to the mobile device. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
