Abstract :
Recent advance in ubiquitous technology has led the development of ubiquitous sensor environment in which various kinds of sensor devices provide sensor data. In this environment, since an enormous number of sensor devices join the network, it is effective to construct a P2P network for efficient retrieval of sensor data. In general, each sensor device periodically performs sensing based on the cycle set by itself. On the other hand, users often issue queries to acquire sensor data that were sensed at a specific time. In such a case, only the sensor devices (peers) that perform sensing at the specified time have to return their sensor readings. In this paper, we propose a novel P2P network construction method to achieve effective sensor data collection considering queries that specify a certain time. Our method clusters peers which perform sensing simultaneously, and constructs logical links between clusters whose peers sometimes perform sensing at a same time.
