Abstract

Recently, Technology of sensor networks develops rapidly. In addition, people have started utilizing many kinds of sensors. Sensors independently collect environmental information all over the world. Unfortunately those sensed data are not shared and open to the public. Therefore, we have constructed super-large-scale sensor network system to share sensed data collected from sensors all over the world. We call such a project Live E!. In a part of Live E!, To sense a public area in whole, we assume public objects(mailbox, bus stop, dumpster) uniformly allocate in a district evenly is equipped with a sensor and a wireless device. The public objects often dose not have connectivity to a network. Those are Isolated Wireless Sensor Nodes (ISNs). Then, we need to consider the way of collecting from the ISNs. Accordingly, we utilize a Patrol Node (PN) that moves around ISNs, and collects sensed data from ISNs. The ISN stores the sensed data until the time PN comes back. However, because the communication time to the PN depends on the speed of the PN, ISNs can not necessarily transmit all the maintained sensed data to the PN. Therefore, we suggest that the ISN should send adaptive data according to the speed of PN. We propose a technique for transmitting adaptive data depending on the movement of the PN. In addition, we have implemented a prototype of our proposal and verified the effectiveness of our proposed system. Finally, we show that our system improves the performance of the sensor network.
