PROBLEM TO BE SOLVED: To transmit a large amount of data such as images and to secure a communication path even when relay nodes have a trouble, or a power supply breaks down, or on other occasions, in a wireless network using wireless sensor nodes for a low communication speed and short-distance communication. SOLUTION: Out of wireless sensor nodes N1-N23, a plurality of wireless sensor nodes N1-N4 and N20-N23 with which an originator computer PC1 and a destination computer PC2 can directly communicate are disposed as base station wireless sensor nodes. The originator computer divides transmission data and assigns and sends the divided data to the base station wireless sensor nodes. The wireless sensor nodes selectively form a plurality of communication paths for relaying the transmission data to the plurality of base station wireless sensor nodes. The destination computer integrates the data received from the base station wireless sensor nodes to restore it to the original data. COPYRIGHT: (C)2009,JPO&INPIT |
