Title:
無線端末
Document Type and Number:
Japanese Patent JP4037640
Kind Code:
B2
Abstract:
A wireless terminal capable of quickly searching for the best route required for communication in a local network such as an ad hoc network is provided. Each of wireless terminals in the local network sets a bit error rates and a data transfer rate with neighboring wireless terminals and, based on the calculated values, calculates the route weight value of a link to each of the neighboring terminals. To set a route for communication between a wireless terminal and another wireless terminal, the wireless terminal issues a route search command based on the route weight value and sends the route weight value to neighboring terminals. The neighboring terminals also send the route search command sequentially to the next terminal while adding up the route weight value. A wireless terminal at the other end decides the best route from the added up route weight value and sends a response back to the starting point.
