Abstract:
1. A wireless terminal comprising: weight value setting means for dynamically setting a weight value of communication paths based on a communication status for each of a plurality of communication paths, each having one end connected to a neighboring other terminal, said weight value of the communication paths being a reference value for selection when communication is performed over the communication paths; route search request relaying means, on receipt of a route search request from another terminal different from the wireless terminal of communication source, said route search request issued for establishing a communication route to a predetermined terminal as a communication destination, with the weight value of the communication paths, through which said route search request has passed, attached thereto, sending to a predetermined communication path the route search request with a weight value of the communication path attached thereto, said predetermined communication path being selected from among communication paths beginning at the wireless terminal of communication source and being connected to the wireless terminal of neighbor based on the weight values of the communication paths; route deciding means, on receipt of the route search request specifying the wireless terminal as a communication destination, deciding a best route based on the weight value of the communication paths through which the route search request has passed, said weight value being attached to the route search request; and route search result notifying means for notifying the route decided by said route deciding means to a source terminal of the route search request.
