1. A wireless device which is used in a mesh network including a plurality of wireless devices located in a mesh pattern, and makes wireless communication using a plurality of channels, the device comprising:

  • a routing table storing route information;

    a plurality of interfaces each of which transmits and receives a packet using one channel selected from among the plurality of channels;

    a tabulation unit creating the routing table by detecting a route with relatively large ratio of throughput to maximum throughput, considering channel interference in flows, and excluding loop routes, and storing the detected route as the optimum route to a destination; and

    a communication unit selecting the optimum route from the routing table and transmits a packet,wherein the tabulation unit stores, in the routing table, a route metric which is smaller when the ratio of throughput to maximum throughput is larger, and larger when the ratio of throughput to maximum throughput is smaller, and a destination corresponding to the route metric to indicate the optimum route.
