Claim:
1. A wireless communication apparatus comprising: a memory configured to store therein a first destination as a specified destination to which metering data is to be sent, and to store each piece of path information on a plurality of destinations including the first destination by associating with a path timer which counts down an elapsed time showing a use frequency of the path information; and a processor connected to the memory wherein the processor executes a process comprising: sending, when a request frame requesting the metering data destined for the wireless communication apparatus is received from the first destination, the metering data to the first destination and updating the path timer to an initial value, the path timer being in association with first path information on the first destination; setting, when a request frame requesting the metering data destined for the wireless communication apparatus is received from a second destination different from the first destination, the second destination as the specified destination and determining whether second path information on the second destination is stored in the memory; upon determination that the second path information is stored in the memory, updating the path timer associated with the second destination to the initial value; upon determination that the second path information is not stored in the memory, determining whether the memory has free space; and upon determination that the memory has free space, storing the second path information in the memory, and upon determination that the memory has no free space, deleting among the path information stored in the memory, path information indicating the path timer with a smallest value.
