Abstract
A communication apparatus includes an acquiring unit that acquires wireless cost for each path to other communication apparatuses in an ad hoc network to which the communication apparatus belongs; an accumulating unit that accumulates wireless cost for each path, acquired at different times by the acquiring unit; a determining unit that determines a priority level for each path, based on time correlations among the paths in terms of the wireless cost accumulated by the accumulating unit; and a communicating unit that communicates with the other communication apparatuses by preferentially using a path of a relatively high priority level.
Claims5
A communication apparatus comprising:
- an acquiring unit that acquires wireless cost for each path to other communication apparatuses in an ad hoc network to which the communication apparatus belongs;
- an accumulating unit that accumulates wireless cost for each path, acquired at different times by the acquiring unit;
- a determining unit that determines a priority level for each path, based on time correlations among the paths in terms of the wireless cost accumulated by the accumulating unit;
- and
- a communicating unit that communicates with the other communication apparatuses by using a path according to descending order of priority level;
- wherein the determining unit provides a path that has not been given a priority level and has the lowest time correlation with a path whose priority level has been determined with the highest priority level next to the priority level that has been determined.
A communication method comprising:
- acquiring wireless cost for each path to other communication apparatuses in an ad hoc network to which a given communication apparatus belongs;
- accumulating wireless cost for each path, acquired at different times at the acquiring;
- determining a priority level for each path, based on time correlations among the paths in terms of the wireless cost accumulated at the accumulating;
- and
- communicating with the other communication apparatuses by using a path according to descending order of priority level;
- wherein the determining provides a path that has not been given a priority level and has the lowest time correlation with a path whose priority level has been determined with the highest priority level next to the priority level that has been determined.
