Abstract:
1. A communication device capable of communicating with a plurality of the other communication devices in different communication modes, the communication device comprising: a unit that measures performances of a communication between the communication device and one of the other communication device in each of the different communication modes, under the different communication data sizes respectively, for each of the other communication devices; a unit that determines, for each of the other communication device, a communication data size that a communication performance of a communication between the other communication device in a first communication mode exceeds a communication performance of communication in a second communication mode and set the determined communication data size as a threshold for the other communication device; and a unit that selects one of the communication modes that the corresponding communication performance exceeds the communication performance of the other communication mode in an actual communication under a particular communication data size between a particular communication device under a particular communication condition.
