Abstract
A communication apparatus, comprises a forming unit configured to form a wireless network with another communication apparatus; and a control unit configured to control a start timing of data communication with the other communication apparatus based on role information of the communication apparatus in the wireless network.
Claims12
A communication apparatus, comprising:
- one or more processors;
- and
- one or more memories storing instructions that, when executed by the one or more processors, cause the communication apparatus to:
- obtain from another communication apparatus information relating to a service provided by the other communication apparatus, before forming a wireless network with the other communication apparatus;
- form the wireless network with the other communication apparatus, after the information is obtained;
- and
- delay, based on the obtained information, after addresses for performing a communication in the wireless network are assigned to the communication apparatus and the other communication apparatus, a start of data communication with the other communication apparatus, until an address overlap confirmation for confirming whether or not an IP (Internet Protocol) address of the other communication apparatus, which is provided by the communication apparatus, is overlapped in the wireless network is completed by the other communication apparatus.
