Abstract
A communication device transmits data through a communication bus. The communication device includes a processing unit that performs processing. When a beacon signal is transmitted, the processing unit determines whether or not a target communication device included in a plurality of second communication devices has transmitted data at a timing at which the target communication device transmits one of data pieces transmitted through the communication bus according to an order set in advance by the communication device itself and the plurality of second communication devices. When it is determined that the target communication device has transmitted no data, the processing unit changes the order. The data transmitted through the communication bus includes dummy data whose transmission destination is different from communication devices other than a transmission source among the communication device itself and the plurality of second communication devices.
