COMMUNICATION SYSTEM AND COMMUNICATION METHOD

摘要

A communication system according to an embodiment is provided with a plurality of communication apparatuses that sequentially transmit shared data by use of radio communications. Each of the plurality of communication apparatuses is provided with: a shared memory that can store shared data of each of the plurality of communication apparatuses; a transmission processing unit that transmits the shared data of the communication apparatus stored in the shared memory to a second communication apparatus that is another communication apparatus; a reception processing unit that monitors data which are the shared data received by the second communication apparatus from the communication apparatus and then transferred to a third communication apparatus that is another communication apparatus other than the second communication apparatus, and that receives the data as monitored data; and a data comparison unit that compares the received monitored data with the data immediately previously transmitted to the second communication apparatus.
