Wireless communication system

A control device for a wireless communication system that collects data generated from a plurality of moving entities, wherein the moving entities communicate among each other or with a relay via short-distance wireless communication by using a DTN (Delay Tolerant Network) which employs a store-carry-and-forward process, the control device comprising:

• a memory;
• and
• a processor which executes one or more programs stored in the memory to carry out operations comprising:
• generating and transmitting to the moving entities, via long-distance wireless communication, generation command data that instructs the moving entities to collect data and controls a condition of data forwarding between the moving entities;
• carrying out communication with the relay or with one of the moving entities, via wired communication or via the long-distance wireless communication, to obtain data that has been collected by the moving entities in response to the generation command data, the obtained data having been communicated among the moving entities or between at least one of the moving entities and the relay via the short-distance wireless communication by using the DTN (Delay Tolerant Network) which employs the store-carry-and-forward process.

A moving entity for a wireless communication system that collects data generated from a plurality of moving entities, the moving entity comprising:

• a memory;
• and
• a processor which executes one or more programs stored in the memory to carry out operations comprising:
• receiving, from a control device via long-distance wireless communication, generation command data that instructs the moving entity to collect data and controls a condition of data forwarding between the moving entities;
• collecting data in response to the generation command data;
• carrying out communication with another one of the moving entities or with a relay via short-distance wireless communication by using a DTN (Delay Tolerant Network) which employs a store-carry-and-forward process, to transmit or receive data that has been collected in response to the generation command data.

A wireless communication system that collects data generated from a plurality of moving entities, the wireless communication system comprising:

• a relay;
• a control device;
• and
• a plurality of moving entities which communicate among each other or with the relay via short-distance wireless communication by using a DTN (Delay Tolerant Network) which employs a store-carry-and-forward process;
• wherein the control device comprises a memory and a processor which executes one or more programs stored in the memory to carry out operations comprising:
• generating and transmitting to the moving entities, via long-distance wireless communication, generation command data that instructs the moving entities to collect data and controls a condition of data forwarding between the moving entities;
• carrying out communication with the relay or with one of the moving entities, via wired communication or via the long-distance wireless communication, to obtain data that has been collected by the moving entities in response to the generation command data, the obtained data having been communicated among the moving entities or between at least one of the moving entities and the relay via the short-distance wireless communication by using the DTN (Delay Tolerant Network) which employs the store-carry-and-forward process.
