System and method for dynamic formation of a communication network using wireless communication devices
A short-range wireless communication network may be established by direct communication between two or more wireless communication devices. A conventional cellular telephone includes an integrated short-range transceiver. The short-range transceivers of multiple wireless communication devices can be coupled together to form a short-range communication network without utilizing any wireless communication network supported by wireless service providers. The short-range communication network may be extended as additional devices come within range or consolidated as wireless communication devices leave the communication range. The short-range communication network is built upon the proximity of wireless communication devices with each other. Data is disseminated between the wireless communication devices using a data message synchronization process. Messages may also be carried from one wireless network to another as the communication devices are carried by individuals.
