Wireless ad-hoc communication system and communication terminal synchronizing method in wireless ad-hoc communication system
First Claim
1. A wireless ad-hoc communication system for transmitting/receiving beacons between a plurality of communication terminals to synchronize the communication terminals, comprising:
- a first network to which first subset of the plurality of communication terminals belong;
a second network to which second subset of the plurality of communication terminals belong; and
one or more synchronizing terminals capable of transmitting/receiving the beacon to/from the communication terminals, wherein at least one of the communication terminals belonging to the first network and at least one of the communication terminals belonging to the second network exist within a reachable range of the beacons from one of the one or more synchronizing terminals to construct one synchronized network with the first network, the second network, and the synchronizing terminals.

Abstract
In a wireless ad-hoc communication system according to an embodiment of the invention, a plurality of communication terminals transmit/receive beacons and are synchronized. The wireless ad-hoc communication system includes first and second networks each including one or more communication terminals; and one or more synchronizing terminals. The synchronizing terminals are capable of transmitting/receiving the beacons to/from the communication terminals. In the wireless ad-hoc communication system, at least one of the communication terminals belonging to the first network and at least one of the communication terminals belonging to the second network exist within a reachable range of the beacons from one of the one or more synchronizing terminals to construct one synchronized network with the first network, the second network, and the synchronizing terminals.
