Time synchronization protocol for Ad Hoc network based on delay-probing

The MAC protocol based on reservation and dynamic-slot distribution can offer fine QoS guarantee for real-time traffic. One of its key technologies is how to realize the synchronism among the nodes. Therefore, a new time synchronization protocol for Ad Hoc network by means of delay-probing was put forward, which combined the merits of DMTS protocol and TPSN protocol. Through transmitting and relaying a little probing code, the protocol could complete the retardation measuring. Owing to the separation between delay-probing course and time-correcting course, the conflict and burden of the network could be lightened. Analysis and simulation indicate that DMC-TS protocol is simple to realize, and possesses a precision which can be compared with TPSN protocol.
