Abstract: In order to decrease the complexity of popular distributed time synchronization algorithms for subnet merge in ad hoc networks, a new method based on the number and ID of node in subnet was proposed. When two subnets with synchronization difference are close to each other, the method firstly judges the priority of subnets according to the number and ID of node in subnets, and then makes the lower priority subnet synchronize with the higher priority subnet by listening to the time information of the latter. Performance analysis show that the method is better than the popular methods in time overhead and loss of packet because it can ensure the less number of node in lower priority subnet than that in higher priority subnet.
