Abstract: An interactive synchronous technology for the wireless self-organized network is proposed, which is convenient for the network to adopt the Multiple Access Control(MAC) protocol based on Time Division Multiplex Address(TDMA) to meet the requirement of real-time traffic. The synchronization of the network is achieved by the exchange and interaction control of the time benchmark between the nodes. In this kind of synchronous technology, each node sends its time benchmark periodically. Any node should adjust its own time benchmark according to the time benchmarks of its neighbor nodes, so all the nodes in the network have the same time benchmark and realize the synchronization between them is achieved. It is indicated that this synchronous method neither needs any high precision clock for each node, nor depends on the other networks operation (such as GPS, etc.). On the other hand, this technology also avoids the bottleneck effect which will occur when the network's time benchmark is provided by a given node, and improves the network's reliability.
