Abstract: Since the finitude of hardware and network dynamic limit the bandwidth in the wireless Internet of things ( IOF)，it is difficult to obtain the network topology information accurately and timely. Comprehensive,accurate and fast topology discovery has an important meaning to the network control, congestion control and fault location. In this pa- per,an improved fuzzy algorithm and strategy based on multi-mobile agent cooperative system were proposed. Our mo- del contains the process method of topology infom}ation, the agent active degree and migration, etc. We presented the best ration of agents to nodes and the IOF network topology algorithm As expected, the model is efficient and can save resources.
