Wireless sensor network that has wide promise and potential with various applications has aroused the common interesting of academic researchers and industrial circle. Firstly, this paper has mainly described the characteristic and the content of congestion control in wireless sensor network. Then, a careful analysis of the implementation of the congestion control algorithm involves technical difficulties and deficiencies were made, and all kinds of classic algorithms were made to comparative study. At the same time, the status of existing work's research and development were sum up. Finally, the future research directions of congestion control of wireless sensor network that the research field is in the initial developing stage were pointed out.
