Abstract: Because of the self-organization network structure,wireless sensor network (WSN) data gathering has enormous advantages compared with other networks.However,many key problems have  not been resolved in wireless sensor networks yet because of limited resources.In this paper,the key technology and main challenges in WSN data gathering are summarized,and the main performance index and research methods of WSN network protocols in data gathering are introduced.At the same time,several new technology combined with WSN are analyzed and discussed.In the end,the research direction in the future is prospected.

Key words: wireless sensor networks, summary, data gathering, MIMO
