%X Wireless sensor network is a hot spot in current research, and event-driven data gathering is an important way of information collection for wireless sensor network. The nodes in the network just have limited energy and their communication abilities are weak. Moreover, the nodes are easy to be broken. However, users often need the network can provide long time or low delay services. Therefore, how to gather all data in the network with a way of low energy consumption, low delay and high reliability, is a difficult problem. This paper introduced the concepts and features of the event-driven data gathering, and gave systematic analysis and comparison on existing typical protocols. By discussing challenges and key problems in event-driven data gathering, the next research orientation will be found.
