Abstract: Aiming at the latest development of the sensor, microprocessor and wireless communication technology, in order to intensive study the key technology of wireless sensor networks, the domestic and overseas research status of wireless sensor networks was analyzed on the basis of introducing the development history of the wireless sensor networks as well as system architecture. And the application of wireless sensor networks was disscussed in following fields, military, medical treatment and public health, environmental monitoring, smart home and so on. And the hot issues of the wireless sensor networks were also elaborated. The results indicate that the wireless sensor networks have been developing toward low cost, low energy consumption, intellectualization which has a certain reference value for carrying out relevant research.
