Research on Wireless Sensor Network and Its Related Issue

Recent advances in sensor, micro-electro-mechanical systems(MEMS)technology,nested computation and wireless communications haveenabled the developmentof wireless sensor networks(WSNs)including alarge number sensor nodes, which consistint of sensing, data proeessing, and communieating components. Based on the organizational structure of wireless sensor networks, management techniques and theory of architecture, and analyzes its features. Analysis of a wireless sensor network security threats and propose effective solutions. The characteristics of wireless sensor networks, design efficient and secure wireless sensor networks is very challenging and practical significance of the work, the applications of wireless sensor networks will be more extensive.
