摘要：Recent advancement in wireless communication and electronics has enabled the development of low cost sensor network. The sensor network can be used for various application areas like military, health, home. Wireless Sensor Network refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. WSNs measure environmental conditions like temperature, sound, pollution level, humidity, wind speed and direction, pressure etc. WSN is a group of specialized transducers with a communications infrastructure that uses radio to monitor and record the physical condition. WSN provide a bridge between the real physical and virtual world. It allows the ability to observe the previously unobservable at a fine resolution over large spatio- temporal scales. A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight, portable. Every sensor node is equipped with a transducer, microcomputer, transceiver and power source. A wireless sensor network is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. Commonly monitored parameters are temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels and vital body functions. A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight and portable. The WSN is an emerging technology in the field of communication. This technology has many advantages but the security issues have been not given much consideration till now.
