Wireless Sensor Network : A Survey

Abstract: Wireless Sensor Network the existing cluster based technique may result in increased network works.             WSNs are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. Sensor networks can contain hundreds or thousands of sensing nodes. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance; Networks are used in many industrial and applications, such as industrial process and control, machine health monitoring.
