A SURVEY ON WIRELESS SENSOR NETWORKS

A Wireless Sensor Network (WSN) can communicate the information through wireless devices. WSN consists of base stations and wireless sensor nodes. These networks are used to monitor various condition are sound, pressure, temperature and cooperatively pass data through the network to the main location. The functionality parameters of a sensor are energy consumption, computational speed rate, bandwidth, memory. In this paper, it embraces application of WSN, types of WSN, security issues and security mechanism.
