APPLICATIONS OF WIRELESS SENSOR NETWORKS: AN OVERVIEW

A wireless sensor network is a type of wireless network consist a collection of tiny device called sensor node. Sensor node has a resource constraint means battery power, storage and communication capability. These sensor nodes are set with radio interface with which they c ommunicated with one another to form a network. Wireless sensor network has very necessary application like remote has remote environmental monitoring and target tracking. The goal of our survey is to present a comprehensive review of the recent literature on various aspects of WSN and also discuss how wireless sensor network works and advantages and disadvantages over the traditional network. Wireless Sensor Networks are networks composed of a number of sensor nodes that communicate wirelessly. It's utiliz ed over a wide range of applications. This paper looks at the Wireless Sensor Networks from the applications point of view and surveyed different application areas where the use of such sensor networks and their specifications, capabilities.
