Challenges of Wireless Sensor Network

Abstract

This paper describe the Wireless Sensor Network (WSN) is the current research field in computer science & has growing use in day to day life. As a new technology, it has several research challenges and vast opportunities for the researchers. A wireless sensor network (WSN) consists of a large number of sensor nodes which are deployed over an area to perform local computations based on information gathered from the surroundings. The survey main techniques used for energy conservation in sensor networks. Different applications by wireless sensors for healthcare and energy saving system are discussed. This paper highlights WSN, its architecture, challenges, applications and classification of various protocols concerning it. It also classifies various security protocols to make WSN a secure network.
