A REVIEW ON WIRELESS SENSOR NETWORK

The wireless sensor network technology are used in different fields and for different purposes such as health care monitoring, environmental and biological monitoring. By the above application the problem may arise when it is not handled properly. The major areas of research in WNS are on hardware, architecture, localization, programming models, data aggregation and quality of service. The impact of WSN on our day today life is relatively compared to what internet has done to us. This paper shows the ongoing research activities and issues that affect the WSN performance and design.
