Wireless Sensor Network: An Overview
Kushal Pradhan, Meghna Shinde · International journal of advanced research in computer science and electronics engineering · 2012
Wireless Sensor network are dense wireless networks of small, low-cost sensors, which collect disseminate environment data. Wireless sensors networks facilitate monitoring and controlling of physical environments from remote locations with better accuracy. They have applications in a variety of fields such as environmental monitoring , military purpose and gathering sensing information inhospitable locations. Sensor nodes have various energy and computational constraints because of their inexpensive nature and ad-hoc method of deployment. Considerable research has been focused at overcoming these deficiencies through more energy efficient routing, localization algorithms and system design. Our survey attempts to provide an overview of these issues as well as the solutions proposed in recent research literature.
