Wireless Sensor Networks: Applications and Issues

Abstract

In today’s scenario, wireless sensor network is one of the most important technologies used. Wireless communications and electronics are now available in low cost, consume less power and provide multifunctional miniature devices which are beneficial for use in remote sensing applications. These factors have improved the viability of utilizing a sensor network consisting of a large number of intelligent sensors, enabling the collection, processing analysis and dissemination of valuable information gathered in a variety of environments. A sensor network is composed of a large number of sensor nodes which consist of sensing, data processing and communication capabilities.
