In recent years, mobile devices such as mobile phones, smartphones and hand-helds are becoming more and more prevalent. With the emergence of smartphones, the availability of advanced localization technologies, like the global positioning system (GPS), increased significantly. This in turn enables the widespread and often continuous use of location based services to deliver tailored information...

Abstract- Communication has become inevitably part of our day to day activities, in academic, business, banking, and other sectors. It has therefore become so important to implement good and efficient communication system. A reference point according to this research is the wireless sensor networking (WSN) system, and most important thing in communication is to be free from interference, attenu...
