In the modern era, cellular communication consumers are exponentially increasing as they find the system more user-friendly. Due to enormous users and their numerous demands, it has become a mandate to make the best use of the limited radio resources that assures the highest standard of Quality of Service (QoS). To reach the guaranteed level of QoS for the maximum number of users, maximum utili...

A preliminary study is presented on a Software Defined Radio (SDR) receiver with the capability of receiving both the position information and the cellular services. In these last years, a great attention in wireless communication is devoted at integrating different standards into the same device in order to make a reconfigurable wireless terminal. In particular one of the most important topic ...

The allocation of web-based providers to users (brokering) is modelled by a strategic non-cooperative angel-daemon game w...
