The 3rd Generation Partnership Project (3GPP) working group has been instrumental in developing a successful wireless broadband technology in the form of the fourth generation long term evolution (4G LTE). The technology has been a major success with its penetration rate reaching over 75% in all developed countries. The working group is determined to release their fifth generation (5G) wireless standard...
Due to the simple technical implementation, lowcost network construction and high-bandwidth wireless link capacity, WiFi networks have become popular in the last decade. Nevertheless, WiFi networks have still facing various technical challenges such as load balancing, mobility support and channel adaptation. The emerging software defined networking (SDN) has now been proposed to address the above...
Software Defined Networking (SDN) is getting much attention for larger network implementation adding programmable feature in the network plane.

There is an increasing demand in designing heterogeneous networks, where various low-power wireless radios such as ZigBee and Bluetooth devices coexist, while sensing devices may generate traffic with different intervals. In this work, we devise an architecture of a cross layer controller, encompassing a software defined radio at the data plane to manage radio access, and a software defined networking...
Wireless networks for IoT applications support different types or classes of end devices. Each such class results in different uplink and downlink traffic behavior. It is important to identify suitable class for each end device. We first propose a generic framework for this purpose. We propose an element, called Software Controller, which learns device profile using variety of means such as information...

Nowadays, most mobile devices are equipped with multiple wireless interfaces, causing an emerging research interest in device to device (D2D) communication: the idea behind the D2D paradigm is to exploit the proper interface to directly communicate with another user, without traversing any network infrastructure. A first issue related to this paradigm is the need for a coordinator, called controller,...
Near Field Communication (NFC) is a set of very short range wireless technologies, typically requiring a distance of few centimetres to initiate connection. NFC allows sharing or exchange small payloads of data between two powered devices in a peer-to-peer fashion within pervasive computing and the Internet of Things environments. The NFC-based applications in the educational domain are still below...
