The technological advancement has increased the demand for different kind of multimedia traffic and energyconsuming applications and therefore posing new challenges for network operators to cope up with the current and future requirements. The three characteristic challenges faced by network operators are enhanced system throughput, dynamic environment adaptability and productive utilization of the available resources. While substantial amount of work has been done in this context, particularly on cooperative and cognitive networks, the very approach has certain limitations and shortcomings. In this respect, D2D (Device-to-Device) communication offers promising gains such as cellular data offloading, energy savings and bandwidth efficiency. D2D also offers efficient distribution of popular content in short range. Here we propose Mobile Cloud (MC), a novel yet simplistic system architecture that employs cognitive and cooperative strategies to address the above mentioned challenges. The system exploits short-range links to establish a smart social network among the nearby devices adapts according to environment and uses various cooperation strategies to obtain efficient utilization of resources. In this work, we demonstrate the practical implementation of a self-organizing MC that is formed by a group of devices themselves in close proximity by exploring short-range links. We also propose and implement different content distribution techniques for our MC based testbed. Furthermore, we also compare and present practical results for different content distribution techniques in terms of system throughput.
