Mobile Cloud based architecture for Device-to-Device (D2D) communication underlying cellular network

Device-to-Device communication (D2D) allows User Equipment´s (UE´s) in the close vicinity to communicate directly by exploiting the cellular resources. The benefit of such communication paradigm results in an increase bit rate. Mobile Cloud (MC) is D2D based architecture of closely located multi-standard wireless devices connected to the cellular network as well as with each other through short-range links. In this way, MC assists other UE´s in the network for data delivery. Traditionally, a Cluster Head (CH) is employed for such MC based architectures. The homogeneous data distribution in to such network has many challenges such as, the selection of the best possible CH. This paper presents a novel architecture of MC where UE´s compete for Cluster Heads (CH´s) based on the residual energy and Signal to Interference and Noise (SINR). The proposed architecture comprises of multiple logical regions (clusters) having multiple CH´s. Simulation results shows about 25% increase in throughput and bandwidth efficiency as compared to classical mobile communication.
