Network Management Model for Device-To-Device Communication in Ultra Dense Mobile Networks

This paper proposes a novel context-based network management model for device-to-device (D2D) communication in ultra dense mobile networks. Network management activities, such as bandwidth allocation, interference control, mobility management, resource management, and security management are addressed. To this end, a two-tier structure consisting of a context-aware device layer in the radio access network (RAN) and a centralized application layer is presented. The respective roles of these layers in the management model are discussed in detail. In particular, the context-aware device layer focuses on providing information regarding the application layer, while the application layer is responsible for monitoring of the overall D2D network. Additionally, a resource-efficient management scheme is proposed, based on the context-aware device layer, in order to optimize the bandwidth allocation in the D2D network. This kind of management model allows for the network to be used more effectively in ultra dense mobile systems, as it effectively offloads data traffic from classical cellular systems. Finally, the performance of the proposed network management model is evaluated through simulations.
