Low-Overhead Multihop Device-to-Device Communications in Software Defined Wireless Networks

The growing massive number of user equipments (UE) is one issue that needs to be undertaken due to the development of Internet of Things. Device-to-device (D2D) communication and Software Defined Networks (SDN) are two promising technologies that can handle this challenge. Multihop D2D could be exploited as communication between devices while the routing is controlled via SDN. In this paper, we propose a wireless network architecture that exploits multihop D2D to provide effective and efficient communication between mobile devices in a network that are controlled via SDN techniques. We also propose five procedures for our proposed routing scheme, called low-overhead D2D routing (LODR). Several experiments are conducted to evaluate the performance of LODR. The simulation results show that the LODR produces less control overhead by 55% and faster convergence by 40% than previous work.
