| Summary: | This work presents the Network Assisted Routing and Allocation Algorithm (NARA), a routing and allocation algorithm for
device-to-device (D2D) communication in 5G cellular architectures. NARA algorithm is a new routing and resource block
allocation algorithm that aims at reducing the impact of interference and extends network coverage in D2D communications.
We model the allocation of resource blocks as a Minimum Graph Coloring Problem. As baselines, we compare the proposed
strategy to NAR-G, a previous version that uses a greedy allocation heuristic; MaxC/I, a reference heuristic for resource
allocation; and LBS-AOMDV for routing. The results reveal that NARA reduces message loss in 47.4% when compared LBS-AOMDV,
39.87% to NAR-G, and 23.06% when compared to MaxC/I. As for allocation, NARA provides 23.05% more D2D flows than MaxC/I. |
