Routing Protocols for D2D Communications with Adaptive Transmit Power

摘要

In this article, we suggest routing protocols for device-to-device (D2D) communications with relays using an adaptive transmit power. The generated interference by D2D nodes to cellular base station is lower than interference threshold T. Optimal routing consists of activating the path with the highest end-to-end signal to interference plus noise ratio. One-hop routing selects the best relay at each hop. Suboptimal routing decomposes the network in many subnetworks where the best path in each subnetwork is activated.
