Performance Analysis of Traffic-Adaptive MAC Strategies for Mobile Device-to-Device Communications

摘要

Device-to-device (D2D) communication in both adhoc and cellular networks can provide efficient data transmission without additional infrastructure, and increase data throughput, spectrum usage, and energy efficiency. MAC protocols in D2D communication can efficiently schedule mobile users and allocate physical resources to multiple devices. Centralized MAC and peer-to-peer MAC in D2D can be designed for various traffic loads and density of devices. This paper analyzes the typical MAC approaches to improve data throughput, delay, and energy efficiency in D2D scenarios. The analytical evaluation and simulation results demonstrate the suitable MAC strategies for various traffic loads and mobile devices in D2D communication.
