Modeling of MTC Energy Consumption for D2D communications with Chase Combining HARQ Scheme

Abstract : Device-to-Device (D2D) communication for Massive Machine-Type Communication (mMTC) applications is a promising approach to reduce the energy consumption of the battery-limited Machine-Type Devices (MTDs) located in poor coverage areas. In this paper, we analyze the energy consumption of the MTDs when Automatic Repeat reQuest (ARQ) and Hybrid ARQ with Chase Combining (CC-HARQ) mechanisms are used to improve the reliability of D2D communication. By using the tools of stochastic geometry, we derive analytical expressions for the system success probability, the average number of transmissions, and the average MTD energy consumption. Numerical results show that CC-HARQ mechanism outperforms ARQ mechanism in terms of energy consumption, especially when the distance between an MTD and its relay increases (at low relay density) or when the density of MTDs sharing the same sub-channel increases.
