Abstract
Device-to-device (D2D) communication is a key technology in next-generation wireless networks to enhance spectrum resource utilization. The interference from the activated D2D links degrades the quality of service (QoS) provided to cellular users. In this work, we propose a location-based technique to tackle the interference caused by the D2D underlaying downlink cellular network. The devices operating in stationary and mobile modes are considered, with mobile devices modelled using a Gauss Markov mobility (GMM) model to simulate realistic user movement patterns. Initially, we present an interference mitigation approach that dynamically adjusts the guard zone (GZ) through power control to guarantee the required QoS for all users. A distance-based mode selection mechanism is proposed to enable the users to select their mode of communication based on different GZ regions. Furthermore, we derive the closed-form expressions of the average coverage probability for the cellular and D2D links under the proposed power control with guard zone (PC-GZ) scheme. Finally, extensive simulations confirm the efficacy of the proposed PC-GZ approach, illustrating a 15% increase in cellular coverage probability compared to the PC-ILA scheme in high D2D density scenarios.
期刊介绍：
The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
