ABSTRACT

Wireless networks are increasing at a tremendous rate in the current era and becoming essential for information sharing. With the expansion in the activities requiring internet connectivity, the growth in the number of connected devices and the demand for coverage extension of network connectivity, different techniques to improve capacity and coverage in wireless networks has emerged. Cooperative communication is one of the advanced techniques that have emerged as a promising paradigm to enhance not just coverage and capacity but also reliability and spectral efficiency of wireless communication systems. This paper presents a comprehensive review of the advancements in cooperative communication techniques, challenges, and future directions. The areas covered include; an overview of the fundamental principles and benefits of cooperative communication; various cooperative communication techniques, including relay selection, power allocation, and coding schemes, highlighting their advantages and limitations; key challenges in implementing cooperative communication, such as synchronization, channel estimation, and relay selection criteria; the impact of practical considerations, such as hardware constraints and network topology; and the future research directions, including the integration of cooperative communication with emerging technologies such as machine learning and blockchain. This review provides researchers and practitioners with a comprehensive understanding of the state-of-the-art in cooperative communication and inspires new avenues for research and development in this field.
