标题: Relay Selection in Wireless Networks: Enhancing Communication Reliability and Efficiency In modern wireless communication systems, the growing demand for high-speed and reliable data transmission has highlighted the importance of cooperative communication strategies. One such strategy, known as Relay Selection, has emerged as a critical method for improving network performance, particularly in environments prone to signal fading, interference, and coverage limitations. Relay Selection refers to the process of intelligently choosing one or more intermediate nodes, called relays, to assist in transmitting information from a source to a destination, ensuring that communication remains robust and efficient.
