标题: Efficient Relay Selection Strategies in Modern Wireless Networks In modern wireless communication networks, the concept of relay selection has become an essential mechanism for enhancing signal quality, extending coverage, and improving overall system performance. Relay selection refers to the process of identifying and choosing the most suitable intermediate node—or relay—to forward information between a source and a destination. This approach is particularly significant in cooperative communication systems, where multiple nodes can collaborate to transmit data more reliably and efficiently.
