Cooperative communication is a research area in wireless communications that focuses on improving the efficiency and reliability of communication systems by enabling devices to work together to transmit and receive data. This approach involves multiple nodes in the network sharing information and resources to enhance the overall performance of the communication system. By cooperating with each other, devices can overcome obstacles such as signal interference, limited bandwidth, and poor signal quality to achieve better communication reliability and coverage. Research in cooperative communication includes the development of cooperative protocols, strategies for resource allocation, and optimization techniques to maximize the benefits of collaboration among network nodes.
