Abstract
In this paper, we study distributed scheduling with different delay constraints for each user in a heterogeneous collaborative network with multiple relays, and the relay assists transmission under AF mode and DF mode, respectively. Considering the case that the winner source has full CSI, that is, the winner source in a contention has CSI of links from itself to relays and from relays to its destination. After research, it is found that this is a pure threshold strategy. In it, the threshold selection of each user is regarded as a non-cooperative game, and the existence of Nash equilibrium is proved. This paper maximizes the throughput by using the optimal stopping theory, and validates the correctness through numerical and simulation results.
