Repeated Game Based Cooperation Mechanism for Antenna Beam Resource Allocation in TDRSS

In the tracking and data relay satellite system, users compete for the limited inter-satellite link antenna beam (ILAB) resource by excessive resource requests. This can lead to serious user request conflicts and considerably degrade the QoS (quality of service) of the system. Since those selfish users have no incentive to cooperate in a one-shot resource request, in this paper we construct a cooperation mechanism to maximize users' payoffs and meanwhile to reduce the conflict relying on a repeated game framework. Moreover, an efficient punishment and forgiveness strategy is proposed to prevent any user from breaking the cooperation. Simulation results confirm that the proposed scheme can significantly improve the system's operation performance. Compared with the payoffs under the Nash equilibrium in the one-shot game which is the traditional scheme, our repeated ILAB resource allocation game can acquire 1.36 to 3.46 times gain in respect to 2 to 10 users, respectively.
