Abstract:
The resource management problems in wireless networks are difficult since they involve complex competitions and selfish behaviors from participants. The competition effect and selfishness of participants in wireless networks imposes a serious threat to all existing solutions which assume that all participants will faithfully follow the orders of the system for some global objective. We notice that such an issue also exists in a centralized-control network as long as the control mechanism relies on the feedbacks from selfish participants. Game theory is suitable for analyzing resource management problems in wireless networks. It can help analyze, predict, and regulate the selfish behaviors of participants in wireless networks. We demonstrate how game theory can help regulate selfish behaviors in a centralized-control network in heterogeneous network and D2D communications. In heterogeneous networks, we propose a truthful auction with a greedy resource allocation algorithm in order to guarantee that all rational UEs truthfully report their QoS requirements. In a D2D communication system, we observe that the ad-hoc characteristic of D2D communication also poses the truth-telling issue into the system, we propose a Trader-assisted Resource Exchange (T-REX) mechanism, an exchange-based mechanism that converges in polynomial time, achieves Pareto optimal, and guarantees strategy-proofness.
