Description
Summary:A two-tier heterogeneous network, comprised of a macrocell underlaid with flexible and uncoordinated femtocell network, provides an economically viable way to improve indoor coverage, users' QoS and the capacity of the whole cellular network. However, mutual interference between macrocell and femtocell limits capacity and leads to the problem of coexistence. This paper proposes a game theoretical and decentralized spectrum negotiation framework to solve the above-mentioned problem. Macrocell and femtocell users have to reach a mutual satisfactory agreement on the partition of spectrum by making alternating offers to each other. By modeling the bargaining process as multi-stage dynamic game, we are able to obtain the equilibrium outcome. Theoretical and numerical analysis on negotiation results show that macrocell and femtocell can achieve a fair, efficient, and incentive compatible spectrum allocation via the proposed bilateral negotiation interactions.
