A two-user decision making game is studied in the OFDM based subscriber cooperative relaying network, in which subscribers transmit their own data in the first phase, while helping to retransmit their partner's or choosing to freeride in the second phase. In the paper, we study a hierarchical game (HG) for a two user coalition, where cooperation is preferred and total payoff is transferable. Instead...
Uplink resource allocation in OFDMA cellular networks enhanced with two-hop fixed relays is studied in this paper. A resource optimization problem that maximizes sum uplink throughput of all users is formulated under path selection and PHY/MAC constraints. The dual decomposition method is adopted to solve the problem efficiently and optimally. Dual problem of the primal problem is decoupled into N...
