Abstract
In this paper service differentiation is provided through user-centric distributed non-cooperative multilateral bargaining for resource allocation in the uplink of multi-service SC-FDMA wireless network. Initially, a well-designed utility function is formulated to appropriately represent users’ diverse QoS prerequisites with respect to their requested service. The subcarriers allocation problem is solved based on a multilateral bargaining model, where users are able to select different discount factors to enter the bargaining game, thus better expressing their different needs in system resources. The subcarriers mapping is realized based on the localized SC-FDMA method where the subcarriers are sequentially allocated to the users. Given the subcarriers assignment, an optimization problem with respect to users’ uplink transmission power is formulated and solved, in order to determine the optimal power allocation per subcarrier assigned to each user. Finally, the performance of the proposed framework is evaluated via modeling and simulation and extensive numerical results are presented.
