In this paper, we propose a radio resource scheduling algorithm for a scheduler in IEEE 802.16 orthogonal frequency division multiple access (OFDMA) specification. The scheduler dynamically allocates slots considering wireless channel conditions of subscriber stations to improve radio resource utilization efficiency. The results show that with the proposed algorithm, smaller radio resources are used...
We consider the channel and power allocation problem for 802.11b public wireless access networks. We demonstrate exact that joint channel and power optimization is feasible for up to about 30 access points and that worthwhile performance gains can be achieved. We discuss various issues related to the structure of the optimization problem and its efficient solution.
We consider the problem of allocating resources (time slots, frequency, power, etc.) at a base station to many competing flows, where each flow is intended for a different receiver. The channel conditions may be time-varying and different for different receivers. It is well-known that appropriately chosen queue-length based policies are throughput-optimal while other policies based on the estimation...
