Reservation-based channel access in WLANs provides predictable and deterministic transmission and is therefore able to provide timeliness guarantees for wireless real-time applications. Reservation based channel access is energy-efficient since a wireless adaptor is powered on only during its exclusive channel access time. Keeping the bandwidth reservation of a node to a minimum leads to reduced energy and resource requirements and leaves more bandwidth reservation for other nodes. To obtain a solution to the efficient bandwidth allocation problem, the authors transform the generic task problem, which is then addressed using the scheduling policy algorithm.
