Practical service level agreement negotiation scheme for multicast service in WiMAX

Abstract

For multicast service in WiMAX, there are trade-offs between overall channel efficiency and the number of users under the commitment of service level agreements (SLAs). So, it is important to compromise between accommodating many users under the commitment of SLA and channel efficiency. In order to give an insight of multicast efficiency, we suggest a novel metric which is named as channel efficiency (MCE) factor. In addition, we proposed the practical SLA negotiation scheme based on proposed novel metric. Numerical results show that the proposed practical scheme significantly outperforms the conventional multicast transmission scheme.
