Layer-encoded multimedia multicasting (LMM) has emerged in recent years to support heterogeneous subscriber stations with diverse computing and networking capabilities. With the advance of broadband wireless access technologies, wireless relay networks (WRNs) are expected to provide significant improvement on throughput and extension of coverage for next-generation wireless systems. In this paper,...
IEEE 802.16e and 802.20 are emerging as two promising technologies for broadband wireless access systems. In order to improve capacity and coverage performance, both of them addressed a fractional frequency reuse (FFR) scheme to combat co-channel interference in multi-cell deployment, which is referred to as FFR16 and FFR20 respectively in this paper. As for the scheme of FFR20, virtual area partition...
The IEEE 802.16 broadband wireless access (BWA) system offers a cost-effective solution to the last-mile wireless connection problem. To provide the necessary QoS guarantees to the multimedia traffic in BWA systems while utilizing the resources as efficiently as possible, optimal scheduling mechanisms and resource allocation strategies are needed. In this paper, we model the resource request and distribution...
