“…When the number of group members increases, the complexity of the scheme also increases significantly. An utility-based resource allocation scheme is developed for layer-encoded multicast transmissions in [18], where the number of transmission layers is adjusted according to the channel conditions, available network resource, and the utility contribution of each layer. How to properly define a utility function for video stream is still an open issue.…”

Abstract-Multicast communications is an efficient mechanism for one-to-many transmissions over a broadcast wireless channel, and is considered as a key technology for supporting emerging broadband multimedia services in the next generation wireless networks, such as Internet Protocol Television (IPTV), mobile TV, etc. Therefore, it is critical to design efficient multicast scheduling schemes to support these multimedia services. In this paper, we propose a cooperative multicast scheduling scheme for achieving efficient and reliable multicast transmission in IEEE 802.16 based wireless metropolitan area networks (WMAN). By exploiting the multi-channel diversity across different multicast groups and user cooperation among group members, the proposed scheme can achieve higher throughput than existing multicast schemes, for subscriber stations in both good and bad channel conditions. In addition, it has good fairness performance by considering the normalized relative channel condition of each multicast group. An analytical model is developed to evaluate the performance of the proposed scheme, in terms of service probability, power consumption, and throughput of each group member and multicast groups. The efficiency of the proposed scheme and the accuracy of the analytical model are corroborated by extensive simulations.Index Terms-Cooperative communication, multicast scheduling, IEEE 802.16.

“…Several works in the literature address the problem of the efficient delivery of multimedia streaming content to different multicast groups simultaneously when served by a given BS [14], [15], [16], [17]. Such works consider multi-layer services where each video stream (or program) is encoded into different layers.…”

“…The authors of [14] focus on finding a utility-based resource allocation scheme for layer-encoded IPTV multicast streaming services over IEEE 802.16 WiMAX networks. Besides, they prove that the problem of finding the best subset of users to serve per each layer for each multicast group is NP-hard, and propose an approach that can run in polynomial time.…”

“…Besides, they prove that the problem of finding the best subset of users to serve per each layer for each multicast group is NP-hard, and propose an approach that can run in polynomial time. The works reported in [15] and [16] follow an approach similar to that described in [14], by proposing near-optimal algorithms for subgroup management. In particular, authors in [15] present a fast greedy algorithm aimed at achieving a proportional fair resource allocation, which is probably within a constant approximation of the optimal solution (based on a metric that reflects video quality as perceived by the user according to the data rate experienced by the multicast members).…”

Abstract-Recently, mobile multimedia services have represented an increasingly large source of revenue for the telecommunication industry. Subscribers are often interested in simultaneously receiving the same data flow and, hence, they fuel the growing demand of multicast multimedia services. Therefore, the design of efficient radio resource management strategies to jointly handle multicast and more traditional unicast traffic and to increase user satisfaction is of primary importance for the successful deployment of future mobile networks. This paper proposes an efficient radio resource management framework to handle unicast and multicast multi-layer video services. The proposed Virtual Unified Group (VUG) approach makes use of a channel-aware subgrouping principle to provide fair throughput to both unicast and multicast users. The idea is to assign unicast subscribers to a virtual group thus allowing them to compete for network resources on an equal footing with multicast users. Simulations highlight the benefits that VUG provides in a Long Term Evolution (LTE) network scenario, under different traffic load conditions, in terms of throughput and fairness in the distribution of resources to unicast and multicast users.

The goal of Resource Allocation Scheme (RAS) is to accomplish maximum usage of resources, assures Quality of Service (QoS), exploit throughput and diminish power consumption with viable algorithm complexity and scalability of system. RA algorithm for dynamic RAS in downlink Mobile WiMAX is to maximize the minimum rate of user while satisfying power constraint. This study emphasizes on scalable video transmission in Downlink Mobile WiMax BS with 5 WLAN's each comprised of 10 users with different QoS requirements. Convex optimization techniques in scheduling algorithms marginally improve the performance measure as compared to traditional iterative non-linear methods. This study proposes Active-Set optimization technique for power allocation (PA) amongst subcarrier per Subscriber Station (SS) and Greedy Weighted Algorithm (GWA) for sub-carrier allocation. Finally simulation results show that the proposed GWA and Active-Set optimization technique can effectively achieve maximum network throughput and number of satisfied users.
