Abstract

The demand of media delivery services has increased with the popularity of social media and with the evolution of the user’s devices (i.e., smartphones, laptops, and tablets) pushing towards new contents distribution models. The coexistence of go-live and on-demand media content requires a combined broadcast/unicast delivery model with the efficient management of the wireless access as a key issue. A twofold target needs to be reached: optimizing the load balance among coexisting networks and offering adequate quality of service (QoS) to users. To achieve this target for mobile video service delivery over heterogeneous networks (HetNet) scenarios, this paper proposes a solution based on an additive logarithmic weighting (ALOW) algorithm combining received signal power, network load, packet delay, user’s equipment, and user’s credit budget. ALOW is optimized by means of a cooperative game theory (GATH) approach. The proposed solution, named ALOWGATH (i.e., ALOW + GATH), has been tested on realistic HetNet scenarios and compared to the state of the art of the network selection and balancing algorithms. Results show an improved performance in terms of throughput, satisfaction index and overall video quality delivered, with reduced computational complexity. [ABSTRACT FROM AUTHOR]

2. Adaptive multicast scheduling for HSDPA networks in mobile scenarios.

Author

Araniti, G., Condoluci, M., and Iera, A.

Abstract

This paper addresses the design of an innovative scheduling algorithm which optimizes the performance of Multimedia Broadcast Multicast Service (MBMS) in High Speed Packet Access (HSPA) networks. The proposed policy is based on the subgrouping approach which splits multicast members into subgroups and applies a subgroup-based Adaptive Modulation and Coding mechanism. The optimal number of multicast subgroups with the assigned radio resources is evaluated by solving an optimization problem. The robustness of the proposed approach has been investigated under different pedestrian mobility scenarios. Obtained results demonstrated that user mobility does not meaningfully influence the performance of our policy which allows to minimize the “user dissatisfaction” while increasing the network coverage.

3. Video Tester — A multiple-metric framework for video quality assessment over IP networks.

Author

Ucar, Inaki, Navarro-Ortiz, Jorge, Ameigeiras, Pablo, and Lopez-Soler, Juan M.

Abstract

This paper presents an extensible and reusable framework which addresses the problem of video quality assessment over IP networks. The proposed tool (referred to as Video-Tester) supports raw uncompressed video encoding and decoding. It also includes different video over IP transmission methods (i.e.: RTP over UDP unicast and multicast, as well as RTP over TCP). In addition, it is furnished with a rich set of offline analysis capabilities. Video-Tester analysis includes QoS and bitstream parameters estimation (i.e.: bandwidth, packet inter-arrival time, jitter and loss rate, as well as GOP size and I-frame loss rate). Our design facilitates the integration of virtually any existing video quality metric thanks to the adopted Python-based modular approach. Video-Tester currently provides PSNR, SSIM, ITU-T G.1070 video quality metric, DIV and PSNR-based MOS estimations. In order to promote its use and extension, Video-Tester is open and publicly available. [ABSTRACT FROM PUBLISHER]

Abstract

In this paper an innovative Radio Resource Management (RRM) algorithm is proposed with the purpose of increasing High Speed Packet Access (HSPA) performances, in terms of system capacity and service quality, when the Multimedia Broadcast Multicast Services (MBMS) is supplied. The proposed RRM algorithm exploits channel quality indications to set up point-to-multipoint connections to subgroups of multicast users and to select the proper modulation and coding schemes on the downlink. The number of subgroups is determined through an optimization technique that also takes into account the user satisfaction. An exhaustive simulation campaign is conducted to compare the proposed algorithm with the most promising approaches in the literature. Comparisons aim to assess the capability of the proposed RRM algorithm to efficiently manage group oriented services by providing an increment in terms of user satisfaction., Comment: Broadband Multimedia Systems and Broadcasting (BMSB), 2011 IEEE International Symposium on
