QoE-based packet dropper controllers for multimedia streaming in WiMAX networks

Abstract The proliferation of broadband wireless facilities, together with the demand for multimedia applications, are creating a wireless multimedia era. In this scenario, the key requirement is the delivery of multimedia content with Quality of Service (QoS) and Quality of Experience (QoE) support for thousands of users (and access networks) in broadband in the wireless systems of the next generation. This paper sets out new QoE-aware packet controller mechanisms to keep video streaming applications at an acceptable level of quality in Worldwide Interoperability for Microwave Access (WiMAX) networks. In periods of congestion, intelligent packet dropper mechanisms for IEEE 802.16 systems are triggered to drop packets in accordance with their impact on user perception, intra-frame dependence, Group of Pictures (GoP) and available wireless resources in service classes. The simulation results show that the proposed solutions reduce the impact of multimedia flows on the user's experience and optimize wireless network resources in periods of congestion. The benefits of the proposed schemes were evaluted in a simulated WiMAX QoS/QoE environment, by using the following well-known QoE metrics: Peak Signal-to-Noise Ratio (PSNR), Video Quality Metric (VQM), Structural Similarity Index (SSIM) and Mean Option Score (MOS).

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
