Case Study in Assessing Subjective QoS of a Mobile Multimedia Web Service in a Real Multi-access Network

چکیده
This paper presents an empirical task-based user evaluation, which was carried out for the purpose of assessing the subjective QoS of a mobile multimedia web service in a real multi-access network environment comprising of WLAN and GPRS networks and automatic mobility management with Mobile IP. Subjective quality ratings were collected from 20 test users to obtain a distribution representing the service quality experienced by the subjects. The obtained results show that even though the service usability in GPRS domain was barely satisfactory, this type of automatic utilization of multiple access networks with some enhancements can be considered as a potential access method for mobile services.

New generation of wireless networks, LTE and WiMAX, supports many services which consume a lot of resources (such as VOIP, Video Conference, Digital Video, Multimedia streams and online Multi-player Games). Supporting multi-media services in wireless communication systems provide new resource allocation challenges. Because of high loads in downlink, efficient resource allocation is vital in dow...
متن کاملEnd User Service Quality in Multi-access Networks
The concept of multi-access is a widely accepted scenario for the future mobile Internet. Multi-access enables a mobile user whose terminal supports more than one access network technology to maintain an optimal connection to the used services by dynamically routing traffic via the best available access at any location. Mobility in a multi-access network however presents the user and the applic...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

In this paper we present a novel QoS framework on the network layer for 5G terminals with vertical multihoming and multi-streaming capabilities by using radio networks aggregation. The proposed framework is leading to high performance utility networks with QoS provisioning for real-time multimedia services by achieving low packet delays, stochastic queuing network stability and highest mobile b...

Since, most of the organizations present their services electronically, the number of functionally-equivalent web services is increasing as well as the number of users that employ those web services. Consequently, plenty of information is generated by the users and the web services that lead to the users be in trouble in finding their appropriate web services. Therefore, it is required to provi...
