On QOS Mapping in Multimedia Networks
نویسندگان
چکیده
A framework for studying QOS mapping between various levels in the information transport protocol stack and a platform for evaluating the mapping rules by performing concurrent network and application level measurements of QOS are presented. An empirical loss mapping rule between the application (frame) level and network (cell) level is given. The rule was tested using two 10 minutes motion JPEG video clips and a 30 minutes MPEG-2 VBR video clip under 55 different network load conditions and gives results within a 3% error margin.

A Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...

This paper presents the design and implementation of a QoS parameter mapping emulator. The emulator is used in selecting the appropriate network parameters in such a way as to provide optimum quality for transmitted multimedia between EDGE and UMTS networks.
متن کاملA cross-layer design for efficient video transmission over wireless networks: statistical QoS optimisation
Studies on the cross-layer design for efficient multimedia delivery with QoS assurance over wireless networks utilize the differentiated service architecture to convey multimedia data. The common approach is the partitioning of multimedia data into smaller units, and then maps these units to different classes for prioritized transmission. The partitioned video units are prioritized based on its...

The third-generation partnership project 3GPP and 3GPP2 have standardized the IP multimedia subsystem (IMS) to provide ubiquitous and access network-independent IP-based services for next-generation networks via merging cellular networks and the Internet. The IP Multimedia Subsystem (IMS) seems to be the technology that will prevail in Next Generation Networks (NGNs). The users wish to communic...
متن کاملDynamic User-Oriented QoS Specification and Mapping for Multimedia Differentiation Services
This paper proposes the Dynamic User-Oriented QoS Framework (DUQF), which provides the effective adaptation control schemes for dynamic QoS specification and mapping based on the combination of DiffServ and IntServ network architecture. A DUQF network consists of a DiffServ WAN and lots of attached IntServ LANs that connect to each other via a RSVP-aware router and a differentiation edge router...
