We present a novel and complete tool-set for evaluating the delivery quality of MPEG video
transmissions in simulations of a network environment. This tool-set is based on the EvalVid …

Jobs on most high-performance computing (HPC) systems share the network with other
concurrently executing jobs. This sharing creates contention that can severely degrade …

In this letter, we develop a general delivery system for streaming using various coding
standards over DiffServ (DS) networks. In the delivery system, the coder at the application …

Mobile ad hoc networks without centralized infrastructure change their topology rapidly
because of node mobility, making multimedia applications difficult to run across wireless …

Presenting an advanced simulation tool-set for video transmission performance evaluation
is the objective of this paper. This tool-set integrates NS-2 with Evalvid plus a new coding …

Recently, multimedia is a more and more important Internet service. For multimedia, Quality
of service (QoS) support is a crucial requirement. To meet these QoS requirements …

Cluster-based routes help data transmission by acting as backbone paths in wireless ad hoc
networks. Some mobile users form a cluster to obtain common multimedia services …

We propose an analytical model to derive from the packet loss rate an objective application-
level metric, the decodable frame rate (Q), thus allowing the evaluation of the packet loss …

Future high performance computing (HPC) systems will face unique problems, including
high power consumption and severe network contention. Both power and the network are …

IP-based radio access networks (RANs) are envisaged to be the next generation access
networks in UMTS. In order to provide a satisfactory level of quality of service (QoS) for real …
