Multimedia service composition provides a flexible way of building customized multimedia content production and delivery by composing distributed multimedia-oriented services dynamically to provide new functionalities. Previous researches have addressed various aspects of multimedia service composition such as composability, QoS-awareness, and load balancing. Most of them however have assumed that...
Wireless mesh networks (WMNs) are promising last-mile access network with large coverage and low deployment and operational cost. As the realization of WMNs becomes attainable, business opportunities have focused a number of applications such as multimedia streaming. However, in the case of multiple clients streaming, intrinsic nature of wireless medium sharing property results severe streaming bandwidth...
As the demand for real-time IP media transport over multi-point delivery environments increases, it is essential to monitor the time-varying status of both network metrics (i.e., delay, jitter, and loss) and system metrics (i.e., CPU and memory utilization). In this paper, we propose and implement a new monitoring system for the high-quality real-time media delivery over multicast-enabled network...
In this paper, we propose an adaptive event synchronization control for distributed virtual environment (DVE) systems connected over dynamically time-varying networks. Existing adaptive synchronization approaches still have two challenges: disturbance by network traffic load fluctuation and event skipping by contracting the playout delay. Thus, by adopting so-called adaptive event synchronization...
