 To guarantee quality of service (QoS), the requirements for video transmission such as delay and cell loss rate (CLR) are very stringent. These constraints are difficult to meet if high network utilization is desired. Dynamic bandwidth allocation is thus needed. Video traffic prediction can play an important role in dynamic bandwidth allocation and traffic management in high-speed networks. I...

A coherent computer-based multimedia presentation requires the use of real-time scheduling theory applied to system resources including storage devices, the bus, and network. In this paper we present a scheduling technique which is essentially static in nature during periods of network quiescence, but becomes dynamic in response to detection of network load changes or user interaction. This mec...

Temporal relationships are a characteristic feature of multimedia objects. Continuous media objects such as video and audio have strict synchronous timing requirements. Composite objects can have arbitrary timing relationships. These relationships might be specified to achieve some particular visual effect of sequence. Several different schemes have been proposed for modeling time-based media. ...

Vehicular Ad-hoc Networks (VANETs) have recently attracted a lot of attention, as a tool to disseminate information among vehicles with the dual purpose of increasing road safety and comfort in driving. The majority of messages exchanged by vehicles are characterized by a finite lifetime period, after which, their level of usefulness is greatly reduced. Thus, an important problem in VANETs is t...

Many manufacturing and distribution firms guarantee to meet a standard delivery time promise and pay significant compensation to customers when deliveries are late. If the firm promises its customers a delivery time that is too short, it will frequently not make the promise, have to pay significant compensation, and possibly lose market share over time. If the delivery time guarantee is too lon...

To understand sensory processing in neuronal populations, it is necessary to deliver stimuli to the sensory organs of animals and record evoked population activity downstream. However, the pathways from sensory input to synaptic currents in cells that are several synapses removed from sensory organs are complex. Intrinsic noise and uncontrolled modulatory input from other brain regions can inte...

In live streaming systems (IPTV, life-stream services, etc.), an attractive service consists in allowing users to access past portions of the stream. This is called a time-shifted streaming system. In our vision, a centralized time-shifted streaming system face scalability and ethical issues, therefore, we address the problem of designing a peer-to-peer system where peers store and deliver past...
