Advances in computing and networking technologies have revolutionised the way people communicate using interactive real-time applications such as instant messaging and audio and videoconferencing. This category of applications is nowadays readily available to users in terrestrial areas with high speed Internet connectivity. The aim of this work is to investigate the provision of IP-based network connectivity...
Video streaming is a very demanding application in its resources. We used a previously proposed architecture, to implement a solution that will use the GRID or a Cloud infrastructure to stream video. The goal was to create an application that will allocate resources dynamically and escalate in a manner corresponding to the demand. We developed and tested the application as a proof of concept and created...
This paper proposes a novel, adaptive medium access control mechanism for vehicular ad hoc networks. A simple, effective, and efficient nonlinear control law is built, based on fuzzy logic control principles, which can be easily adopted in different network environments (e.g. vehicle-to-vehicle (V2V) communication and vehicle-to-infrastructure (V2I) communication). We demonstrate, via simulative evaluation,...
A voice conversation is predominantly known as a synchronous, delay intolerant form of communication. To complement voice conversations, voice messaging is a form of asynchronous communication used when the called party is unavailable; a delay in message delivery is naturally expected and tolerated. To this extent, a Delay Tolerant Network can be utilized as the underlying data transport mechanism...
Vehicular networking is nowadays considered as one of the most important enabling technologies as it allows vehicles to communicate with each other (vehicle-to-vehicle (V2V) communication) and/or with roadside infrastructure (vehicle-to-infrastructure (V2I) communication). Vehicular ad hoc networks (VANETs) are ideal candidates for supporting various types of traffic applications, such as traffic...
Multimedia streaming is a well established application in today's Internet and broadcasts of live events are increasingly popular. It is often the case that network conditions change during a live broadcast and this can potentially lead to Quality of Service issues at the receiving clients. This paper proposes a multimedia streaming architecture that can adapt to changing network conditions. For scalability...
