Multimedia streaming applications have disruptively occupied bandwidth in wire line Internet, yet today's fledging mobile media streaming still poses many challenges in efficient content distribution due to the form of mobile devices. At the same time, cloud computing is gaining power as a promising technology to transform IT industry and many eminent enterprises are developing their own cloud infrastructures...
The proliferation of networked appliances or dedicated function consumer devices with embedded processors and network connection capabilities is driving the virtual device concept, whereby such appliances can be controlled, monitored, managed, and extended beyond what they were initially designed to do. The dynamic and ad hoc nature of the discovery and composition of such devices and the services...
Malware attacks constitute a serious security risk that threatens to slow down the large scale proliferation of wireless applications. As a first step towards thwarting this security threat, we seek to quantify the maximum damage inflicted on the system owing to such outbreaks and identify the most vicious attacks. We represent the propagation of malware in a battery-constrained mobile wireless network...
In this paper, we address the problem of collaborative video caching in mobile ad-hoc networks. We consider network portraying static video server with wired interface to gateway node that is equipped with wireless interfaces, other nodes are requiring access to the video streams that is stored at video server. In order to reduce the average access latency as well as enhance the video accessibility,...
Delivering protected seamless content services over heterogeneous networks should be solidly sustained on top of architectures that can offer support for guaranteed quality delivery according to network or consumer requirements. The delivery of personalized, scalable, seamless, and trusted multimedia content delivery, while adequately protecting the content, is a key factor to provide seamless content...
The media independent handover (MIH) architecture is designed to facilitate the signaling and enable seamless handovers in heterogeneous networks. In this paper, we propose a solution using the stream control transmission protocol (SCTP) to efficiently carry MIH messages. The solution uses SCTPpsilas multihoming and multistreaming capabilities along with cross-layer information available through the...
This contribution addresses the case when live packet-switched video is used to enrich circuit-switched speech calls in mobile telephony. Circuit-switched and packet-switched transmissions generally operate on completely different transmission paths resulting in different QoS in terms of delay and loss rates. In this case, video and audio data recorded at the same time are not multiplexed together...
