Most of things would be connected into internet and it will be evolved into web of objects(WoO) which can share the information each of the thing-in-itself with the internet of things(IoT) service environment. The web of object in IoT objectifies and virtualizes things and it generates and provides new services with mashup of objectified things with context information. The thing in the web of object...
The evolution of telecommunications technology from circuit to packet switching, in which the Internet is the great paradigm, offers nowadays more flexibility in services and higher efficiency in the transport infrastructure that was not experienced before. As consequence, several new services have emerged. Among them, Voice over IP (VoIP) is, indubitably, one of the most popular, mainly because it...
The essence of the voice resource DoS attacks, which are unusual in telecom networks, is the malicious occupation of called party link resource. Softswitch technology achieves the inter-communication between Internet and telecom networks. Voice over Internet Protocol (VoIP) describes the transmission of voice using packet switched networks. And H.323 is one of the standards used in VoIP. The H.323...

Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
