This paper presents the information management of Voice over Digital Subscriber line (VoDSL) network architecture with implications for broadband access technology. A baseline test for the ability to support up to eight derived lines on the Integrated Access Device (IAD) for VoDSL by using voice quality transmission is introduced. This scheme carries out voice compression while countinously dow...

We study the outage probability performance of hybrid protocols in relay-assisted, non-orthogonal multiple access (NOMA)-based power line communication. In particular, we consider two networks with source, relay and destination nodes, namely, cooperative relaying NOMA (CR NOMA) single-stage (SS NOMA). derive closed-form expressions for probabilities three techniques, decode-and amplify-and-forw...

For a broadband wireless standard such as WiMax, security is important and must be addressed. This is to ensure wide acceptance both from the perspective of the end users and the service providers. In order to compete with existing broadband cable or DSL services, the WiMax network must offer comparable security. We discuss the WiMax security mechanisms for authentication, encryption, and avail...

While the amount of information available on line in the Internet or in the World Wide Web is increasingly growing many di erent systems have been developed to help the user to locate or gather information of interest In this paper we discuss the main approaches to the design of such systems focusing in particular on the methods used to represent the information available in the Web
