Topology is a fundamental part of a network that governs connectivity between nodes, the amount of data flow and the efficiency of data flow between nodes. In traditional networks, due to physical limitations, topology remains static for the course of the network operation. Ubiquitous data networks (UDNs), alternatively , are more adaptive and can be(More)
This paper focuses on the problem of how to provide home network users a way to access the TINA services using a CORBA-enabled Residential Gateway. It proposes a standardised service architecture for the Next Generation Network. Additionally intelligent control and management schemes at the RGW are addressed. Issues such as billing, bandwidth allocation and(More)
Modern living is more and more dependent on the intricate web of critical infrastructure systems. The failure or damage of such systems can cause huge disruptions. Traditional design of this web of critical infrastructure systems was based on the principles of functionality and reliability. However, it is increasingly being realized that such design(More)
In MANET there are many attacks, the black hole attack is one of the well-known security threats in mobile ad-hoc networks. The attacker node utilizes the illegal action to carry out their malicious behaviors because the route discovery process is necessary and inevitable. Many researchers have conducted different detection techniques to propose different(More)
This document gives a framework for a research project that addresses the delivery of streamed services to a Residential Gateway (RGW). The Telecommunications Information Networking Architecture (TINA) is followed to allow for an NGN service provision, and CORBA is used for the coding. The design incorporates prior techniques and services that have been(More)
