Content Centric Networking (CCN) is a new paradigm in networking and a future Internet architecture. Performance evaluations show that conventional CCN forwarding strategies which use replication of Interests (standard) or the shortest path (best-face) do not perform well under high bandwidth requirements and loaded networks. We have designed and evaluated(More)
The Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol standard that was ratified recently by the Network-based Localized Mobility Management (NetLMM) working group of the Internet Engineering Task Force (IETF). PMIPv6 is a protocol that uses the same concepts as used in Mobile IPv6 (MIPv6), but modified to operate in the network(More)
Content Centric Networking (CCN) is an evolving paradigm in networking where communications are based on named content rather than the named hosts model of today's networks. Though CCN is capable of multi-path communications by design, no work has been done to characterise multi-path content transfers in CCN with an analytical model. In this work, we have(More)
Network virtualization is a concept where physical resources are used to create virtual resources that are combined to form virtual networks. As one of the key enablers of the future Internet, network virtualization solves a number of issues associated with today’s networks. Concepts of network virtualization that are not restricted to virtualization(More)
The Internet of Things (IoT) is expected to grow into billions of devices in the near future. Evaluating mechanisms such as networking architectures for communications in the IoT require the use of simulators due to the scale of the size of networks. Mobility is one of the key aspects that need to be evaluated when considering the different scenarios of the(More)
The Ad hoc On-Demand Distance Vector (AODV) routing protocol is designed for use in mobile ad-hoc networks. As of the writing of this article, there exist several implementations of the AODV protocol for a range of operating systems (e.g., Unix/Linux, Windows), different devices (e.g. Notebook computers, PDAs) each developed using different techniques and(More)
