Ad hoc innovation: distributed decision making in ad hoc networks
(IEEE, 2006)Mobile ad hoc networks by their nature are highly adaptive systems that can come into existence on an as needed basis. They can grow, reduce in size, fragment, and dismantle as desired. The dynamic and very flexible nature ... -
Analysing the security threats against network convergence architectures
(IEEE Computer Society Press, 2007)Current research trends in networks and telecommunications suggest that future architectures will aim for the convergence not only of fixed and mobile infrastructures, but also of different network layer technologies. ... -
Architectures for person to person communications in disaggregated networks
(IEEE, 2006)Current telecommunications systems allocate identifiers to devices, and end-points. While this has worked well thus far, we believe that as more devices are used to access these systems, people have a tendency to be mobile ... -
Cognitive radio: value creation and value migration
(2006)This paper develops the concept of a telecommunications value-chain and explores the many ways in which the valuechain can be altered by reconfigurable software-defined radios, cognitive radios and cognitive networks. ... -
A cost analysis of optical IP switching in new generation optical networks
(IEEE, 2006)In this paper we propose a simple model that analyzes the cost saving achieved by optical IP switching (OIS), a novel optical architecture, compared to a conventional IP-over-WDM network, where the IP router connects ... -
Cost study of dynamically transparent networks
(Optical Society of America, 2008)The network equipment cost benefit of dynamic wavelength routing is compared with point-to-point IP networks and static wavelength routing in a simple ring topology with variable network traffic loading. -
Dynamic optical path allocation in multi-layer traffic engineering
(2007)Hybrid electro-optical architectures have been recently proposed as cost-effective solution to challenge nearfuture traffic demands. We believe that IP routing technology can be closely integrated with optical circuit ... -
EuroBridge methodology for telecommunications service specification
(IEEE, 1993)In designing and specifying a system that will be used to provide telecommunications services to a user population, it is important to identify all major actors involved, and their individual concerns at an early ... -
Feasibility of flow-based optical provisioning in GEANT
(Optical Society of America, 2007)We present a novel network architecture that establishes dynamic optical paths by analyzing local network traffic. We demonstrate its feasibility and effectiveness through a network analysis using real traces collected ... -
Flexible real-time payment methods for mobile communications
(IEEE, 2000)The method of billing users for mobile telephony is based on systems developed over time for fixed networks. We survey the technology involved, and argue that these systems will become increasingly inadequate for large ... -
Instant messaging and presence management in mobile ad-hoc networks
(IEEE, 2004)The combination of real-time message delivery and presence awareness has to lead the rapid rise in popularity of Instant Messaging (IM) in recent years. The extension of IM to mobile ad-hoc networks certainly offers ... -
Overlay networks : a scalable alternative for P2P
(IEEE, 2003)Overlay networks create a structured virtual topology above the basic transport protocol level that facilitates deterministic search and guarantees convergence. Overlay networks are evolving into a critical component for ... -
A policy-driven trading framework for market-based spectrum assignment
(IEEE, 2007)We present a policy-driven trading framework for market-based spectrum assignment. Our work allows spectrum consumers to get exclusive access rights through payment of a fee, for a given period of time, and for a given ... -
Secure pay-per-view testbed
(IEEE, 1995)Trials of video on demand and pay-per-view systems are underway in many countries, and as a result, many cable and telecommunications companies are having to upgrade or replace their distribution networks. Video streams ... -
Secure routing for mobile ad-hoc networks
(IEEE, 2005)In this article we present a survey of secure ad hoc routing protocols for mobile wireless networks. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing ... -
Security considerations in a network management environment
(IEEE, 1994)Considers the security aspects of communication between two management processes operating in different management domains; identifies two major risks: the security of information exchanged during the management association, ... -
Shared RSA key generation in an mobile ad hoc network
(IEEE, 2003)The use of a threshold certificate authority to provide cryptographic key management in mobile ad hoc networks has been suggested in the literature. We have designed and implemented such a key management service for our ... -
Signal space based adaptive modulation for software radio
(IEEE, 2002)This paper describes an automatic modulation scheme recognition technique. The technique is designed for a real-time software radio using general purpose processors and is based on modified pattern recognition and ...
