© 2015 IEEE.Limited scalability, reliability, and security of todays utility communication infrastructures are main obstacles to the deployment of smart grid applications. The C-DAX project aims at providing and investigating a communication middleware for smart grids to address these problems, applying the information-centric networking and publish/subscribe paradigm. We briefly describe the C-DAX architecture, and extend it with a flexible resilience concept, based on resilient data forwarding and data redundancy. Different levels of resilience support are defined, and their underlying mechanisms are described. Experiments show fast and reliable performance of the resilience mechanism.

The demand for resource-hungry applications whilst on the move is growing, and is being fuelled in particular by the increasing availability of high-quality multimedia services. To this end, micro-mobility protocols play an important role in providing seamless data delivery to terminals as they roam across different networks. However, such protocols typically lead to bottleneck congestion occurring within the access network. Within moving networks, in which a potentially vast number of terminals are present, the bottleneck congestion problem is significantly magnified, and can lead to increased call dropping probability and/or quality-of-service degradation. This paper therefore presents a novel mechanism, designed to ensure that the continuity of all sessions of a moving network is seamlessly preserved as it performs handovers to and within micro-mobility- enabled access networks
Dev Pragad A, Kamel G, Pangalos P, Aghvami AH (2008) A Combined Mobility and QoS Framework for Delivering Ubiquitous Services, IEEE
From a network perspective, the major challenge in providing seamless connectivity whilst maintaining the required level of QoS to users results from the negative interactions that occur between mobility and QoS. These interactions, particularly those of mobility and QoS, have been the subject of much research. In this paper, we discuss the various approaches that have already been taken to combine QoS and mobility mechanisms, and present a new framework to combine such mechanisms with the aim of reducing the negative interactions that might arise between them. We propose the concept of enhanced nodes which is a special IP router with an extra sub-layer of mobility, QoS and security features. Our framework is illustrated with an example of a QoS-based mobility selection mechanism.

Information-centric networking (ICN) is an emerging
networking paradigm that places content identifiers rather
than host identifiers at the core of the mechanisms and protocols
used to deliver content to end-users. Such a paradigm allows
routers enhanced with content-awareness to play a direct role
in the routing and resolution of content requests from users,
without any knowledge of the specific locations of hosted content.
However, to facilitate good network traffic engineering
and satisfactory user QoS, content routers need to exchange
advanced network knowledge to assist them with their resolution
decisions. In order to maintain the location-independency tenet
of ICNs, such knowledge (known as context information) needs
to be independent of the locations of servers. To this end, we
propose CAINE ? Context-Aware Information-centric Network
Ecosystem ? which enables context-based operations to be
intrinsically supported by the underlying ICN routing and resolution
functions. Our approach has been designed to maintain the
location-independence philosophy of ICNs by associating context
information directly to content rather than to the physical entities
such as servers and network elements in the content ecosystem,
while ensuring scalability. Through simulation, we show that
based on such location-independent context information, CAINE
is able to facilitate traffic engineering in the network, while not
posing a significant control signalling burden on the network

The Internet, the de facto platform for large-scale
content distribution, suffers from two issues that limit its manageability,
efficiency and evolution: (1) The IP-based Internet
is host-centric and agnostic to the content being delivered and
(2) the tight coupling of the control and data planes restrict its
manageability, and subsequently the possibility to create dynamic
alternative paths for efficient content delivery. Here we present
the CURLING system that leverages the emerging Information-
Centric Networking paradigm for enabling cost-efficient Internetscale
content delivery by exploiting multicasting and in-network
caching. Following the software-defined networking concept that
decouples the control and data planes, CURLING adopts an
inter-domain hop-by-hop content resolution mechanism that
allows network operators to dynamically enforce/change their
network policies in locating content sources and optimizing
content delivery paths. Content publishers and consumers may
also control content access according to their preferences. Based
on both analytical modelling and simulations using real domainlevel
Internet subtopologies, we demonstrate how CURLING
supports efficient Internet-scale content delivery without the
necessity for radical changes to the current Internet.
