Liberalising Deployment of Internet of Things Devices and Services in Large Scale Environments

There is an ongoing enormous expansion of Internet of Things devices andservices in everyday life, notably in novel large scale urban environments called Smart Cities. There, availability and uses of Internet of Things by end users and businesses is mainly palpable subject to prior knowledge of the relevant providers and use of dedicated applications that are associated with them. This current reality can be largely ascribed to the property of ‘‘verticality’’ of autonomous Internet of Things eco-systems in Smart Cities, where Internet of Things devices (e.g. sensor nodes) are connected over a communicationinfrastructure to service-cloud platforms that deliver and process data that isthen presented at the applications level. This paper explains possibilities for revolutionary changes needed towards liberalising deployment and visibility of IoT services and data associated with them. It advocates a conceptual approach termed ‘‘horizontal networking for Internet of Things’’ facilitating a more open and generic presence of Internet of Things through the proposed Internet of Things identification meta-data. The vision is built on needed novel practical features in the current communication setups. The features comprise combinations of the opportunistic and near-match search and discovery model, Internet of Things identification meta-data also reflecting the physical and network-based dimensions of devices’ locations, novel routing and data flow models emerging via Information-Centric Networking and changes required in the elements of the current telecommunicationinfrastructure and the Internet

A practical multi-plane routing-based traffic engineering scheme in evolutionary convergent all-IP access networks

With the expected surge in the global IP traffic, service providers would need to adapt accordingly to operate disruption and loss free networks supported with the developing IP infrastructure. With the disposal of the hierarchical network structure, radio access networks are moving towards a flat-IP architecture and novel topological set-ups in the backhaul. Hence, a routing paradigm that employs suitable Traffic Engineering (TE) techniques aligned with the developing nature of future access networks must be applied. In this paper, Multi-Plane Routing (MPR) that consolidates various aspects in all-IP infrastructure is remodelled in consistent with this development. We propose a MPR-based TE approach considering two different scenarios to reflect the evolution in the architectural design of access network structures under a realistic traffic scenario with a varying range of internal/external traffic. Accordingly, a practical performance evaluation testing the validity of the aforementioned scenarios is presented. Our simulation results demonstrate a better achieved performance under the flat-IP structure in addition to MPR-based methods' superiority over legacy OSPF/Invcap. Performance degradation is observed with the rise in the internal traffic distribution for the different scenarios studied. Moreover, a new optimization framework for the offline and online TE mechanisms of MPR have been proposed
