Enabling Internet-of-Things services in the MobilityFirst Future Internet Architecture

In the emerging paradigm of pervasive computing, applications change their behaviors in response to their environmental context, which is provided by the smart objects in the Internet of Things (IoT). Due to the inherent heterogeneity of physical world objects, realizing the IoT requires service layers to fill the gap between the low level interfaces of networked objects and the applications which use them. In this paper, we show that the MobilityFirst Future Internet Architecture is an ideal platform for realizing pervasive computing in an IoT framework. In particular, MobilityFirsts identity based routing, overloaded identities, content caching and in-network compute plane are excellent building blocks for IoT applications. We then present a detailed example of a location based service built using MobilityFirst.

Delivering Internet-of-Things services in MobilityFirst Future Internet Architecture

In the emerging paradigm of pervasive computing, applications change their behaviors in response to their environmental context, which is provided by the smart objects in the Internet of Things (IoT). IoT envisions building a convergent platform to share dynamic data from smart objects and middleware services that process the data. In this paper, we show that the MobilityFirst Future Internet Architecture is an ideal platform for realizing pervasive computing in an IoT framework. In particular, MobilityFirsts identity based routing, overloaded identity resolution, content caching and in-network compute plane are excellent building blocks for IoT service distribution. We then present a detailed example of a location context-aware service built as a dynamic content service, and discuss innetwork distribution of this IoT service via MobilityFirst future Internet, whereas now only possible via overlay content distribution network (CDN).

Publish/subscribe on top of DHT using RETE algorithm

This paper discusses the construction of a Global Semantic Graph (GSG) [1] to support future information- and collaboration-centric applications and services.TheGSGis a publish/subscribe (pub/sub) based architecture that supports publication of tuples and subscriptions with standing graph queries. We believe that an implementation of an efficient pattern matching algorithm such as Rete [2] on top of a distributed environment might serve as a possible substrate for GSGs pub/sub facility. Rete operates on loosely coupled alpha, beta and join nodes and therefore has been chosen by us for implementation in a distributed setting. In this paper, we propose a way to perform Retes pattern matching over a DHT-based Structured P2P network to provide a scalable contentbased publish/subscribe service.

Global semantic graph as an alternative information and collaboration infrastructure

We propose the development of a Global Semantic Graph (GSG) as the foundation for future information and collaboration-centric applications and services. It would provide a single abstraction for storing, processing and communicating information based on globally interlinked semantic resources. The GSG adopts approaches and methods from the Semantic Web and thus facilitates a better information sharing abstraction.

Design for change: Information-centric architecture to support agile disaster response

This paper presents a case for the adoption of an information-centric architecture for a global disaster management system. Drawing from a case study of the 2010/2011 Queensland floods, we describe the challenges in providing every participant with relevant and actionable information. We use various examples to argue for a more flexible information dissemination framework which is designed from the ground up to minimise the effort needed to fix the unexpected and unavoidable information acquisition, quality, and dissemination challenges posed by any real disaster.

NICTA ATP lab: Eveleigh, Sydney, Australia

N ICTA (National ICT Austra-lia) is Australias Information and Communications Technology Research Centre of Excellence. NICTA develops technologies that generate economic, social, and environmental benefits for Australia. NICTA collaborates with industry on joint projects, creates new companies, and provides new talent to the ICT sector through a NICTA-enhanced Ph.D. program. With six laboratories around Aus-tralia and more than 700 people, NICTA is the largest organization in Australia dedicated to ICT research. NICTAs research focuses on the following areas: computer vision, control and signal processing, machine learning, networks, optimization, and software systems. I am a Ph.D. student in the School of Engineering and Information Technologies at the University of Syd-ney. As well as a graduate researcher at NICTA Australian Technology Park (ATP) Laboratory in the Networks Research Group, which aims to improve overall user experience in accessing information and services by looking into ways to leverage the existing and researching into new infrastructure. NICTA provides many resources and other great opportunities that enhance research. My research focuses on large-scale networking systems. In particular we are developing Moana, a new Internet service abstraction. The Internet was originally designed for efficient data communication between end devices, but this is an increasingly ill-fitting model for todays information cen-tric services. We therefore argue for a network service model that instead focuses on interlinking information providers and consumers through a global information network. Moana is a global information storage and dissemination network, which simplifies developing and deploying of information rich applications. Moana loosely couples applications through a global information space that uses a Pub/ Sub communication model to communicate by publishing and subscribing to information. We are aiming to close the gap between the information model of an application and the supporting network service. We hope Moana will inspire the development of new types of information-centric applications by simplification of storage and dissemination and retrieval of information on an Internet-scale. NICTA has strong collaborations with leading research institutions around the world; we frequently get visiting researchers and intern students from all over Australia and the globe. This is a great way to extend our professional network and collaborate with other research institutions. In addition, students are offered a range of short courses for free. These courses are lectured by some of the best LABZ NICTA is all about growth, collectively as a lab and individually as a researcher.

Into the Moana 1 — Hypergraph-based network layer indirection

In this paper, we introduce the Moana network infrastructure. It draws on well-adopted practices from the database and software engineering communities to provide a robust and expressive information-sharing service using hypergraph-based network indirection. Our proposal is twofold. First, we argue for the need for additional layers of indirection used in modern information systems to bring the network layer abstraction closer to the developers world, allowing for expressiveness and flexibility in the creation of future services. Second, we present a modular and extensible design of the network fabric to support incremental architectural evolution and innovation, as well as its initial evaluation.

Towards a Kademlia DHT-based n-tuple store

In this paper, we describe our work towards a novel n-tuple store based on the Kademlia DHT that supports multidimensional storage and multi_get(pattern) query operation. We present our algorithm behind multi_get along with preliminary results on its performance.
