3. A novel JXTA-based architecture for implementing heterogenous Networks of Things

Author

Battaglia, Filippo and Bello, Lucia Lo

Subjects
Computer Science - Networking and Internet Architecture
Abstract

This paper presents EmbJXTAChord, a novel peer-to-peer (P2P) architecture that integrates the good features of different sources, such as JXTA, EXI, CoAP, combining and augmenting them to provide a framework that is specifically devised for developing IoT applications over heterogeneous networks. EmbJXTAChord provides for several interesting properties, such as, distributed and fault-tolerant resource discovery, transparent routing over subnetworks, application protocol independence from the transport protocol in narrowband WSN, thus eliminating the need for using dedicated software or configuring custom gateways to achieve these functionalities. Moreover, EmbJXTAChord offers native support not only for TCP/HTTP, but also for Bluetooth RFCOMM and 6LoWPAN, thus opening to a broad range of IoT devices in supernetworks composed of networks using different interconnection technologies, not necessarily IP-based. In addition, EmbJXTAChord offers security over heterogeneous networks providing support for secure peergroups (even nested) and for group encryption, thus allowing for unicast and multicast communication between groups of objects sharing the same resources. Finally, EmbJXTAChord provides jxCOAP-E, a new CoAP implementation that leverages on the transport mechanisms for heterogeneous networks offered by EmbJXTAChord. jxCOAP-E enables to realize a RESTful service architecture for peer-to-peer narrowband or broadband networks composed of devices connected via Ethernet, Wi-Fi, Bluetooth, BLE or IEEE 802.15.4. Differently from CoAP, jxCOAP-E provides a distributed and fault-tolerant service discovery mechanism and support for secure multicast communications. The paper presents EmbJXTAChord, discusses all the relevant design challenges and presents a comparative experimental performance assessment with state-of-the-art solutions on commercial-off-the-shelf devices., Comment: 54 pages, 16 figures

21. Design and implementation of an educational testbed for experiencing with industrial communication networks

Author

Bello, Lucia Lo, Mirabella, Orazio, and Raucea, Antonino

Subjects

Abstract

This paper presents the design and implementation of an educational testbed developed for a course on industrial communication networks at the Engineering Faculty, University of Catania. The aim is to realize a platform capable of emulating various network configurations, thus enabling students to find out by themselves through practical experiments how different design choices, parameter settings, network configurations, and algorithms impact on the overall network performance. The testbed comprises a number of basic components (hosts, routers, and access points) implemented on nodes equipped with operating systems and open source software, which together make up a modular system. Each router can be loaded with data flows and monitored over preestablished time windows so as to evaluate its performance in a wide range of operating conditions. The wireless part makes it possible to configure environments with different levels of noise and bandwidth utilization so as to emulate a broad spectrum of real operating environments. The testbed can be used via remote access through a web interface that not only allows the operating conditions to be configured but also permits real-time monitoring. Students can configure the testbed on the basis of the network they are studying and can measure its performance for evaluation purposes. Index Terms--Communication engineering education, computer networks, measurement, scheduling, wireless LAN.

22. Relay Node Selection in Bluetooth Mesh Networks

Author

Reno, Marco, Rondón, Raúl, Bello, Lucia Lo, Patti, Gaetano, Mahmood, Aamir, Lombardo, Alfio, Gidlund, Mikael, Reno, Marco, Rondón, Raúl, Bello, Lucia Lo, Patti, Gaetano, Mahmood, Aamir, Lombardo, Alfio, and Gidlund, Mikael

Abstract

Bluetooth Mesh (BM) is a new communication protocol for the Internet of Things that is used to establish many-to-many device communication. BM allows for easy creation of large connection-less mesh networks using a controlled-flooding propagation mechanism, in which relay nodes broadcast the received messages to all neighbors until the message reaches its destination. This model, however, makes BM networks susceptible to broadcast-storm effects, which can hinder the scalability of the protocol. Opportune relay node selection is therefore of critical importance to control network traffic and improve network performance. This paper focuses on the choice of relay selection algorithms suitable for BM networks. In particular, different centralized, decentralized, and localized algorithms based on Connected Dominating Set (CDS) are evaluated and compared.

48. Guest Editorial Special Section on Communications in Automation?Innovation Drivers and New Trends.

Author

Bello, Lucia Lo, Behnam, Moris, Pedreiras, Paulo, and Sauter, Thilo

Abstract

The papers in this special section focus on telecommunication services in automation applicaitons. The evolution of automation systems has always been the result of continuous improvements to state-of-the-art systems, occasionally punctuated with significant paradigm and architectural changes that acted as innovation drivers. This happened with the industrial revolutions, which had in their origin the appearance of disruptive technologies, such as the steam engine and machine tools (first industrial revolution); electrification, mass production, and assembly lines (second industrial revolution); use of microprocessors and software (third industrial revolution).
