The University of Piraeus, through the work Telecommunication Networks and Services (TNS) Laboratory of the Department of Digital Systems, is establishing a XiFi node, which has the working title iWave (Internet of Things, Wireless Access and Virtualization Technologies for an Advanced Future Internet Experimentation Node).
TNS XiFi Node Overview
The TNS XiFi Node comprises an infrastructure with several hardware devices and software components, supporting the execution of a great variety of experimentations, particularly in the areas of Internet of things (IoT) and Wireless Sensor Networks (WSN), as well as advanced wireless access covering open WiFi/LTE access points and Software Defined Radios (SDR). The TNS XiFi Node will mainly focus on the research and experimentation in new areas with innovative technologies for the FI-PPP and FI developers and users.
XiFi / FIWARE-enabled Architecture
The TNS XiFi Node architecture (Figure 1) is comprised of three different segments: (a) the Core Network and Servers (CNS), (b) 4G/B4G – Wireless Broadband Network (WBN) and (c) the Wireless Sensor/Actuator Network (WSN/WSAN). The CNS segment includes the computing, storage and networking devices (resources) as well as the backbone, teeing together all the network elements. The 4G/B4G WBN allows for advanced wireless experimentations based on a plethora of Radio Access Technologies (RATs) including among others cellular UMTS/HSDPA/LTE as well as the IEEE 802.11 suite of standards. The WSN/WSAN (i.e. the IoT infrastructure) includes a wide range of heterogeneous sensing devices that allow for monitoring of both the indoor and outdoor environmental conditions. Further to that, the infrastructure has been designed, developed and configured in a way so as to enable its future extension by adding new sensing devices/integrated platforms from the field of Intelligent Transportation Systems (ITS), such as traffic management sensors.
By introducing the XiFi/FIWARE capabilities, such as FIWARE Ops and the Generic Enables (GEs), into the TNS Node architecture, the node is enhanced in terms of devices interoperability, heterogeneous data aggregation and the provision of powerful and reliable IT services to the private and public sector. In particular, including the Backend Device Management (BDM) GE, combined with Specific Enablers (SE) being developed and/or customized by TNS Lab, facilitate the interoperability and easy integration of heterogeneous components in the WSN/WSAN. Moreover, the Orion Context Broker (CB) GE local instances that are hosted in TNS data center, allow the storing and the aggregation of data from the WSN/WSAN. The TNS XiFi Node deployment, federation and management is achieved by exploiting the FIWARE Ops, supported by the XiFi Infrastructure Toolbox (ITBox). Finally, the public access to the node is achieved by exploiting the BigData Analysis – Cosmos GE Global Instance in FIWARE Cloud, which offers public access to Orion CB GE global instance, while the users who are authenticated in FIWARE Cloud, use the FIWARE VMs in order to access the TNS XiFi Node (FI-Lab Instance).
