S2: Smart City – Hardware and Systems

		1. Improving trilateration for indoors localization using BLE beacons
		Aitor De Blas and Diego López-de-Ipiña (University of Deusto, Spain)
		While the Global Positioning System (GPS) tends to be not useful anymore,in terms of precise localization once one gets into a building, Low,Energy beacons might come in handy instead. Navigating free of signal,reception problems throughout a building when one has never visited that,place before is a challenge tackled with indoors localization. Using,Bluetooth Low Energy (BLE) beacons (either iBeacon or Eddystone formats),is the medium to accomplish that. Indeed, different purpose oriented,applications can be designed, developed and shaped towards the needs of,any person in the context of a certain building. This work presents a,series of post-processing filters to enhance the outcome of the,estimated position applying trilateration as the main and,straightforward technique to locate someone within a building. A later,evaluation tries to give enough evidence around the feasibility of this,indoor localization technique. A mobile app should be everything a user,would need to have within a building in order to navigate inside.
		2. Real Time System for Acquiring and Logging the Plan Position Using NI MyRIO Controller
		Raluca Rob, Stela Rusu-Anghel and Caius Panoiu (Politehnica University of Timisoara, Romania)
		Present paper proposes a system for establishing in real time the,current geographical positioning with high accuracy. The system is,composed by a NI MyRIO controller equipped with FPGA and Real time,technologies which communicates with a laptop as the host computer and a,GPS module. Using an appropriate soft application accomplished in,LabVIEW, the GPS data is processed and having Internet connection, the,application may also set the current positioning on Google Earth maps.,This is possible by designing shared variables which provide,communication in real time between files. The update rate is set to,10Hz. The LabVIEW application can save the GPS data into documents in,order the information to be post-processed.
		3. A DDS-PLL beam steering polar transmitter for narrowband IoT communications
		Giulio D’Amato, Gianfranco Avitabile and Giuseppe Coviello (Politecnico di Bari, Italy); Claudio Talarico (Gonzaga University, USA)
		This work presents the design and implementation of a low-complexity,beam steering polar transceiver based on a revised DDS-PLL phase shifter,architecture. The proposed modulator-less topology targets narrowband,communications for enhanced Internet-of-Things systems, and has been,prototyped using an FPGA evaluation board and a custom PCB with four,PLLs centered at 2.453-GHz. Measured system performance are discussed,for an experimental data rate of 32-Kbps achieved through the,implementation of a 16-PSK modulation. Being a frequency independent,architecture, the proposed solution represents a very effective choice,in multi-band devices and it has the potential for being integrated as,an RF System-on-Chip.
		4. Performance Evaluation of NovaGenesis Information-Centric Network
		Antonio M. Alberti, Élcio do Rosário, Giovani Cassiano, Jorge Carneiro, Victor Hugo Domingues D’Avila and José dos Santos (National Institute of Telecommunications (INATEL), Brazil)
		Content distribution is one of the main applications in current Internet,and have emerged to allow access to content by their names,,independently of location. Network caching, content replication,,name-based routing/forwarding and efficient content distribution are,main requirements in contemporary architectures, including 5G, Internet,of things and future Internet. In this paper, we address these,challenges in the context of a novel architecture called NovaGenesis,(NG). Our approach integrates information-centric networking (ICN),,service-oriented architecture, “semantics rich” orchestration,(coordination) and identifier/locator splitting to provide efficient and,secure content distribution. To proof-the-concepts behind our,integrated solution, we also designed and implemented a distributed,,policy-driven, content management application. We report promising,experimental results, which put NovaGenesis as an alternative to current,ICN architectures.
		5. eMoorings: Distributed Low Power Wide Area System to Control Moorings
		Matea Bešlić, Mario Čagalj, Toni Perković, Ivo Stančić and Goran Pavlov (University of Split, Croatia)
		Low Power Wide Area (LPWA) networks present a new communication paradigm,in wireless sensor networks. Their ability to convey information over,larger geographical areas, while still enabling low-power consumption,and longer lifetime, gives them a special place in realization of,Internet of Things (IoT) systems and applications. Compared to,traditional cellular networks and other short range technologies (WiFi,,Bluetooth or ZigBee), LPWA systems rely on reduced complexity and cost,of end sensor devices, and higher complexity of centralized systems.,In this paper we present eMoorings, a system of distributed sensors to,control moorings in marinas. The delay tolerant feature of sensor,devices connected to rope of mooring allows us to implement low cost and,low power consumption sensor device active only a small fraction of,time while being inactive most of the time. The simultaneous and robust,monitoring of a large number of moorings – more than 100 is based on the,centralized system that handles and coordinates communication,activities of all sensor devices in the network.,We implemented the proposed system with off-the-shelf components such as,Arduino and Raspberry Pi and tested the reliability of the system in,laboratory environment.
