Keynote Speech

Combining IoT and Cyber world: Tools and methodologies to manage an urban environment
Prof. Antonio Puliafito, University of Messina, Italy

A smart city represents an improvement of today's cities both functionally and structurally, that strategically utilizes many smart factors, such as information and communications technology (ICT), to increase the city's sustainable growth and strengthen city functions, while ensuring citizens' quality of life and health. Cities can be viewed as a microcosm of "objects" with which citizens interact daily: street furniture, public buildings, transportation, monuments, public lighting and much more. Moreover, a continuous monitoring of a city's status occurs through sensors and processors applied within the real-world infrastructure. The Internet of Things (IoT) concept imagines all these objects being "smart", connected to the Internet, and able to communicate with each other and with the external environment, interacting and sharing data and information. Each object in the IoT can be both the collector and distributor of information regarding mobility, energy consumption, air pollution as well as potentially offering cultural and tourist information. As a consequence, cyber and real worlds are strongly linked in a smart city. New services can be deployed when needed and evaluation mechanisms will be set up to assess the health and success of a smart city. This talk will present some innovative developments in areas related to sensors and smart cities and introduce the crowdfunding #SmartME initiative.


Antonio Puliafito is a full professor of computer engineering at the University of Messina, Italy. His interests include parallel and distributed systems, networking, wireless and Cloud computing. He is acting as an expert in ICT for the European Commission since 1998. He is currently the President of the Centre on Information Technologies at University of Messina. He participated in several European projects such as Reservoir, Vision, CloudWave and Beacon. He currently is the scientific director of the SIGMA PON_01 project on the management and control of multi-risk systems. He recently constituted DHLabs srl, a startup developing solutions for the IoT. He is in charge of the #SmartME crowdfunding project.

Intelligent Demand Response towards Green and Reliable Smart Energy Networks
Dr. Yan Zhang, Simula Research Lab & University of Oslo

Smart energy networks is an emerging communication&networking paradigm that utilizes two-way communications architecture to closely monitor and efficiently support smart grid operations. This talk will mainly introduce our recent studies on intelligent demand response solutions for the control and optimization of smart energy networks. We will also present different approaches to model and solve the related problems, including game theoretical, adaptive dynamic programming, and price incentivized approaches.

Mobile Agents Rendezvous in the Presence of Faults

Dr. David Peleg (The Weizmann Institute of Science, Israel)

The talk will consider fault-tolerant solutions to the rendezvous problem, where a team of mobile agents, starting from different nodes of an unknown synchronous network, have to meet at the same node, in the presence of up to f Byzantine (faulty) agents. The problem will be examined assuming different levels of Byzantine behavior and different levels of knowledge available to the agents, with a focus on bounds on the minimum number of non-faulty agents that guarantees deterministic gathering.

David Peleg received the B.A. degree in 1980 from the Technion, Israel, the M.Sc. degree in 1982 from BarIlan University, Israel, and the Ph.D. degree in 1985 from the Weizmann Institute, Israel, all in computer science. He then spent a post-doctoral period at IBM Almaden and at Stanford University. In 1988 he joined the Department of Computer Science and Applied Mathematics at The Weizmann Institute of Science, where he is the incumbent of the Norman D. Cohen Professorial Chair of Computer Sciences.

Short tutorial

Utility-based Resource Allocation in Wireless Networks via Game Theory: Evolution from 3G to 5G

Dr. E.E. Tsiropoulou and Dr. S. Papavassiliou (NTUA, Greece)

The demand for high data rates and support of multiple services with various quality of service requirements has enjoyed exponential growth worldwide for decades, and looks to continue unabated into the foreseeable future. To meet these demands, next generation wireless networks must support a significant increase in capacity, greater spectral efficiency and decreased energy consumption. To that end, Network Utility Maximization (NUM) theory has been widely explored and established in modeling and studying resource allocation problems in next generation (4G/5G) wireless networks. In parallel, Game Theory is a powerful tool that can be used as a unifying framework to solve resource allocation problems and determine stable solutions (Nash equilibrium points). The combined outcome of NUM and Game Theory considering resource allocation problems in next generation wireless networks is very well aligned with the current efforts for the realization of user’s self-optimization functionalities, envisioned by 3GPP LTE and LTE Advanced efforts and specifications. This talk will describe the formulation of various resource allocation problems in CDMA, SC-FDMA, two-tier femtocell and machine-to-machine wireless networks and propose game theoretic approaches to determine stable solutions supporting user’s autonomicity and self-optimization.
