Research

Research activities at WiNeMA group are focused on the following themes (present and past):

  • Smart mobility: this activity is aimed at understanding how communication and information technology, and concomitant advances in automotive technology such as self-driving vehicles, can be exploited to provide breakthrough improvements in urban mobility. In particular, we investigate benefits provided by the "sharing economy" in urban transportation, considering both ride sharing, vehicle sharing, and their combination. This activity is undertaken in close cooperation with the Senseable City Lab at Massachusetts Institute of Technology, led by Carlo Ratti.
    In July 2014 Dr Paolo Santi has been entitled as the leader of the newborn Ambient Mobility Lab, a joint initiative between the Senseable City Lab at MIT and the Mobility Innovation Lab at the Fraunhofer Institute for Industrial Engineering IAO. The goal of the Ambient Mobility Lab is to become a global frontrunner as a pioneering institution for 'smart mobility' research to analyze, design, develop and test senseable and sustainable mobility systems in interaction with other future urban systems.
  • Characterization of wireless network scaling laws: in this activity, the goal is to investigate how performance of specific communication paradigms (e.g., broadcast, convergecast, etc.) scales when the size of the network grows larger. In particular, we are interested in characterizing network performance not only in terms of capacity, but also in terms of communication latency.
  • Wireless link scheduling: in this activity, the challenge is to define fast algorithms for scheduling transmissions in a wireless network with provable approximation bounds. Particular emphasis is given to the definition of accurate models for a very complex phenomenon like radio interference. These models are then used to impose interference constraints in the transmission scheduling process. Some of the solutions developed within this line of research have been implemented and tested in a wireless sensor network testbed. This activity is in cooperation with the group lead by Doug Blough at Georgia Tech, US, and the group lead by Samir Das at Stony Brook University, US.
  • MIMO networks: the goal of this activity is to investigate how multi-antenna systems can be used to considerably increase the capacity of a wireless multi-hop network. In particular, the MimoNet project has been recently funded by IIT CNR, whose goal is to define models and to design algorithms for network-level exploitation of MIMO technology in a wireless mesh network. This research activity encompasses not only model definition and algorithm design, but also implementation of the defined models within state-of-the-art network simulators, and realization of the designed algorithms on a Software Defined Radio-based testbed. This activity is in cooperation with the group lead by Doug Blough and the group lead by Mary Ann Ingram at Georgia Tech, US.
  • P2P algorithms for wireless mesh networks: in this activity, the challenge is to define efficient algorithms to enable peer-to-peer resource sharing in a wireless mesh network. In this context, efficiency is measured in terms of communication overhead induced by the creation and maintenance of the peer-to-peer overlay network. The basic idea is to exploit location information and cross-layering to considerably improve performance of popular peer-to-peer protocols (e.g., Chord) which have been designed for an Internet environment. This activity is in cooperation with Claudia Canali at University of Modena and Reggio Emilia, Italy, and with the group lead by Sergio Palazzo at University of Catania, Italy.
  • Vehicular networks: in this activity, techniques based on transmission power control aimed at controlling congestion in a cooperative vehicular communication environment are investigated. Furthermore, integration of the above techniques with multi-hop information dissemination protocols are considered, with the purpose of designing algorithms for the fast and reliable dissemination of safety-critical information in a vehicular ad hoc network. This research activity is in cooperation with the group lead by Hannes Hartenstein at University of Karlsruhe, Germany.
    The group also participated in the IPERMOB project, which has been funded by Regione Toscana. Within IPERMOB, our group was in charge of designing communication protocols for integrating vehicular networks within a metropolitan mobility management system, as well as advanced applications that extract information from the metropolitan mobility system to give the driver a real-time view of traffic and parking conditions.
    Furthermore, WiNeMA group is currently involved in VehiCong project, with the aim of studying congestion in IEEE 802.11p-based vehicular ad-hoc networks. This project has been jointly funded by Regione Toscana and Istituto di Informatica e Telematica and is in cooperation with INTECS SpA.
  • Mobility modeling: in this activity, techniques borrowed from geometric probability are used to analyze structural properties of mobile networks. Furthermore, novel mobility models in which user mobility is driven by the perceived QoS level have been defined.
  • Cooperation in wireless multi hop networks: in this activity, we investigate the effects of non-cooperative node behavior on the performance of networking protocols. In particular, routing protocols are considered, where selfish nodes acting as message forwarders might drop messages in order to save own resources. Some of the research activities within this line have been performed in cooperation with Stephan Eidenbenz at Los Alamos National Labs, US.
  • Topology control: in this activity, we study techniques aimed at keeping the network connected, while at the same maintaing some structural network property such as connectivity. Furthermore, node clustering approaches aimed at simplifying the routing process and/or reducing node energy consumption through sleep/awake scheduling have been studied. This research activity, currently mostly ended, has been performed in cooperation with Doug Blough at Georgia Tech, US, and with Mauro Leoncini at University of Modena and Reggio Emilia, Italy.
