Vehicular Urban Sensing: Techniques and Applications

There has been growing interest in vehicle to vehicle communications for a broad range of applications ranging from safe driving to content distribution, advertising, commerce and games. One relatively new application is urban sensing. Vehicles monitor the environment, classify the events, e.g., license plates, pollution readings, etc. and exchange metadata with neighbors in a peer-to-peer fashion, creating a distributed index from which mobile users can extract different views. For instance, the Department of Transportation captures traffic statistics; the Department of Health monitors pollutants, and; Law Enforcement Agents investigate crimes. Mobile, vehicular sensing differs radically from conventional, static sensor operations. Vehicles have abundant  battery life, processing power and storage capacity. Moreover, as they move, they continually generate  new data, making conventional sensor data collection techniques inadequate. In this talk we first review promising urban sensing applications; then, we introduce MobEyes, a middleware solution that works for all applications and that, via diffusion of data summaries, creates a distributed index of the sensed data. We discuss various techniques to design and maintain such a distributed index. We propose the use of bioinspired approaches to harvest the index. Finally, we address the issues of privacy of dissemination and of harvesting.


BIOGRAPHY OF Prof. Mario Gerla

Dr. Mario Gerla, Professor, UCLA, Computer Science Dept. Dr. Gerla received his Engineering degree from the Politecnico di Milano, Italy, in 1966 and the M.S. and Ph.D. degrees from UCLA in 1970 and 1973. He became IEEE Fellow in 2002. At UCLA, he was part of a small team that developed the early ARPANET protocols under the guidance of Prof. Leonard Kleinrock. He worked at Network Analysis Corporation, New York, from 1973 to 1976, transferring the ARPANET technology to several Government and Commercial Networks. He joined the Faculty of the Computer Science Department at UCLA in 1976, where he is now Professor. At UCLA he has designed and implemented some of the most popular and cited network protocols for ad hoc wireless networks including distributed clustering, multicast (ODMRP and CODECast) and transport (TCP Westwood) under DARPA and NSF grants. He has lead the $12M, 6 year ONR MINUTEMAN project, designing the next generation scalable airborne Internet for tactical and homeland defense scenarios. He is now leading two advanced wireless network projects under ARMY and IBM funding. In the commercial network scenario, with NSF and Industry sponsorship, he has led the development of vehicular communications for safe navigation, urban sensing and location awareness. A parallel research activity covers personal P2P communications including cooperative, networked medical monitoring (see http://www.cs.ucla.edu/NRL for recent publications).

Realizing the “Anything Anybody Anywhere Anyhow Anytime” Ultimate Wireless Revolution

Over the last two decades, wireless communications has witnessed an explosive growth and without any doubt has revolutionized many aspects of our daily lives. In this short time period, wireless networks have advanced through three generations (1G, 2G, and 3G), and many licensed or license-free wireless technologies such as WiMAX and WiFi have also emerged to complement the capabilities of cellular networks.  Recently, there has been growing demand for ubiquitous connectivity to a plethora of data services from portable computer-enhanced devices such as personal digital assistants, laptops, home and office appliances, cellular phones, and information terminals.  This along with the expected explosive growth of high-speed access to the Internet in public spaces, homes, and enterprises is fueling the demand for broadband communications with low-cost and low-power computing devices. Advances in microelectronic and communications technologies have also made possible the development of a revolutionary paradigm, Cognitive Ubiquitous Communications, where cognitive agents and communications devices within an environment-aware, reconfigurable, agile, and open infrastructure are envisioned to be available in the next 15 years.  A key requirement for these future wireless systems is their ability to provide broadband IP-connectivity with end-to-end Quality of Service (QoS), a high network capacity, and throughput at a low cost. Other key requirements include improved latency, scalable bandwidth, and inter-system mobility and management. 

This talk will discuss the features of the future world of agile wireless networks where convergence will abolish borders inside the digital world and where more and more services will be using different technologies, often supported by intelligent multimodal terminals over a converged IP network regardless of the access technology.  We shall also discuss some of the technical issues and challenges as well as describe some of the key competing technologies and solutions needed to realize the “Anything Anybody Anywhere Anyhow Anytime” ultimate wireless dream.
