In a recent report, market research firm ONWorld predicts that the global market for wireless sensor networks (WSNs) will grow tenfold by 2011. At the same time, ONWorld also identifies ease of programming as the major barrier to a widespread adoption of WSNs. In this talk, we present our research on programming abstractions for WSNs and its application in two novel, real-world scenarios: monitoring the structural integrity of heritage buildings and adaptive lighting in road tunnels. In the former setting, WSN nodes are employed to gather vibration, deformation, temperature, and humidity data and to make them available to structural engineers to assess the building’s conditions. The latter application aims at performing fine-grained control of the light intensity in road tunnels to reduce maintenance costs and improve safety. We are building both systems on top of the TeenyLIME middleware we developed, which greatly simplifies the programming task by providing higher-level abstractions to WSN developers. We report on our experiences in designing, implementing, and testing these systems, and present early performance results.

Bio: Luca Mottola holds a Ph.D. in Computer Engineering from Politecnico di Milano (Italy) obtained in 2008 with the thesis “Programming Wireless Sensor Networks: from Physical to Logical Neighborhoods’’. He is now a post-doctoral researcher at the Bruno Kessler Foundation in Trento (Italy), and he will join the Swedish Institute of Computer Science (SICS) next year. Along with G.P. Picco, in 2007 he received the Best Demo Award at the Int. Conf. on Sensor Systems (SenSys). His research interests include programming abstractions, distributed computing, routing in sensor networks, and formal verification of distributed software architectures. More information at
