Federico Ferrari, ETH Zurich: Low-Power Wireless Bus

Low-Power Wireless Bus: a Bus for Low-Power Wireless Networks

Low-power wireless applications that have emerged in recent years increasingly employ mixed installations of static and mobile devices and are often characterized by a blend of traffic patterns. A common approach to meet their diverse requirements is to form ensembles of multiple communication protocols, each designed to support specific traffic patterns in distinct scenarios. Several studies showed that this is often detrimental to system performance, as protocols that were designed in isolation need to operate concurrently.

In this talk the speaker presents the Low-Power Wireless Bus (LWB), a communication protocol that provides a unified and simple solution for multiple communication patterns and mobile nodes immersed in static infrastructures. By using exclusively fast Glossy network floods for communication and globally scheduling every flood, LWB turns a multi-hop wireless network into a shared bus where all nodes receive all packets. Because it keeps no topology-dependent state, LWB is also highly resilient to topology changes due to interference or mobility. Extensive testbed experiments showed that LWB is highly reliable and efficient under a wide range of traffic loads, performs comparably or significantly better than the state of the art in all tested scenarios, and supports mobile nodes with no performance loss.


Federico Ferrari is a final-year PhD student at the Computer Engineering and Networks Laboratory, ETH Zurich, under the supervision of professor Lothar Thiele. His research focuses mainly on the design and implementation of reliable and efficient communication protocols for low-power wireless networks. He has published several papers in top-level sensor network conferences, including ACM/IEEE IPSN and ACM SenSys. Two of these publications received the best paper and best paper runner-up awards at IPSN '11 and IPSN '12, respectively.
