One flood to route them all: ultra-fast convergecast of concurrent flows over UWB
SenSys '20: Proceedings of the 18th Conference on Embedded Networked Sensor SystemsPages 179–191https://doi.org/10.1145/3384419.3430715Concurrent transmissions (CTX) enable low latency, high reliability, and energy efficiency. Nevertheless, existing protocols typically exploit CTX via the Glossy system, whose fixed-length network-wide floods are entirely dedicated to disseminating a ...

Poster: Cross-Layer Optimization for Low-power Wireless Coexistence
SenSys '15: Proceedings of the 13th ACM Conference on Embedded Networked Sensor SystemsPages 443–444https://doi.org/10.1145/2809695.2817905We present a system that leverages physical layer features to combat Cross-Technology Interference (CTI) in low-power wireless networks. Our system incorporates: (i) a lightweight interference detection mechanism for low-power radios that recognizes the ...

Strawman: resolving collisions in bursty low-power wireless networks
IPSN '12: Proceedings of the 11th international conference on Information Processing in Sensor NetworksPages 161–172https://doi.org/10.1145/2185677.2185729Low-power wireless networks must leverage radio duty cycling to reduce energy consumption, but duty cycling drastically increases the risk of radio collisions, resulting in power-expensive retransmissions or data loss. We present Strawman, a contention ...

The politecast communication primitive for low-power wireless
ACM SIGCOMM Computer Communication Review (SIGCOMM-CCR), Volume 41, Issue 2Pages 31–37https://doi.org/10.1145/1971162.1971167In low-power wireless networks, nodes need to duty cycle their radio transceivers to achieve a long system lifetime. Counter-intuitively, in such networks broadcast becomes ex- pensive in terms of energy and bandwidth since all neighbors must be woken ...
