Competition: Energy-Efficient Network Flooding with Channel-Hopping
Philipp Sommer, Yvonne-Anne Pignolet · International Conference on Embedded Wireless Systems and Networks · 2017
We present a communication protocol for fast and reliable dissemination of event messages in short-range wireless networks. Our approach combines fast network flooding using Glossy with a pseudo-random channel-hopping scheme to increase its robustness against external interference. While a Glossy network flood can disseminate events within the wireless network within a few milliseconds, nodes need to be actively listening to the wireless channel in order to synchronize on the start of a Glossy flood. We therefore combine Glossy with a round-based radio duty-cycling scheme to reduce the energy consumption of our system at the expense of increased latency between detection of an event until a new network flood can be initiated.
