We present a communication protocol for fast and reliable dissemination of event messages from multiple sources in short-range wireless networks. Our approach combines round-based fast network flooding using Glossy with a pseudo-random channel-hopping scheme to increase its robustness against external interference. Using a deterministic round-robin schedule, we support multiple source nodes that initiate Glossy flooding in their corresponding round. Furthermore, we combine Glossy with a synchronized 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.
