GasNet is a sensor network for real-timely monitoring the gas leak in residential buildings, in order to efficiently protect the buildings from gas leak explosion. GasNet provides low-latency and reliable gas leak ALARM message delivery in complicated RF environments. It does so through ROAP, a novel opportunistic forwarding mechanism considering link correlation. ROAP leverages a hop tree in opportunistic forwarder list selection to ensure the shortest hops to the sink. Furthermore, link

We implement the prototype of GasNet in campus testbed and evaluate its performance via extensive experiments. The experiment results show that ROAP achieves 100% gas leak ALARM message delivery in low latency.
