Low-power, memory-ecient networking mechanisms are an essential part of the Internet of Things (IoT) and thus, fundamental to Smart Health applications lever-aging IoT. This paper presents Bloom-RPL, an optimization of RPL, the standard low-power routing protocol for IoT. This paper evaluates Bloom-RPL both on an emulator, and on an IoT testbed using real hardware , to conclude that Bloom-RPL dramatically improves RPL's link check scalability with respect to both IoT device density and convergence time needed to detect a link break.
