...in low-duty-cycle networks, sensors stay dormant most of time to save their energy and wake up based on their needs. such a technique, while prolonging the network lifetime, sets excessive challenges for efficient flooding within the network. tailored for obtaining short delay in low-duty-cycle networks, recently proposed flooding protocols have...
