Effect of sleep schedules on the one-hop packet delay. In simulations, receivers R1 and R2 both have a fixed sleep period of 100 slots in their working schedule, and sender S generates around 1000 packets in average. The delay of a packet is the difference from its creation time point to its successful reception time point, including the time for retransmissions. a Three different duty-cycled schedules. b Delay performance under different schedules and link qualities
