Abstract:

Sleep scheduling is a widely-used mechanism for saving energy and prolonging network lifetime. However, in extremely low duty-cycled wireless sensor networks, achieving high performance of end-to-end packet delivery delay requires a carefully-designed routing method. We first present an implementation of random duty cycling, and then design a distributed routing method. We consider both forwarding progresses and transmission delay in the selection of next hop node when making forwarding decisions. Theoretical analyses and simulation results show that our routing method has advantages in terms of latency and hop distances, compared to the existing methods.

Key words: wireless sensor network (WSN), randomized duty-cycling, routing algorithm
