This chapter addresses the problem of energy-efficient data forwarding in wireless sensor networks. It presents our solution to this problem for always-on wireless sensor networks, where the sensors are active all the time. Specifically, it investigates both short-range and long-range data forwarding schemes on always-on sensors and provides several theoretical and simulation results. It shows that short-range data forwarding scheme is more appropriate than long-range data forwarding scheme to save energy of the sensors and promote the longevity of wireless sensor networks with scarce energy resources. Our proposed solution is based on the geometric properties of Delaunay triangulation.
