| Energy-efficient forwarding becomes important
if resources and battery lifetime are limited such as in Wireless
Sensor Networks. Although widely used, simple hop-based
forwarding along a path from one node towards a sink can be very
inefficient in terms of delivery rate as well as energy
efficiency, especially in lossy environments. We will show that
just minimizing the expected number of transmissions within the
network is not always the most efficient forwarding strategy.
Using a realistic link loss model, we derive two new forwarding
schemes named Single-Link and Multi-Link Energy-Efficient
Forwarding that trade off delivery rate and energy costs best by
maximizing energy efficiency. Multi-Link Forwarding further
benefits from addressing multiple receivers during packet
forwarding, instead of a single one. By mathematical analyses,
extensive simulations, and experimental experiments we contrast
the performance of our approaches against a comprehensive
framework of different forwarding strategies. |
