| For maximizing the energy efficiency in a
wireless network, we propose two forwarding schemes termed
single-link and multi-link energy-efficient forwarding that trade
off delivery ratios against energy costs. Multi-link forwarding
improves the network performance substantially by addressing
multiple receivers at once during the packet forwarding process.
If the first forwarding node does not receive a packet correctly,
other nodes may act as backup nodes and perform the forwarding
instead. By means of mathematical analyses, we derive how the
energy efficiency of a forwarding path can be computed and how a
forwarding tree is established. Routing cycles are explicitly
taken into account and prevented by means of sequence numbers.
Simulations and real-world experiments provide a comparison to
other reference strategies, showing a superior performance of our
forwarding scheme in terms of energy efficiency. |
