| As shown in previous work, energy-efficient
forwarding is a very promising forwarding strategy since it
trades off the delivery rate of nodes sending data to a sink node
and the required energy in the network very well. However,
although forwarding paths might be energy-efficient, this does
not have to extend the lifetime of the network. Some nodes may
consume more energy than others, increasing the probability of
network partitions. Thus, algorithms maximizing the lifetime were
proposed. However, only considering the lifetime need not to
achieve good delivery rates and a low energy consumption. The
contribution of this paper is a forwarding metric that
incorporates the end-to-end delivery rate, the required energy
costs, and in addition the residual energy of nodes being on the
forwarding path. Using simulations, we compare our scheme with
forwarding strategies based on other metrics and give insights on
its performance characteristics. |
