ABSTRACT:
This paper
investigates the problem of energy consumption in wireless sensor networks.
Wireless sensor nodes deployed in harsh environment where the conditions change
drastically suffer from sudden changes in link quality and node status. The
end-to-end delay of each sensor node varies due to the variation of link
quality and node status. On the other hand, the sensor nodes are supplied with
limited energy and it is a great concern to extend the network lifetime. To
cope with those problems, this paper proposes a novel and simple routing
metric, predicted remaining deliveries (PRD), combining
parameters, including the residual energy, link quality, end-to-end delay, and distance
together to achieve better network performance. PRD assigns weights to
individual links as well as end-to-end delay, so as to reflect the node status
in the long run of the network. Large-scale simulation results demonstrate that
PRD performs better than the widely used ETX metric as well as other two
metrics devised recently in terms of energy consumption and end-to-end delay,
while guaranteeing packet delivery ratio.
