This paper discusses online power­aware routing in large
sensor networks. We seek to optimize the lifetime of the
network. We develop an approximation algorithm called
max­min zPmin that has a good empirical competitive ra­
tio. To ensure scalability, we introduce a hierarchical algo­
rithm, which is called zone­based routing.
The proliferation of low­power analog and digital electronics
has created huge opportunities for the field of wireless com­
puting. It is now possible to deploy hundreds of devices of
low computation, communication and battery power. They
can create ad hoc networks and be used as distributed sen­
sors to monitor large geographical areas, as communica­
tion enables for field operations, or as grids of computation.
