Abstract
This paper discusses several distributed power
aware routing protocols in wireless adhoc networks
(especially sensor networks). We seek to optimize the
lifetime of the network. We have developed three dis
tributed poweraware algorithms and analyzed their ef
ficiency in terms of the number of message broadcasts
and the overall network lifetime modeled as the time
to the first message that can not be sent. These are:
(1) a distributed min Power algorithm (modeled on a
distributed version of Dijkstra's algorithm), (2) a dis
tributed maxmin algorithm, and (3) the distributed ver
sion of our the centralized online maxmin zPmin al
gorithm presented in [12]. The first two algorithms are
