Minimum Transmission Power Routing (MTPR) [5] finds
total minimum transmission power by simply putting each
neighbor node’s transmission power together one by one from
source node to destination node. The weakness of MTPR is
that it has a chance to get longer hop path than any other
algorithms since it only see the transmission power, and it also
could have an energy poor node included in their chosen path.
With MTPR, it is hard to get an energy optimal path, so it is
clear that battery poor node in the path also should be
considered as well as total transmission power sum when
configuring energy efficient path.
