l“Protocol Independent Energy Saving”, PIES
lAchieves fair energy conservation by:
oPutting nodes to sleep for equal time periods.
oProviding the routing algorithm with energy threshold info to help it make fair energy conscious
decisions
lFully distributed algorithm – functionality does not depend on a node or a set of nodes
lModular nature – easily integrated with existing routing algorithms
lDeterministic sleep pattern enables nodes to determine mathematically neighbors’ sleep state
lConfigurable in such a way that introduces no additional traffic to the network
