Proposed Solution: PIES - Characteristics
l Achieves fair energy conservation by:
o Putting nodes to sleep for equal time periods
o Providing the routing algorithm with energy threshold info
to help it make fair energy conscious decisions
l Fully distributed algorithm – functionality does not
depend on a node or a set of nodes
l Modular nature – easily integrated with existing
routing algorithms
l Ability to determine with certainty neighbors’ sleep
state
l Configurable in such a way that introduces no
additional traffic to the network
