Energy-Efficient
Schemes - Issues
lMost routing energy-efficient schemes ignored idle
energy consumption in their
analysis
lNon-routing energy-efficient schemes suffered one or
more of the following
issues:
oNo attention given to energy fairness among network
nodes
oUnrealistic assumptions e.g. traffic nodes do not
forward traffic
oAlgorithm design tied to a specific underlying routing
strategy
oLarge impact on the functionality of the underlying
routing scheme
oNo interaction with underlying routing protocol which
results in unnecessary loss of
traffic
oHeuristic methodology in determining neighbors’ sleep
