Most
routing energy-efficient schemes ignored idle energy
|
|
|
consumption
in their analysis
|
|
|
| l |
Non-routing
energy-efficient schemes suffered one or more
|
|
of
the following issues:
|
|
|
|
o |
No
attention given to energy fairness among network nodes
|
|
|
|
o |
Unrealistic
assumptions e.g. traffic nodes do not forward traffic
|
|
|
|
o |
Algorithm
design tied to a specific underlying routing strategy
|
|
|
|
o |
Large
impact on the functionality of the underlying routing
|
|
|
scheme
|
|
|
|
o |
No
interaction with underlying routing protocol which results in
|
|
|
unnecessary
loss of traffic

|
o |
Heuristic
methodology in determining neighbors’ sleep state
