Kunz: Energy-Efficient MANET Routing: Ideal vs. Realistic
Performance
Conclusions
,Accuracy
of state information does matter
–Realistic
versions always performed poorer than ideal versions of the same
protocol variant
,Performance
loss due to inaccurate state information can be as high as 10%
,Initially
exploration: some of the state information is really old (in excess of 20 seconds) and therefore very
inaccurate
–In particular
under high traffic load: control messages sometimes get lost
,Future
work
–Explore
sources/reasons for inaccuracy in more depth
–Explore ways to
increase accuracy

2007: paper on “smart prediction”, which works well for monotonic state information
such as residual energy level
,Probing
old information adds more control messages to the network and does not help
