updates• Current evaluation results
– Obtained 8 curves which are combination of • w/ or w/o 6top housekeeping• Removing worst cell or removing random cell• w/ or w/o interference
– One point that does not make sense is that removeRandomCell works better than removeWorstCell when the number of motes is small.
Reliability(i) worst cell removing (ii) random cell removing
(iii) worst vs random (iv) no interference
Combination of housekeeping and worst cell does not
improve
Combination of housekeeping and
random cell slightly improves
Same performances
Packet drop rate (=1.0- reliability)(i) worst cell removing (ii) random cell removing
(iii) worst vs random (iv) no interference
When numMotes is equal or less than 60, the random is
better than the worst due to
unknown reasons
When numMotes is equal or less than 60,
the random curves are better than the worst curves due to unknown reasons

Next steps• Find condition sets where 6top housekeeping can improve the
reliability– Constant bit rate (pkPeriodVar = 0.0)– Parent Switch with threshold– Overprovision– numCh < 16
• Simulator update needed– More general removeWorstCell function– Parent switch with threshold
