doc.: IEEE /0612r0 Submission Motivation Different Service type has different requirements AP can optimize the system parameters based on the service type May 2012 Wu Tianyu, HuaweiSlide 3 SensorOffloading Duty CircleLongShort Packet SizeShortNormal Power save ReqHigherLower DL/ULUL dominatedMore DL traffic PeriodicityMostly PeriodicMostly bursty Parameters Service Type

doc.: IEEE /0612r0 Submission Parameter Optimization based on Service Type AP can: –Optimize the DTIM interval for STAs with different service type Assign a longer DTIM interval for sensors can enhance the power save performance –Optimize the Max Idle Period for STAs with different service type Sensor STAs may need a longer Max Idle Period –Assign appropriate AID for STAs with different service type If AIDs for sensor STAs with low duty circle are assigned contiguously, there is higher chance for the TIM to have long contiguous 0s. If AIDs for sensor STAs with same periodic duty circle are assigned contiguously, there is higher chance for the TIM to have long contiguous 1s. This may help TIM compression.
