Research Of Bluetooth Scheduling Policy

We mainly dissertate the scheduling policy in a piconet which is constructed by severel bluetooth devices here.As we all know,bluetooth devices are used widly and the bluetooth network topology is more and more complex.For example,in a bluetooth scatternet,there may be dozens of bluetooth devices,in every piconet,there are seven bluetooth devices at most,we can't use the Round Robin to schedule it because the Round Robin policy has poor efficiency,otherwise the master driven TDD mode which used in bluetooth system also has some special request. So we must use a new policy to schedule the bluetooth system.To get a new scheduleing policy,we first analyse some existing scheduling policy,such as RR,PP,KFP and HOL PP by using the probability theory and the queue theory,find the facts which have relation with their performance,then we use the progress above to develop a new scheduling from HOL PP,finally,we do a simulation,from it we find the new policy works more efficiency than HOL PP.
