Improving throughput of bluetooth scatternet by SAR policies
Zuang Yi-qi · Computer Engineering and Applications Journal · 2007
In a bluetooth piconet,the master essentially controls the channel.Due to an absence of coordination between independent masters while accessing the wireless medium,devices will encounter high packet interference if several piconets are simultaneously operating in the same area and the throughput of the devices is decreasing.To alleviate the impact,an efficient method is proposed by interference-aware SAR(Segmentation/Reassembling) policies.Through comparing the frequency hopping sequence with others,the piconet can aware when the interference happens.Then it can avoid the collision of slots using the data packets segmentation and reassembling policies.Form the simulation,we find the method can improve the data throughput of bluetooth scatternet evidently.
