Aiming at the nodes limitation and bad expansibility of topology in Bluetooth scatternet formation algorithms,an improved distributed algorithm of Bluetooth scatternet topology formation was proposed by setting up the scatternet topology model and analyzing the network formation approach of BTCP algorithm.A random role scheme was used to form the multi-piconet structure in a short time and a connected scatternet was set up by various methods of merging and recomposing,which can break the limits of nodes poison and those of the number of piconet and node,thus enhances the expansibility of topology.Simulating results show that the proposed algorithm has lower delay of the scatternet formation comparing with BTCP algorithm;it has less number of piconets and algorithm messages without the number limit of 36 for nodes;moreover,it possesses better flexibility without the limitation that all nodes must be in the range of communication.
