Bluetooth is a wireless, short-range, low-cost communication technology.The multicast communication is an efficient way of distributing a data packet to a group of receivers.This paper presents a formation approach that generates a virtual scatternet (VSm) for realizing the multicast communication mechanism in Bluetooth networks.The proposed VSm scheme can construct a multi-source multicast tree based on the core-based tree concept.Moreover, simulations were conducted to evaluate the performance of the VSm scheme regarding to several critical factors, such a network size and packet arrival rate.The simulation results show that the virtual scatternet has a smaller tree depth and shorter transmission delay than the traditional flooding scheme.However, the traffic loading at the core node is heavy and the lifetime of the multicast tree is critical.
