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.
