Mobile Multicast Protocol Based on Dynamic Multicast Agent

According to the principle of mobile multicast algorithm for dynamic multicast Agent,this paper proposes a mobile multicast protocol.It adopts a novel fast multicast swithc mechanism and selects the multicast Agent dynamicly according to the time measurement and distance measurement.Simulation results show that this protocol avoids the frequent reconstruction of multicast delivery tree,decreases the multicast switch delay.It has the near-optimal multicast transfers path and capability of integration with the existing network protocols.
