Efficient algorithm for mobile multicast using anycast group

The authors present a novel and efficient multicast algorithm that aims to reduce delay and communication cost for the registration between mobile nod es and mobility agents and solicitation for foreign agent services based on the mobile IP. The protocol applies anycast group technology to support mu lticast transmissions for both mobile nodes and home/foreign agents. Mobile hosts use anycast tunnelling to connect to the nearest available home/fore ign agent where an agent is able to forward the multicast messages by selec ting an anycast route to a multicast router so as to reduce the end-to-end delay. The performance analysis and experiments demonstrated that the propo sed algorithm is able to enhance the performance over existing remote subsc ription and bidirectional tunnelling approaches regardless of the locations of mobile nodes/hosts.
