Mobile Multicast

Posted by OurTech Team | Friday, October 15, 2010 | Category: , |

Multicast is defined as a one-to-many communication pattern where multiple destinations receive identical datagrams transmitted from a source. Without multicast routing protocols, the source node should transmit multiple one-to-one (unicast) datagrams for multiple destinations, which consumes valuable network resources, e.g., bandwidth. Thus, multicasting offers efficient multiple destination delivery and robust unknown destination delivery. 

 When providing multicasting of mobile hosts, several issues should be considered: 

�� Dynamic Group Membership 
�� Dynamic Member Location 
�� Multicast Delivery Tree 
�� Reliable Multicast Service
