The aim of this activity is to investigate multicasting strategies in a MANET. The focus is on the Simplified Multicast Forwarding (SMF), which provides an optimized flooding mechanism in MANET environments to efficiently propagate multicast packets. The design accounts for the unique nature and behavior of MANET interfaces and takes advantage of efficient relay set algorithms previously designed and applied in the MANET unicast routing control plane. The design accounts for interoperability with the wired domain. In order to be more useful in a broader range of scenarios, the multicast data to and from a more fixed infrastructure. Algorithms are being developed to support multiple multicast gateways, as they are required both to join multicast groups on behalf of the MANET, as well as to forward multicast data packets between the networks themselves and detecting duplicate packets entering the MANET.
