Abstract:Simple multicast forwarding protocol in the absence of the recipient, the multicast source will be flooded throughout the network, this will lead to unnecessary duplication of data. In order to avoid MANET this problem, the authors propose protocols for multicast forwarding simply an extended method, which based on limited flooding scope and reach all the multicast receivers unicast, multicast source list calculated for each recipient a mix value. With this mix is the standard way with limited options flooding the best combination of unicast to minimize network overhead caused by flooding.
