So, the main limitations of multicast forwarding are delay and occurrence of duplicate packets which are resolved by enhancing conventional BMRF algorithm.
Figure 6 illustrates the working procedure of the enhanced BMRF forwarding algorithm.
This comparison is given based on multicast algorithms as SMRF, BMRF and proposed EBMRF.
Delay comparison is illustrated in figure 11, by comparing previous SMRF and BMRF multicast forwarding algorithms.
Figure 12 depicts the achievement of higher packet delivery ratio than SMRF and BMRF. In proposed EBMRF as per the increase in number of nodes, the packet delivery ratio is sustained at a constant level.
