Design and investigation of scalable multicast recursive protocols for wired and wireless ad hoc networks

The performance analysis shows that SReM scales well when the multicast group size
becomes large. The results show that SReM performs a fixed header size in data packets
where the header size for Xcast+ protocol increases exponentially when the group size
increases. These results show that SReM improves the scalability feature in networks. Other
results obtained shows that SReM performs less end to end delay and overhead in addition to
scalability feature.

SReM is a scalable multicast protocol for fixed networks. The scalability issue is an
important feature for wireless networks. In the next chapter, the mobility feature is added and
proposed two new scalable protocols. These proposed protocols are an extension for SReM,
this extension makes the new protocol able to guarantee the new features in wireless and
wireless ad hoc networks.
