    Abstract: With the ever increasing demand in multimedia transmissions 
  such as video, audio, image and text, researchers are in need to check the scalability, 
  reliability and the quality of service in heterogeneous networks using multicasting 
  protocols. Researchers have used the Kerberos authentication protocol to enhance 
  the security of the network as the nodes in the network are increased. Three 
  algorithms, Dvmrp, Ant Colony algorithm and Link State algorithm were analyzed 
  for different multimedia with increase in nodes. Different metrics were used 
  and calculated. The heuristic approach for different multimedia algorithms has 
  a significant improvement in performance over earlier approach.
