Abstract: In recent years online gaming where multiple players from different location participate through internet in same session. Multicasting is very suitable in such environment. Multicasting is a key concept for modern communication. A message is sent from a source host to a group of destination hosts. Communication link is used as a path to receivers. Multicasting uses several multicast routing protocols for forwarding messages from source host to destination hosts. In recent years packet radio has gained much popularity for host to host communication. Power constraints and scarce bandwidth are the major challenges for routing protocols. We performed the comparative study and analysis of the Reactive and Proactive routing strategies for wired ad hoc networks. In this paper we are showing the comparison between the Core Based Tree and Centralized routing strategies.
