Tree Zone Orieted Logic Using Geographic Protocol Over MANET
In mobile ad Hoc network, group communications are different form. Multicast is a fundamental service for supporting information exchanges and collaborative task execution among a group of users. There are several multicast routing protocols in MANET have been shown to large overhead due to high networks dynamic topology. A number of on-demand multicast routing protocols have been proposed, but each also relies on significant periodic (non-on-demand) behavior within portions of the protocol. To overcome these limitations the protocol termed as SODMRP (On Demand Multicast Routing Protocol) proposes a novel zone based geographic multicast protocol. Several virtual architectures are used in this protocol that avoids the difficulty in group membership management, packet forwarding and maintenance.
