The routing table available in the router is not applicable for the free roaming mobile agent to roam around the network, so each and every server must have the routing information. This paper proposes a model to generate the routing table for the free roaming mobile agent to roam around the network by calculating the link cost between the nodes. Link cost between the servers is measured by the energy consumed to reach the destination. Link cost is measured by the transmission of agent instead of sending the message because here the route is calculated for agent roaming. The cost for transferring the message and the agent differs because of the migration and transfer. In agent transmission, the whole thing will be migrated to the remote host. But in the message transmission, the particular message is transmitted. Routing table in the destination will be generated automatically by the mobile agent while it visits the destination host and the routing table of the source host will be generated after the agent returns to its home (source host).
