Abstract
In the present technique of a communication system (100), an address of a forwarding agent (114) linked to a receiver node (112) is detected to provide a discovered address. The discovered address is then used to establish a direct route with the forwarding agent of the receiver node for subsequent communications between a sender node (104) and the receiver node.

11. A system comprising:
-
a plurality of nodes capable of wireless communication; a first mobility agent linked to a sender node from the plurality of nodes requesting communication with a receiver node from the plurality of nodes, wherein the mobility agent forwards data packets for the sender node; a second mobility agent linked to the receiver node, wherein the second mobility agent forwards data packets for the receiver node; and wherein the first mobility agent detects an address of the second mobility agent to provide a discovered address and establishes a direct route with the second mobility agent using the discovered address for subsequent communications between the sender node and the receiver node.
