System and method for trans-medium address resolution on an ad-hoc network with at least one highly disconnected medium having multiple access points to other media
First Claim
1. A method for controlling a plurality of nodes in an ad-hoc communications network to perform address resolution protocol (ARP) on a frame by frame basis, said plurality being adapted to transmit and receive data packets to and from other nodes in said ad-hoc network, said method comprising:
- controlling a first node of said plurality to generate an address resolution protocol (ARP) request for a first media access control (MAC) address corresponding to an optimum intelligent access point (IAP) for sending a medium frame;
controlling a second node to receive and identify said request, and provide a second MAC address, adapted to instruct said first node that said requested first MAC address is a dynamic link address; and
controlling said first node to receive said second MAC address and in response, route said medium frame to a current IAP.

Abstract
A system and method for providing a mechanism for trans-medium address resolution on a network with at least one highly disconnected medium having multiple access points to other media. The system and method provides a “unique” media access control (MAC) address in address resolution protocol (ARP) for mobile nodes in an ad-hoc network, correctly identifying the optimum intelligent access point (IAP) for node communication where the optimum IAP changes more rapidly than traditional address updating may be able to accommodate. Medium layer routing protocols recognize medium frames addressed with this unique MAC address should be routed to the currently associated IAP, whichever IAP that might be at the moment the frame is sent.

11. An apparatus adapted to perform address resolution protocol (ARP) on a frame by frame basis, and being further adapted to transmit and receive data packets to and from other nodes in said ad-hoc network, comprising:
-
a first node, adapted to generate an address resolution protocol (ARP) request for a first media access control (MAC) address corresponding to an optimum intelligent access point (IAP) for sending a medium frame;
a second node, adapted to receive and identify said request, and to provide a second MAC address adapted to instruct said first node that said requested first MAC address is a dynamic link address; and
said first node being further adapted to receive said second MAC address and in response, to route said medium frame to a current IAP. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
