Abstract
A system and method for providing a congestion optimized address resolution protocol (ARP) for a wireless ad-hoc network. The system and method enables a node in the wireless ad-hoc network to issue an ARP request without the need to broadcast the request to all of the nodes in the wireless ad-hoc network, to thus minimize radio traffic on the wireless ad-hoc network for handling the ARP request. The node includes an address resolution protocol module which is adapted to generate an ARP request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, and a transceiver which is adapted to transmit the ARP request for delivery to an access point of a network portion, such as a core LAN of the network, without broadcasting the ARP request to a plurality of other nodes in the wireless ad-hoc network. The transceiver can transmit the ARP request to the access point directly or via other nodes in the wireless ad-hoc network.
