Abstract
The present invention provides a system and method for multihop packet forwarding within a multihop wireless communication network. The method uses a data frame format including at least the four address fields to forward packets in a multihop wireless network. The method includes generating a route request packet at a routable device in response to receiving a packet destined for an unknown destination. The route request packet includes an originating device field including an address of an originating device, wherein the originating device generated the packet originally; and a source field, wherein the source field includes an address of the first routable device which generated the route request packet.
