Abstract
An system and method for handling broadcast network requests for auto-configuration and discovery of IP to MAC address mappings and gateway presence in wireless peer-to-peer ad-hoc routing networks. The significant portion of a node's IP address is calculated by applying a hashing function to the six-byte hardware (MAC) address. The significant portion is appended to routing advertisements, and thereby propagates passively to other network nodes. DHCP and ARP requests, as well as other broadcast type requests, are handled by the local network stack of a node, without requiring a broadcast transmission over the wireless channel.
