In a wireless network having a plurality of nodes which roam about the network, a method for routing data packets among the nodes whereby each of the nodes carries out the steps of maintaining a list of nodes which are reachable through the node based on advertisements received from other nodes; advertising to other nodes the list of nodes which are reachable through the node; and when receiving a data packet for which the node is not the ultimate destination, forwarding the data packet towards the ultimate destination based on the list of nodes. |

DETAILED DESCRIPTION The present invention provides a network in which mobile devices themselves serve as routers of data packets.
Each mobile device represents a node in the network.
The nodes advertise a list of nodes which are reachable through their interface(s).
When a node receives a data packet for which it is not the ultimate destination, it looks up a next hop link address from its list of reachable nodes, and forwards the data packet to that address.
According to one aspect of the invention, in a wireless network having a plurality of nodes which roam about the network, a method for routing data packets among the nodes is provided whereby at least one node carries out the steps of: maintaining a list of nodes which are reachable through the node based on communication received from other nodes; and when receiving data for which the node is not the ultimate destination, attempting to forward the data towards the ultimate destination based on the list of nodes.
According to another aspect of the invention, in a wireless network having a plurality of nodes which roam about the network, a method for routing data packets among the nodes is provided whereby each of the nodes carries out the steps of: maintaining a list of nodes which are reachable through the node based on advertisements received from other nodes; advertising to other nodes the list of nodes which are reachable through the node; and when receiving data for which the node is not the ultimate destination, forwarding the data towards the ultimate destination based on the list of nodes.
According to still another aspect of the invention, a method of communicating routing information in a cellular communication system is provided, the method including the steps of: receiving at a first mobile node communication from a second mobile node operating within direct communication range; adding the second mobile node to a routing table maintained by the first mobile node; and transmitting from the first mobile node, for receipt by at least one other mobile node which may be operating within direct communication range of the first mobile node, at least a portion of the routing table including information related to the second mobile node
