摘要： A method and communication device for routing unicast and multicast messages. The method for routing a unicast message includes receiving a first control packet including routing parameters from a group header node, updating a routing table based upon the routing parameters, receiving a second control packet including additional routing parameters from a group node, updating the routing table based upon the additional routing parameters and generating a forwarding table from the routing table when both of the updated steps are completed. The unicast message is routed based upon the forwarding table. A method for routing a multicast message comprises receiving the multicast message, determining if a multicast group destination for the multicast message is in a multicast forwarding table (MFT), determining if the multicast message has been previously forwarded and forwarding the multicast message if the message was not previously forwarded and the multicast group destination is in the MFT.

摘要： An ad-hoc wireless network with a roadside network unit (RSU) and a local peer group (LPG). The LPG is formed from a plurality of moving vehicles. The LPG includes a group header node (GH) for managing the LPG. The GH is elected from one of the moving vehicles. The LPG further includes group nodes (GN) designated from the remaining moving vehicles in a given area. Each of the moving vehicles, whether the GH or the GN, communicates with other using routing paths created based upon a first control packet broadcast from the GH and a second control packet broadcast from each of the GN. Each moving vehicle communicates with the RSU using a routing paths created based upon a beacon broadcast by the RSU and a reply signal from each of the moving vehicles. The RSU can also be a member of the LPG and act as GN or GH.

摘要： Network architecture configured for open communication between a plurality of sub-networks. Each of the plurality of sub-networks has a different routable network addressing scheme. The architecture includes at least one broker node adapted to communicate using at least two different routable network addressing schemes. The broker node comprises an identification management module configured to collect peer-application addresses for nodes currently accessing a specific application, the peer-application addresses being associated with a specific application, an address resolution module configured to map each of the peer-application addresses to a sub-network specific routable network address and a network coordination module configured to monitor and coordinate sub-network communication capabilities between the broker node and at least one other broker node and elect a primary broker node for each sub-network which the broker node and at least one other broker node is capable of communication.
