Publication number: 20130315099Abstract: 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.Type: ApplicationFiled: July 23, 2013Publication date: November 28, 2013Applicant: Telcordia Techmologies, Inc.Inventors: Wai Chen, Taek-Jin Kwon, Toshiro Hikita, Ryokichi Onishi, John Lee

Patent number: 8351417Abstract: The present invention provides methods for efficient control message distribution in a VANET. Efficient flooding mechanisms are provided to fulfill the objective of flooding (delivering a message to every connected node) with a limited number of re-broadcasting by selected key nodes. A suppression-based efficient flooding mechanism utilizes a Light Suppression (LS) technique to reduce the number of flooding relays by giving up the broadcasting of a flooding message when a node observes downstream relay of the same flooding message. Additionally, a relay-node based efficient flooding mechanism selects Relay Nodes (RN) to form an efficient flooding tree for control message delivery. RNs are nodes that relay at least one control message, for instance a Membership Report (MR) to the upstream node in âkâ previous control message cycles The upstream node may be the group header (GH) for the LPG.Type: GrantFiled: May 14, 2008Date of Patent: January 8, 2013Assignees: Telcordia Technologies, Inc., Toyota InfoTechnology Center, U.S.A., Inc.Inventors: Wai Chen, Taek Jin Kwon, John Lee, Ryokichi Onishi, Toshiro Hikita

Patent number: 8254301Abstract: A method for establishing and maintaining the network and a corresponding ad-hoc moving-device to moving-device network having a plurality of moving-devices grouped into a Local Peer Group (LPG) is disclosed. A group header node (GH) is selected from the plurality of moving wireless devices in the LPG. The GH controls and manages the LPG by broadcasting a plurality of control messages, including a heartbeat message at a fixed interval. The LPG also includes at least one group node (GN). The at least one GN can communicate with the GH via a network link created between the at least one GN and the GH. The GNs join the LPG via the GH. If there is more then one GH in an LPG, header resolution occurs to select only one GH.Type: GrantFiled: November 22, 2005Date of Patent: August 28, 2012Assignees: Telcordia Technologies, Inc., Toyota Infotechnology Center, U.S.A, Inc.Inventors: Wai Chen, Jasmine Chennikara-Varghese, Marcus Pang, Shengwei Cai, Toshiro Hikita
