    • A method for distributing a packet to a plurality of moving nodes comprising receiving a packet containing at least a message, a sender identifier, a location of a sender, an identifier for a relay node and distance from the sender and the relay node, determining if a node receiving the packet is the relay node and immediately distributing the packet to a plurality of moving nodes if the receiving node is the relay node. If the receiving node is not the relay node, the method further comprises steps of waiting a set period of time, determining if a packet is received from a different sender containing the same message, within the period of time and distributing the packet to a plurality of moving nodes if a packet containing the same message is not received within the period of time. The distributed packet includes an identifier for a successive relay node.

    • 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 “k” previous control message cycles The upstream node may be the group header (GH) for the LPG.
    • 本发明提供了用于在VANET中有效控制消息分发的方法。 提供了有效的洪泛机制,以通过所选择的关键节点进行有限数量的重新播放来实现洪水(向每个连接的节点传递消息)的目标。 基于抑制的有效洪泛机制利用光抑制(LS)技术通过在节点观察相同洪泛信息的下游中继时放弃广播消息来减少洪泛中继的数量。 另外,基于中继节点的有效洪泛机制选择中继节点(RN)以形成用于控制消息传递的有效洪泛树。 RN是在“k”个先前的控制消息周期中将至少一个控制消息(例如,成员资格报告(MR))中继到上游节点的节点。 上游节点可以是LPG的组头(GH)。

    • 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.
    • 一种用于路由单播和多播消息的方法和通信设备。 用于路由单播消息的方法包括从组头节点接收包括路由参数的第一控制分组,基于路由参数更新路由表,从组节点接收包括附加路由参数的第二控制分组,更新路由表 基于附加路由参数,并且当两个更新的步骤都完成时,从路由表生成转发表。 基于转发表路由单播消息。 一种用于路由多播消息的方法包括接收多播消息,确定多播消息的组播组目的地是否在组播转发表(MFT)中,确定多播消息是否已经被转发,并且如果消息 以前没有转发,组播组目的地处于MFT中。
