    • Provided is a Media Access Control (MAC) forwarding method for multi-hop routing in a communication system between vehicles. The method includes the steps of: a) receiving a frame from all nodes and checking whether there are duplicate frames; b) partly updating forwarding cache table (FCT) information, or updating SNT information and checking whether a destination address is a corresponding node; c) updating the FCT information, transmitting an Ack signal and transferring the frame to the upper layer, or searching whether the destination address is registered as “d_addr”; d) updating the FCT information and transmitting a delay ACK frame or checking whether the transmitted frame is a flooding frame; and e) updating the FCT information, checking whether the other node does not transmit the “d_ack” and inserting a flooding frame, otherwise, updating the FCT information and abandoning the frame.
    • 提供了一种用于车辆之间的通信系统中的多跳路由的媒体接入控制(MAC)转发方法。 该方法包括以下步骤:a)从所有节点接收帧并检查是否存在重复帧; b)部分更新转发高速缓存表(FCT)信息,或更新SNT信息并检查目的地址是否是对应节点; c)更新FCT信息,发送Ack信号并将帧传送到上层,或者搜索目的地地址是否被注册为“d_addr”; d)更新FCT信息并发送延迟ACK帧或检查所发送的帧是否是泛洪帧; 以及e)更新FCT信息,检查其他节点是否不发送“d_ack”并插入洪泛帧,否则更新FCT信息并放弃该帧。

    • The present invention provides a method and apparatus for assigning a channel in an ad-hoc network, which can minimize beacon collision in the ad-hoc network and prevent channel overlapping or collision, and thus a channel can be efficiently assigned. The method of assigning a channel including: obtaining join order information which is information on the order in which a first node has been joined to a second node, which is a parent node, and level information of the second node in an ad-hoc network; determining a reference value for setting a channel that is to be assigned to the first node based on an address value of the first node, which is determined based on the join order information and the level information, a level value of the first node, a channel value of the second node, which is determined based on the level information, and the join order information; and determining a channel value of the first node by dividing the reference value by the maximum number of usable channels in the ad-hoc network.
    • 本发明提供了一种用于在自组织网络中分配信道的方法和装置,其可以最小化自组织网络中的信标冲突并且防止信道重叠或冲突,从而可以有效地分配信道。 分配频道的方法,包括:获取作为第一节点已加入到第二节点(其为父节点)的顺序的信息的连接顺序信息和自组织网络中的第二节点的级别信息 ; 基于所述第一节点的基于所述连接顺序信息和所述级别信息确定的地址值,确定用于设置要分配给所述第一节点的信道的参考值,所述第一节点的级别值, 基于级别信息确定的第二节点的信道值和连接顺序信息; 以及通过将所述参考值除以所述自组织网络中的可用信道的最大数目来确定所述第一节点的信道值。
