VEHICULAR COMMUNICATION SYSTEM AND ROUTING METHOD THEREOF

Abstract

The invention discloses a vehicular communication system and a routing method thereof. The routing method includes the following steps. When a first relay node of the relay nodes, which locates in a last road slot of each of the road section, receives the route reply packet, the first relay node is configured to obtain a plurality of moving traces of a plurality of specific relay nodes according to the route reply packet; estimate at least one connection life period related to a plurality of specific road slots according to the moving traces; estimate at least one connection available interval of the specific road section according to the at least one connection life period; and append the at least one connection available interval to the route reply packet and forward the route reply packet.
