Abstract

The invention discloses zone multicast routing system and method of vehicular ad hoc network. The zone multicast routing method of the vehicular ad hoc network comprises the following steps: each vehicle mutually sharing respective driving path through wireless communication when vehicles encounter; each vehicle founding a vehicle routing map on the basis of the collected vehicle paths, and the vehicle routing map comprises all collected vehicle driving paths and corresponding covered city roads; the vehicle with data calculating covering capability of encountered vehicles to a target zone when encountering other vehicles and determining whether to transmit the data or not, and transmitting the data if the encountered vehicles have high covering capability; besides, when the data reaching the target zone, conducting transmitting on all encountered vehicles in the target zone. The zone multicast routing system and method of the vehicular ad hoc network can achieve high-efficiency data zone multicast routing.

Description

technical field [0001] The present invention relates to an area multicast routing system and method for a vehicle ad hoc network, in particular to an area multicast routing system and method for a vehicle ad hoc network based on estimation of vehicle coverage capability. Background technique [0002] Vehicle ad hoc network technology is a very promising technology, which is a new type of wireless network composed of mobile vehicles as network nodes, which can support a variety of practical applications. Such as safe driving, traffic information dissemination, environmental monitoring and so on. Vehicle nodes in VANs communicate through short-range radios, such as Dedicated Short-Range Communication (DSRC) technology, with a communication range ranging from tens to hundreds of meters. Each vehicle node has the same status and can become a data source node, a data receiving node, or a routing node to forward data for other vehicles. [0003] The vehicle ad hoc network is dif...
