MATLAB源码用于VANET仿真的测试和仿真。

简介：
` Originally employed reactive protocols were not initially conceived with the consideration of the pronounced mobility inherent during route discovery processes. Consequently, frequent dynamic alterations within VANETs – often triggered by network disruptions – resulted in exceedingly frequent broadcasting and widespread flooding of the entire network, necessitating repeated attempts to establish new routes. Furthermore, the initial establishment of routing pathways demanded a considerable period, and this inherent latency could readily disrupt overall system performance. Considering these factors, conventional reactive protocols, in their present form, are generally unsuitable for time-sensitive applications such as cooperative collision avoidance (CCA). Cooperative Collision Avoidance represents a crucial category of safety applications within VANETs, specifically designed to provide drivers with earlier warnings through vehicle-to-vehicle (V2V) communication [13]. Ad Hoc On Demand Distance Vector (AODV) is a reactive routing protocol that supports both unicast and multicast functionalities. Within AODV, mirroring the behavior of all reactive protocols, topology information is only transmitted by nodes in response to a specific need. When a source node requires data transmission, it initially propagates a RREQ message, which is then forwarded by intermediate nodes until the intended destination is located. Upon reaching the destination, a route reply message is unicast back to the source node if either the receiver utilizes the requested address or possesses an established route to that address. This repository offers a MATLAB simulation of a VANET environment and presents results comparisons focusing on metrics such as throughput and packet drop ratio.
