vanetrbc_rxdatadb.h

基于NS-2的车辆Ad Hoc网络（VANET）的一个应用层协议框架

/* -------------------------------------------------------------------
 * Vehicular Ad Hoc Networks: Regular Broadcasting of messages.
 * Skeleton for VANET-protocols. This should be considered as an
 * example to create other VANET protocols!
 * Apart from channel load, the "protocol" as it is now does not do
 * anything useful.
