vanetrbc.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.
 *
 * Dan Jungels ([e-mail])
 * LCA - EPFL
 *
 *
 * Header file for the main protocol
 * Originally written for ns2.29
 *
 * 2005-12-15: release of first version (dj)
 * 2005-12-23: update and cleanup, public release (dj)
