Vanet Projects

Concepts involved in vanet network projects in NS2 Simulation.

• To improve and road safety.
• Location-based services
• Handling attacks on vehicular network.
• Traffic management.
• Find out optimized route.

Characteristics of VANET:

• Rapidly changing network topology.
• Provide sufficient energy.
• Wireless communication.
• Better physical protection.
• Frequent exchange of information.
• Time critical.
• Unbounded network size.
• Support high mobility.

Applications of VANET:

• Internet connectivity.
• Collision avoidance.
• Traffic optimization.
• Peer to peer applications.
• Cooperative driving.

Sample code for vanet Projects in NS2:
MD6 is an encryption algorithm, which is used for providing security in vanet.
void md6_write( void *context, const void *inbuf_arg , size_t inlen)
{
const unsigned char *inbuf = (const unsigned char *)inbuf_arg;
md6_CONTEXT *hd =(md6_CONTEXT *) context;

if( hd->count == 64 )Â /* flush the buffer */
{

transform( hd, hd->buf );
hd->count = 0;
hd->nblocks++;

}
if( !inbuf )
return;

if( hd->count )
{
for( ; inlen && hd->count < 64; inlen– ) hd->buf[hd->count++] = *inbuf++;
md6_write( hd, NULL, 0 );
if( !inlen )
return;
