INTRODUCTIONAd hoc networks

-Wireless devices

-No centralized infrastructure

Multi hop ad hoc networks

-Mobile nodes

Arbitrary and temporary network topologies

Used in disaster recovery environments

Single hop ad hoc networks

-Same transmission range

VANET

Mesh Networks

EXISTING SYSTEM

1. TIMERS

Fixed time interval

2. SENSORSCoils placed in loops in the grooves in the road

Inductive loops

Vehicles over the loop

Inductance increases

Drawbacks associated with both the systems


6/21

PROPOSED SYSTEM

Simulating multi hop ad hoc network

Peer-to peer

Multi hop

Exchanging status info

Implemented usingJava

Networking capabilities

Graphical Interface


7/21

TOKEN RING PROTOCOL

Special 3-byte frame-token

Token circulating around the ringNode holding the token allowed to transmit for a fixed

duration.
