Optimizing the Ad-Hoc Applications in Vehicular Network: A Study
Sumeet Sekhon | Dinesh Kumar 
Abstract: As per today's scenario; wireless networks are becoming more popular day by day as it is difficult for people to constrain their needs to the wired networking. MANET is mobile ad hoc network wherein mobile nodes can communicate with each other through radio waves. It does not need a fixed infrastructure or any centralized control. Vehicular ad-hoc network also called as VANET is a type of MANET that uses vehicles as nodes that communicate with each other. VANET works on the basis of real time system where the vehicles move as nodes and travel with a very high speed on roads. This kind of networks are self-configuring networks composed of a collection of vehicles and elements of roadside structure linked with each other without requiring any infrastructure; sending and receiving information of current traffic situation. Nowadays; Wi-Fi (IEEE 802.11 based) technologies are most commonly used for the initialization of VANET. There are many security issues like authentication; tunnel attacks; intelligent system approach; collision detection; congestion avoidance; communication system approach etc. A number of methods have been proposed to deal with various issues in VANET. Delay is a major issue that has to be dealt with as this may happen due to accidents taking place in VANET which can pose serious problems for smooth networking. Delay has to be reduced in order to transmit the data in time to all the vehicles present in that network.
