Abstract
Nowadays, the world is in ones pocket in the form of tablet pc and other hand held devices. Now the main challenge in modern world is to provide mobility while remaining in the era of real time data communication. Currently lot of work is going on in this regard and the focus is on VANET. Vehicular ad-hoc network is technology which maintains vehicle to vehicle data communication as well as vehicle to network infrastructure communication. These two aspects of VANET make the modern day communication more efficient and effective. By establishing connection with an infrastructure user can use the internet and can communicate to the world while moving. On the other hand in vehicle to vehicle contact it can share certain data or situation with the other vehicle like information about road condition, accident and circumstances related to surroundings. Now this will make the decisions of other person autonomous in a sense that by getting the latest information from next vehicle the decision will be more intelligent that will avoid any abrupt situation. This will lead us to an intelligent system. The challenge in VANET is to provide a quality oriented internet service due to mobility. Because mobility introduces the concept of handoffs, which results in delay in throughput and frequent packet loss. This paper will focus on different handoff techniques and see which technique is best suited in providing the real time data communication for VANET
