Abstract
Vehicular Ad-Hoc Network (VANET) has gained the interest of the researchers in the current decade. VANET can be implemented to improve safety of vehicles on road and offer greater comfort to the drivers and passengers in traffic. Due to high mobility of vehicles frequent handoffs are required in VANET. These frequent handoffs must be carried out in an efficient manner with reduced handoff latency. To reduce the handoff latency during a switch, the scanning time to search for the new access point must be reduced significantly. Various schemes have been proposed which perform a pre-scanning in order to reduce handoff delay. This paper presents a survey of such pre-scanning schemes and tries to explore new areas of enhancements which will result in decrease of handoff latency. A qualitative comparison of these schemes is also carried out which leads to newer areas of research, where significant improvement can be beneficial.
