Performance Analysis of 802.11 and 802.11p in Cluster Based Simple Highway Model

Vehicular Adhoc Network (VANET) is a special type of Intelligent Transport System (ITS), where the mobile nodes are cars, two wheelers, trucks, buses etc., that move on well organized and predefined roads in both direction at very high speed. Following traffic rules, the vehicles provide communication with each other directly (Inter Vehicle Communication IVC) or indirectly through the Road Side Unit (RSU). Usually vehicles, which move outside the city area, do not get the response from the Road Side Unit, as its availability is limited in that area. For this purpose an attempt has been made to create a new clustering concept, which can be applied to the newly created Simple High Way Mobility Model, to increase the speed of the vehicle communication. Thus this paper focuses the performance of Packet Delivery Time, Packet Delay Time, Throughput, Normalized routing load, Broad casting time using IEEE 802.11p. This is compared with the values obtained for IEEE802.11 in VANET Environment.
