Optimization of Vehicular Ad Hoc Network using Taguchi method

Vehicular Ad Hoc Network (VANET) is quite different from other ad hoc networks in term of functionality because of the variable node density, high node mobility, and unpredictable and harsh communication environment. There are two major applications VANET, namely safety applications and non-safety applications. In addition, network optimization is one way to maintain the existing protocols and other network parameter compare to design and implementing new improved protocols in which it too costly. Motivated with the reasons this paper presents an optimization of vehicular network for throughput, end-to-end delay and packet delivery ratio using Taguchi method. Highway scenario is chosen as the evaluation condition for this paper. For three performances evaluated, the highest rank value shows the different factors. For safety application which is delay-sensitive, routing protocols is the highest rank control factors. Non-safety application which is throughput sensitive, packet size is the main control factors.
