Implementation of MIMO and AMC Techniques in WiMAX Network based VANET System

Abstract

Vehicular Ad-hoc Networks (VANETs) are expected to implement wireless technologies such as Dedicated Short Range Communications (DSRC) which is a category of Wi-Fi. Other candidates of long distance wireless technologies are cellular, satellite, and WiMAX. VANETs can be viewed as component of the Intelligent Transportation Systems (ITS). This paper presents the implementation of Multiple Inputs Multiple Outputs (MIMO) and Adaptive Modulation and Coding (AMC) techniques in WiMAX based Vehicular Ad-hoc Network. This designed system provides multiple radio channels in between transmitter and receiver for transmission and reception of the data by using the concept of MIMO technology. Also AMC provides the selection of different modulation techniques depending on the signal to noise ratio of the channel. These two techniques provide the significant change in the throughput, delay, jitter, and packet delivery ratio and packet loss ratio than existing vehicular ad-hoc network. WiMAX based VANET provides high speed, low cost per bit and large coverage area.
