Simulation for Analysis of Wireless Can for Time Response

Expanding Response Time Analysis for Wireless CAN Communication

Abstract

This paper attempts to model and simulate wireless CAN (WCAN) for both constant bit rate (CBR) and variable bit rate (CBR) traffic (VBR). While researchers have presented different ideas on wireless CAN modelling, due to its noted benefits, WCAN is implemented in this study using the token frame scheme. In this work, WCAN simulation done using QualNet, an algorithm is built based on this WCAN using a token scheme. For both constant bit rate traffic (CBR) and variable bit rate traffic (VBR) used for performance measurement, this paper outlines the modelling of wireless CAN (WCAN) using token scheme, the process adopted for simulation using QualNet, and the estimation of parameters such as throughput, end-to-end delay and packet transmission ratio. As response time analysis is more important for safety-critical applications than performance analysis, it is considered appropriate to expand the analysis and to obtain the response times of both frequent and intermittent WCAN communications. Also presented here are the findings of several simple QualNet tests for both WCAN and IEEE 802.11b.
