Abstract
The present day automotives have variety of attractive features. Incorporating these features is possible with more electronics or embedded systems inside the vehicle. Controller Area Network (CAN) protocol offers low cost solution for communication between these embedded systems. These embedded systems communicate on CAN bus via message passing. With limited speed and bandwidth offered by CAN, there are limitations in communication. One of the solutions to overcome these limitations is the use of Data-Reduction (DR) algorithms or techniques. These algorithms make it possible to send fewer amount of data in the given time, thus reducing the bandwidth per message. This paper develops an alternative approach to data reduction technique called Quotient Remainder Compression (QRC) algorithm. It provides double or at least equal range to the variation in the parameter as compared to the Enhanced Data Reduction (EDR) algorithm. The compression ratio of QRC is comparable to the earlier algorithms.
