Bit Error Rate Analysis of Partial Packets in Ad Hoc Wireless Networks

Abstract

An ad hoc wireless network environment is constructed and the number of errors in partial packets, bit error time series, is collected to study bit error rate of wireless burst-error channels. It is verified that the bit error time series is chaotic by computing maximal lyapunov exponent. The self-similarity of the bit error time series is also validated using the rescaled range (R/S) method, the aggregated variance time (V/T) method, absolute moment method and periodic diagram method respectively. Our research results show that we can utilize the complex non-linearity system theory such as chaos and self-similarity to study the number of errors in a partial packet. It is very important for evaluating bit error rate of wireless burst-error channels and prediction of the bit error ratio of a partial packet in ad hoc wireless network.
