Error Control System for Parallel Multichannel Using Selective Repeat ARQ

In Wireless Parallel Multichannel data communication system using Selective Repeat Automatic Repeat Request protocol for Error Control Transmission. We assume the modified scheme for improve the performance of Data Transmission over Selective Repeat ARQ by adding SW ARQ protocol features. We evaluate the resequencing delay and the resequencing buffer occupancy, respectively. Under the assumption that all channels have the same transmission rate but possibly different time-invariant error rates, we derive the probability generating function of the resequencing buffer occupancy and the probability mass function of the resequencing delay. Then, by assuming the Markov error model for each channel, we extend our analysis to time-varying channels.
