Abstract :
One critical issue in wireless systems is the efficient encoding of data in the presence of noise and Rayleigh fading. We analyze automatic repeat request (ARQ)-selective repeat and forward error correction control (FEC) algorithms using Markov chain model for mobile systems that can optimize the amount of battery energy consumed by transmitters. In this paper, we introduce an enhanced distributed algorithm which dynamically balances the combination of FEC and ARQ. The algorithm is shown to be suitable for both real time and non-real time multimedia environments. Extensive simulation indicates that our proposed algorithm outperforms existing schemes solely based on either FEC or ARQ and demonstrates the usefulness of our novel scheme
