摘要
En 中文
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.
