Abstract :
Link layer error control is one of the important technologies in mobile systems. In this paper, adaptive error control investigated using a modified Markov decision process (MDP) model is discussed. An adaptive error control strategy, where the MAC frame length adapts to the varying channel condition, was developed. The proposed algorithm implemented online, achieves better average link layer throughput in a dynamic data channel. The simulation example provided shows that the algorithm can improve the throughput of the wireless data channel by 23%
