Analysis on MAC layer retransmission scheme in wireless networks

Due to poor Signal to Noise and Interference Ratio (SNIR) in wireless networks, retransmission schemes are proposed to improve the transmission performance. These retransmission schemes can be classified into three levels-frame level, block level and bit level according to their retransmission granularity. Analysis on these schemes is significant for applying suitable retransmission scheme, evaluating transmission performance, optimizing retransmission schemes or protocols, etc. In this paper, we modified the implementation of retransmission strategy algorithm used in PPR because our algorithm is more computation efficient and more easy to analysis. And according to the metric FDDR we introduced, we analyze the retransmission performance of three level retransmission schemes. For performance analysis of different levels, we use 802.11, Seda and PPR as typical schemes, respectively. We obtain the optimal frame size and the best FDDR of theses schemes and discuss their changes in different Bit Error Rate (BER) scenarios.
