Logical link control techniques for wireless ATM network
Xiao Feng, Y. Li, Guoan Bi · IEE Proceedings - Communications · 1999
In wireless ATM networks, a logical link control (LLC) layer is necessary to mitigate the effect of errors caused by the radio channel before cells are released to the ATM network layer. The authors propose and evaluate some LLC techniques, compare the system performance for different packet lengths, and discuss the trade-off between complexity and performance. The lengths of the used packets in different conditions are suggested. Simulations for conventional ARQ and code combining ARQ in a Rayleigh fading environment are carried out, and the results indicate that code combining ARQ is a simple and efficient technique.
