Abstract :
This paper provides optimum packet size that maximize the throughput efficiency of TCP/IP traffic as a function of data packet length for several values of channel BER over wireless ATM links applying data link error control schemes to reduce error problems encountered in using wireless links. For TCP/IP nondelay-sensitive traffic requiring reliable delivery, it is necessary to adopt data link layer ARQ protocol. ARQ error control schemes considered include GBN ARQ, SR ARQ and type-I hybrid ARQ, which ARQ is needed, but FEC can be used to reduce the number of retransmissions. Especially, Adaptive type-I hybrid ARQ scheme is analyzed for a variable channel condition to make the physical layer as SONET-like as possible.
