TCP over packet radio link with adaptive channel coding

A wireless packet data communications system that uses adaptive channel coding on the radio link is studied. A channel coding adaptation mechanism based on recommendation from the receiver is proposed. A traffic model that exhibits self-similarity is considered for packet data applications. The radio channel is modeled as a Rayleigh fading channel. The performance of TCP over such an adaptive radio link is obtained through analysis and simulation. The result indicates significant improvement in throughput and delay performance for TCP over adaptive packet radio link. To gain insight to dimensioning of wireless packet networks. TCP throughput and delay are studied with respect to the number of users and file size. System utilization is analyzed and theoretical bounds are derived and compared with simulation results
