Rate Adaptation Impact on TCP Services Over Finite Buffer Size HSDPA Networks

HSDPA is an evolution of the third generation mobile network standards. This is done to achieve higher bit rates over the air links. The proposed model is used to evaluate the effect of the TCP protocol and the RNS buffer size for different rate values on the performance of HSDPA network. The performance will be assessed by means of the evaluation for both of the buffer overflow probability and the RTO blocking probability. Differently from the previous published works, a novell treatment of HSDPA performance will be done by considering the interaction between Blocking and RTO probabilities.
