Analytical TCP Throughput Model for HSDPA∗

چکیده
In this paper, an approximate, Padhye model based TCP throughput calculation method is presented for mobile data services over HSDPA. The Padhye model is defining the TCP throughput based on two input parameters: the packet loss probability and the TCP Round Trip Time. In order to provide the input parameters for the TCP throughput calculation, an equivalent queuing network model of the HSDPA system is created, which includes the congestion points and protocol layers that are having dominant impact on the delay and packet drop. The solution of the queuing network model is described in detail. Finally, the model is validated with NS2 simulations.

Performance evaluation of TCP over HSDPA based on measurements
HSDPA technology has been recently introduced by UMTS mobile operators as a solution both for increasing the downlink throughput and for achieving a more efficient usage of the radio resources. This work analyses the performance of TCP traffic over HSDPA from the user perspective based on experiments and measurements over a real network. The effect of multiple HSDPA users sharing the overall ca...

This paper investigates the performance of TCP over High Speed Downlink Packet Access (HSDPA) link in the third generation Universal Mobile Telecommunication System (UMTS). The throughput performance of TCP has been considered with both round robin and maximum carrier-tointerference scheduling schemes. A simulation based approach is adopted to determine the total cell throughput, both under ide...

متن کاملJoint uplink and downlink admission control to both streaming and elastic flows in CDMA/HSDPA systems
TCP-based data flows generate packets and ACKs in two directions, be it in the wireline or wireless networks. In the latter case, packets are typically found in the downlink whereas ACKs are in the uplink. Those two links are asymmetric in the case of CDMA-based High Data Rate (HDR)/High-Speed Downlink Packet Access (HSDPA) systems, the uplink being much slower than the downlink and thus, in so...

Nowadays, there are lots of demands by Internet applications (e.g. IP based multimedia applications). For higher data rate, there exist two technologies: the third generation (3G) cellular mobile networks and the wireless local area networks (WLAN) technology have big distinctions, which can meet different users’ demands of accessing the Internet. For the 3G cellular networks technology, one of...
