Experimental analysis of TCP behaviour over a downlink UMTS channel under different scheduling strategies
نویسندگان
چکیده
Cellular systems, such as UMTS, use scheduling algorithms in order to provide fair sharing of the available bandwidth among the different users. However, the use of scheduling algorithms in wireless networks can have a great impact on the performance of TCP based applications. The objective of the paper is the identification of the effects observed in legacy TCP connections over a UMTS downlink shared channel (DSCH) under two different sets of scheduling strategies: rate and timeout oriented. To perform the analysis a real time UMTS emulator has been used.

One of TCP's key tasks is to react and avoid network congestion episodes which normally arise in packet switched networks. A wide literature is available concerning the behaviour of congestion control algorithms in many di erent scenarios and several congestion control algorithms have been proposed in order to improve performances in speci c scenarios. In this paper we focus on the UMTS wireles...
متن کاملSimulation-Based Performance Analysis of HSDPA for UMTS Networks
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 کاملPerformance Evaluation of TCP Variants over UMTS Networks
With the evolution of 3G technologies like Universal Mobile Telecommunication System (UMTS), the usage of TCP has become more popular for a reliable end-to-end (e2e) data delivery. However, TCP was initially designed for wired networks and therefore it suffers performance degradation due to the radio signal getting affected by fading, shadowing and interference. There are many strategies propos...
