  1. 1. Performance Evaluation of TCP Variants over UMTS Networks

    University essay from Institutionen för informationsteknologi

    Author : Nikunj Modi; [2008]
    Keywords : ;

    Abstract : With the evolution of 3G technologies like Universal Mobile TelecommunicationSystem (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. READ MORE

  3. 2. Overhead Impacts on Long-Term Evolution Radio Networks

    University essay from KTH/Kommunikationssystem, CoS

    Author : Petter Edström; [2007]
    Keywords : Long-Term Evolution; LTE; Power Emission; Efficiency;

    Abstract : As a result of the constant efforts to improve mobile system performance and spectral efficiency, the 3GPP standardization forum is currently defining new architectural and functional requirements that hope to ensure long-term evolution (specifically defined as the “Long-Term Evolution (LTE) concept”) and general future competitiveness of the 2G and 3G radio access technologies. Previous discussions on LTE efficiency have been focused on general assumptions on signaling overhead and overall system capacity, based on experience from existing mobile systems. READ MORE

  4. 3. Simulation analysis of RLC/MAC for UMTS in Network Simulator version 2

    University essay from Institutionen för systemteknik

    Author : Anders Björsson; [2004]
    Keywords : Reglerteknik; network; simulation; 3G; UMTS; MAC; RLC; Reglerteknik;

    Abstract : The Internet has mainly been interconnecting stationary computers by wired links, but an increasing number of mobile clients require wireless communication. One way to connect these clients is to use the Universal Mobile Telecommunication System, UMTS. UMTS is a third generation mobile system. READ MORE

  5. 4. TCP performance in an EGPRS system

    University essay from Institutionen för systemteknik

    Author : Klas Adolfsson; [2003]
    Keywords : TCP Transmission Control Protocol ; TCP IP; EGPRS; GPRS; EDGE; GSM; wireless; RLC MAC; Temporary Block Flow; TBF;

    Abstract : The most widely used protocol for providing reliable service and congestion control in the Internet is the Transmission Control Protocol (TCP). When the Internet is moving towards more use in mobile applications it is getting more important to know how TCP works for this purpose. READ MORE
