  2. 1. IP telephony : Mobility and security

    Author : Jon-Olov Vatn; Björn Pehrson; William Arbaugh; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Telekommunikation; Telecommunication; Telekommunikation;

    Abstract : With the introduction of IP based telephony services, the Internet has started to challenge the traditional PSTN networks as an infrastructure for providing real-time interactive services. This upcoming paradigm shift is not only driven by the desire to provide cost efficient solutions, but by basing the communication on IP we expect that the end-users will experience a greater set of attractive services over a single connection compared to what is provided by a PSTN today.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; wireless LAN; autonomic communications; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Large-scale deployment of IEEE 802.11 wireless LANs (WLANs) remains a significant challenge. Many access points (APs) must be deployed and interconnected without a-priori knowledge of the demand. We consider that the deployment should be iterative, as follows. READ MORE

  5. 3. Wireless Multi Hop Access Networks and Protocols

    Author : Anders Nilsson Plymoth; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi Hop Access; Wireless Networks; Mobile IP; Performance Evaluation; Medium Access Control; Routing; Wireless Ad hoc Networks;

    Abstract : As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. READ MORE

  6. 4. Contributions to IP-based wireless communications

    Author : Héctor Luis Velayos Munoz; KTH; []
    Keywords : ;

    Abstract : The introduction of IP-based communications in wirelesssystems posed several research issues. In this thesis, wepresent different contributions to address some of the issuesin terminals and radio access networks. Firstly, we look atapplication adaptation to varying levels in quality of service(QoS). READ MORE

  7. 5. TCP in Wireless Networks: Challenges, Optimizations and Evaluations

    Author : Stefan Alfredsson; Anna Brunström; Lars-Åke Larzon; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless networks; TCP IP; TCP-L; Network emulation; Computer science; Datavetenskap; Computer Science; Datavetenskap;

    Abstract : This thesis presents research on transport layer behavior in wireless networks. As the Internet is expanding its reach to include mobile devices, it has become apparent that some of the original design assumptions for the dominant transport protocol, TCP, are approaching their limits.
