1. IP telephony : Mobility and security
Sammanfattning : 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.

2. Autonomic wireless networking
Sammanfattning : 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. LÄS MER
3. Wireless Multi Hop Access Networks and Protocols
Sammanfattning : 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. LÄS MER
4. Contributions to IP-based wireless communications
Sammanfattning : 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). LÄS MER
5. TCP in Wireless Networks: Challenges, Optimizations and Evaluations
Sammanfattning : 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.
