I am a Research Fellow at Q2S, Department of Telematics, NTNU, Norway.
The rapid growth of delay sensitive applications, such as VOIP and IP video, and the scarcity of the radio spectrum require the design of spectrally-efficient systems with quality of service (QoS) support such as provisioning of delay guarantees. Furthermore, in communication networks, source burstiness is the central phenomenon that underlies the process of resource sharing for communication. Multiple input multiple output (MIMO) and code-division multiple-access (CDMA) systems are few examples of spectrally-efficient systems. The traffic carrying capacity of such systems without QoS support is a well studied area using tools from information theory and the focus has therefore been primarily at the physical layer. The traffic carrying capacity of these systems with bursty sources and under QoS constraints is, however, less well-understood.
Delay and burstiness are inherently link layer parameters. This calls for a cross layer approach in which the physical layer parameters such as signal to noise ratio, fading, receiver structure and the link layer QOS parameters such as delay and burstiness can be modeled together. To this end, the aim of my PhD is to predict the traffic carrying capacity of communication networks under delay and burstiness constraints.
