A wireless ad hoc network is a complex dynamical system composed of a large number of simple systems interacting through a communication medium. Such systems arise as natural models in many areas of engineering and sciences apart from wireless networks, such as autonomous unmanned vehicles, biological networks, and animal cooperative aggregation and flocking phenomena. My main focus is on optimal distributed power control, contention control, scheduling and cross-layer optimization.

This projects aims towards a theoretical framework for analysis of consensus algorithms for multi-agent networked systems. Our work is based on tools mainly from matrix theory, algebraic graph theory and control theory. We discuss the connections between consensus problems in networked dynamic systems and diverse applications including power grids, ReduceMap and distributed resource allocation in cloud computing (in collaboration with Prof Christoforos N. Hadjicostis).

Lossless fixed to variable length source codes are usually examined under known source probability distributions, and unknown source probability distributions. For known source probability distributions there is an extensive literature which aims at minimizing various pay-offs such as the average codeword length, the average redundancy of the codeword length, the average of an exponential function of the codeword length, the average of an exponential function of the redundancy of the codeword length. On the other hand, universal coding and universal modeling, and the so-called Minimum Description Length (MDL) principle are often examined via minimax techniques, when the source probability distribution is unknown, but belongs to a pre-specified class of source distributions (in collaboration with Prof Charalambos D. Charalambous).

Cooperative transmission has received a lot of attention because it can enhance the reliability of data transmission, provide broader and low-cost coverage and combat shadowing and fading effects. For cooperative networks with multiple relay nodes that can assist the source transmission through either multi-hop relaying or cooperative diversity, relay selection has been introduced as an efficient technique.

Resource management in virtualized data centres is important and challenging, particularly when dealing with complex multi-tier server applications and fluctuating workloads. Our aim is the development of control methods for resource provisioning of server applications in virtualized data centers (in collaboration with Dr Evangelia Kalyvianaki).

My fourth year project concerned "Ways of interacting with Virtual Environments" and was implemented under the supervision of Dr Joan Lasenby. The work done can be distinguished into two parts: The first one involves hand-eye coordination with the aid of a virtual environment and the second one considers skeleton formation with the aid of LED markers.
