The idea:
Distributed systems are computing platforms built from networked components. The Computing Systems Lab has a long history in the field, especially in the area of cluster computing, where the goal is to exploit as much processing power as possible from multiple computing nodes connected via low-latency links. With the Internet boom, distributed systems can also be formed by common, personal computers, located all over the world. In this collaborative environment all nodes assist each other in order to implement a single service. You may be familiar with the term peer-to-peer, where all participating elements of the overall distributed system have equal responsibilities. My research is about peer-to-peer systems and how they can be tailored to a wider range of distributed applications. Make sure you also visit the home page of my advisor, Asst. Prof. Nectarios Koziris.
