Peer-to-peer (P2P) systems have emerged as a potential technology to
build very-large distributed data and resource sharing systems.
A key problem in these systems is the location of resources.
Most approaches, address the scale challenge using either structured
(DHTs) or unstructured overlay networks. Unfortunately, these solutions
have a tradeoff between efficiency and flexibility. DHTs are more
efficient but are specialized to address exact-match queries,
whereas unstructured solutions, that typically rely in some sort of
blind search mechanism, incur in additional overhead, but can address
arbitrary complex queries. This thesis makes a survey of the main strategies
to implement resource location in P2P systems, identifies some possible lines
of research to improve the current state of the art and presents a novel
self-organizing architecture to perform resource location.
This architecure combines structured and unstructured approaches to support
flexible and efficient resource location. For instance, the architecture
can be used to perform distributed resource allocation in cloud
Experimental results extracted through simulation validate this
design, and show that the proposed solution is able to offer a
good recall, with small overhead and low latency.
