Title: Towards efficient information dissemination in Peer-to-Peer networks
Abstract:
The design of efficient information dissemination systems with high expressiveness
is a challenging task. In this lecture, I will consider two systems that explore the tradeoff
between efficiency and expressiveness. First, in distributed hash table (DHT)-based P2P
networks, the proposed STAIRS framework can support the dissemination of unstructured
information. The novelty of STAIRS lies in the
low publication cost while providing users with
the full-text content subscription capability.
Secondly, the COBAS framework proposes a set
of techniques for the dissemination of
structured information, including selective
multicast by bounding intervals, cost
model-based interval division, and merging
operation. COBAS can match publication
messages with structured content against
subscription filters with a high efficiency.
Welcome!
