Abstract:
The mismatch between current Peer-to-Peer
(P2P) overlay structures and the underlying network
topology causes high end-to-end latency and inefficient
network resource usage. This paper presents a selforganising
overlay network that closely reflects the
underlying network topology by using the basic idea of a
node locating scheme called Geographical Longest
Prefix Matching (Geo-LPM) [Il. Geo-LPM combines IP
prefixes and a network metric measurement to cluster
nodes efficiently. We optimise Geo-LPM to adapt to
different geographical locations so that nodes in the
same clusters often belong to the same physical network.
We propose to implement Geo-LPM in a distributed
fashion. As a result, the overlays utilise the underlying
network resources more efficiently and reduce the delay
from end-to-end. The system is self-organising,
distributed, and decentralised with low overhead.
