CESG Seminar: Random Hamiltonian Cycles and Real-Time Streaming in Peer-to-Peer Networks

October 26, 2012 @ 3:00 pm - 4:00 pm

Room 1037 Emerging Technologies Building (ETB)

We are motivated by the problem of designing simple distributed
algorithms for peer-to-peer streaming applications that can achieve
high throughput and low delay, while maintaining a very small neighbor
set for each peer. Our algorithm constructs multiple random directed
Hamilton cycles and disseminates content over the superposed graph of
the cycles. We show that the algorithm achieves any arbitrary fraction
of the maximum streaming capacity while maintaining a small streaming
delay. The result is established by showing that the superposed graph
is an expander with high probability.
