Multiple Multicast Trees for 3D Real-Time Content Distribution over P2P Networks

Current developments in 3D technology have triggered an increasing user interest in experiencing this technology however the distribution of 3D media to a large amount of users raises significant technical challenges mainly due to bandwidth and delay restrictions associated with the multiple views of content. In this paper, we discuss a hypothetical distribution scenario that uses multiple multicast trees over peer-to-peer networks for 3D real-time content distribution and present a new algorithm for the creation of multiple multicast trees. Furthermore, this paper also proposes a mechanism to deal with peer failures, based on offline computation of backup trees and selective updates upon peer failure. The algorithm is evaluated through simulation results obtained by our own developed Java simulator.
