Location:    Room 1C-502, SIST Building

In this talk, I will introduce a peer-to-peer (P2P) system based on harvesting data in a community utilising multi-hop device-to-device (D2D) communications. The P2P system optimises D2D communications for P2P local file sharing, improves user experience, and offloads traffic from the base stations (BSs). The P2P system features cross-layer integration of: 1) a wireless P2P protocol based on the Bittorrent protocol in the application layer; 2) a simple centralised routing mechanism for multi-hop D2D communications; 3) an interference cancellation technique for conventional cellular (CC) uplink communications; and 4) a radio resource management scheme to mitigate the interference between CC and D2D communications that share the cellular uplink radio resources while maximising the throughput of D2D communications. Simulation results show that the D2D enabled P2P system can increase the cellular spectral efficiency, reduce the traffic load of BSs, and improve the data rate and energy saving for mobile users.
