BitTorrent file sharing using Tor-like hidden services

The Internet is a large public network of networks and computers. When no countermeasures are taken, all information and activities taking place on the public Internet are subject to traffic analysis, threatening personal freedom and privacy. The first measure to take is securing all transferred information by applying encryption on it, which...

Robust Communication Framework for Unmanned Aerial Systems

Unmanned Aerial Systems (UASs) are emerging in the industrial, consumer and re- search domains. A key challenge for UAS communications is overcoming slow and unreliable wireless connectivity by achieving high link utilization on multiple radio interfaces. We have developed and implemented a peer-to-peer communication framework, based on Dispersy...

Closing the gap between the Web and Peer to Peer

During the course of Q4 of the 2012-2013 academic year, we have worked on the project of a Peer-to-Peer web browser. After a two week orientation phase, a six week programming phase and nally another two week reporting phase we deliver our product. The final result of this endeavor is an integrated web browser in the Tribler platform, which...

Libswift-PPSPP Information Centric Router: SHA1 Accelerator

Peer to peer content streaming is the next generation content delivery method, making obsolete the client-server communication model which is not sustainable in the current Internet environment. One effort to standardize this new protocol is represented by the Libswift-PPSPP (Peer to Peer Streaming Peer Protocol) Information Centric Network (ICN...

Offline Trace Synchronization for Smartphone Energy Profiling

Energy profiling is a means to effectively understand the power behavior of smartphone applications. However, no tool that effectively combines portability, accuracy and automation has been proposed yet. In this thesis a new approach is proposed, which sets the basis for such a tool by solving a trace synchronization problem. TRAce Merger uses...

Merging the best of HTTP and P2P

The World Wide Web is growing fast. Web content is growing as well. To cope with this trend, server infrastructures must be able to serve a huge amount of traffic. When this cannot happen, service denial is the consequence. Small content publishers are the most affected by this phenomenon. At the same time, BitTorrent is leading the file sharing...

Splash: Data synchronization in unmanaged, untrusted peer-to-peer networks

Peer-to-peer networks rely on gossip algorithms to spread information about the peer activity and the network status. State-of-the-art gossip algorithms are not sufficient to spread the information widely, as the size and the complexity of the unmanaged networks grow. They suffer from high bandwidth utilization and lack mechanisms to verify the...

CoopViz: Real Time Visualization of BitTorrent Swarm Dynamics

Multi Bit-Rate Video on Demand for P2P networks

The Internet has become in the last years more and more a means of conveyance for multimedia delivering. Many solutions have been proposed to gain high quality of service for video on demand in client-server environments, with adaptive algorithms that adjust the bit-rate of a video stream depending on the clients available bandwidth. Providing...

Reducing Free Riding in Peer-to-Peer Systems with Supervised Teaming

Peer-to-peer technology has produced thriving communities in which peers contribute bandwidth to each other. However, when free riding occurs, these communities will not be able to sustain themselves without incentives to enforce this contribution. This thesis presents Supervised Teaming, a peer-to-peer transfer protocol that gives uploading...
