Distributed Hash Tables (DHTs) have emerged as the most popular scheme in the P2P network, which have drastically changed the way we share resources and gather information. In order to solve the problem of search flexibility In DHT, an improved lookup and routing protocol based on Content Addressable Networks (CANs) is proposed, which not only preserves CANs' simplicity, but also achieves a resilient...
As a superior approach for peer-to-peer (P2P) streaming live media, mesh-based overlay has made much success due to its potential scalability and ease of deployment. Peers in mesh streaming systems employ a swarming content delivery mechanism to exchange resources. However, the limited availability of new content heavily affects the quality of delivered stream. Aiming at leveraging and optimizing...
The current peer-to-peer (P2P) live streaming networks can be generally classified into two categories: tree-based and data-driven. The tree-based approach suffers from three limitations: interruptive delivery due to failures of high level nodes, unfair uploading (out-going) bandwidth utilization in leaf nodes and bandwidth bottleneck in nodes near the root. The data driven approach has been widely...
In a structured peer-to-peer (P2P) overlay network, the stability of the entire network will be greatly affected by simultaneous join-in and drop-out of large amount of nodes. Aiming at reducing the overhead of handling this activity, we propose a group-based hierarchically structured overlay network, GSON. GSON is also a structured P2P overlay network using distributed hash table (DHT). In GSON,...
