Because of user mobility, highly dynamic, error-prone wireless channels, the QoS control for mobile Peer-to-Peer (MP2P) streaming media has to face considerable challenges. Given to the advantages of policy management, we develop a policy-based QoS control (PBQC) architecture to provide QoS assurance dynamically and automatically in mobile network environment. And we also propose a MP2P streaming...
Layered P2P streaming has drawn great interest in mobile cellular network in recent years. As an important technology in this application, data scheduling plays a crucial role in achieving a high Quality of Service (QoS). The Rarest-First (RF) Scheme used in Layered P2P streaming has obtained a good performance in server load and throughput of peer nodes. However, it also brings some chanllenges,...
To combat the challenges(the mismatch between throughput and layer delivery ratio, the useless packets in high layers due to the loss of packets in low layers) brought by the layered encoding to data scheduling for P2P streaming in the mobile network, We propose a new data scheduling scheme, named MLayerP2P. The key idea of the MLayerP2P is: A 3-Stage Model is used to schedule the absent streaming...
As a scalable paradigm for content distribution at Internet-wide scale, Peer-to-Peer (P2P) technologies have enabled a variety of networked services, such as distributed file-sharing and live video streaming. Most existing P2P systems employ non-intelligent peer selection algorithms for content swarming which greedily consume Internet bandwidth resources. As a result, Internet service providers (ISPs)...
Locality-based peer selection paradigms have been proposed recently based on cooperation between peer-to-peer (P2P) service providers, Internet Service Providers (ISPs) and end users in order to achieve efficient resource utilization by P2P traffic. Based on this cooperation between different stakeholders, we introduce a more advanced paradigm with adaptive peer selection that takes into account traffic...
Due to the fact that P2P applications have dominantly accounted for the entire Internet traffic, how to efficiently manage P2P traffic has become increasingly important. It has been recently proposed that the underlying network information can be shared between ISPs and P2P service providers in order to achieve efficient resource utilization, with the locality-based peer selection being a specific...
