Data Persistence in Structured P2P Networks with Redundancy Schemes
Data service is the principle application in structured P2P networks. And in many cases, we need the data to persist for a long time. So how to persist the data service and how lo...

Cooperative Space-Time Coded Transmissions in Nakagami-m Fading Channels
— In this paper we evaluate outage performance of a cooperative transmission protocol over fading channels that requires a number of relaying nodes to employ a distributed space-...

Model based analysis for quantization parameter cascading in hierarchical video coding
Originally, the hierarchical coding structure was proposed to achieve temporal scalability. Soon after, it was realized that with a proper quantization parameter cascading (QPC) s...
