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...

Collaborative Event-Driven Coverage and Rate Allocation for Event Miss-Ratio Assurances in Wireless Sensor Networks
Wireless sensor networks are often required to provide event miss-ratio assurance for a given event type. To meet such assurances along with minimum energy consumption, this paper ...

Multiple-Description Speech Coding Using Speech-Polarity Decomposition
We present and evaluate a new multiple-description coding extension to the international standard for pulse code modulation speech coding (ITU-T Rec. G.711). This extension is inse...

Scalable video compression using longer motion compensated temporal filters
Three-dimensional (3-D) subband/wavelet coding using a motion compensated temporal filter (MCTF) is emerging as a very effective structure for highly scalable video coding. Most p...
