This paper advocates a Virtual Vision paradigm and demonstrates its usefulness in camera sensor network research. Virtual vision prescribes the use of a visually and behaviorally ...
Abstract— A least-squares (LS) channel estimation (CE) technique for mobile OFDM communications over a rapidly timevarying frequency-selective fading channel is investigated in t...
Abstract— To construct an efficient overlay network, the information of underlay is important. However, the inference of an underlay topology is not easy. We consider using end-...
Application-layer overlay networks have recently emerged as a promising solution for live media multicast on the Internet. A tree is probably the most natural structure for a mult...
Clustering in Mobile Ad Hoc Networks (MANETs) has shown to be a promising technique to ensure the scalability and efficiency of various communication protocols. Since stations in...
