This paper presents an efficient ARQ protocol, called WO-RANC, to enhance coverage and performance of IEEE 802.11p. WO-RANC exploits relay-assisted network coding and work-based wide-sense opportunistic retransmission. Relay nodes with strong connectivity to destinations opportunistically deliver information to the destinations on behalf of sources, thus(More)
In this paper, we address the problem of detecting and segmenting partial image blur from a single input image. Instead of assuming particular image priors or requiring additional user annotation, we propose a novel learning framework which jointly solves the tasks of blur kernel estimation and image blur segmentation, so that partial image blur can be(More)
For lifetime extension, energy-efficient mediumaccess control (MAC) protocols designed for battery-powered wireless sensor networks (WSNs) usually enable nodes to operate in low duty cycle. However, without offline change in system parameters, existing protocols either save energy at a cost of long latency or work well only for a narrow range of traffic(More)
