Consensus algorithm is widely used for Cooperative Spectrum Sensing (CSS) in Cognitive Radio Networks (CRNs). However, using this method, much of time and energy consumption for cooperation is wasted by repeatedly recirculating redundant information. We propose a novel Contextual Binary Gossip (CBG) algorithm for CSS. Utilizing the contextual information, two Secondary Users (SUs) will exchange sensing...
Clustering is a good method to increase WSN lifetime and particularly for smart environment. In this paper, we present fuzzy position based routing for clustered sensor network. It is very useful for the smart environment applications of wireless sensor network without GPS support. The destinations could be located with ambiguous position vectors, and the long time and energy consumption of requesting/replying...
Recently, the notions of compressed sensing (CS) have attracted attention as an innovative concept in signal processing. In this exploratory paper, a CS-based video compression approach suitable for wireless capsule endoscopy is proposed. In general, the amount of video data generated by capsule endoscopy is so large that video compression is the best way to lower the communication bandwidth and save...
An inherent concern for a wireless sensor network (WSN) is the unbalanced energy consumption problem, where sensors closer to the sink are more likely to exhaust their energy faster than other nodes. To mitigate this problem, this paper considers including some resource-rich mobile nodes, called mobile data-pumps, to conduct data relaying from static sensors to the sink. The network thus becomes a...
