Article
Duty cycling mechanism has been widely used to conserve energy that consumed by idle listening in wireless sensor networks, while fixed duty cycling introduces transmission latency in packet delivery. End to end latency is one of the most significant factors of packets loss in wireless sensor nodes, and many techniques have been proposed based on l...
Article
Manifold learning and Sparse Representation Classifier are two popular techniques for face recognition. Because manifold learning can find low-dimensional representations for high-dimensional data, it is widely applied in computer vision and pattern recognition. Most of the manifold learning algorithms can be unified in the graph embedding framewor...

The design of routing protocols for Underwater Acoustic Sensor Networks (UASNs) poses many challenges due to long propagation, high mobility, limited bandwidth, multi-path and Doppler effect. Because of the void-hole caused by the uneven distribution of nodes and sparse deployment, the selection of next hop forwarding nodes only based on the state...
Conference Paper
In opportunistic networks, due to the limited resources such as energy, buffer and wireless bandwidth, nodes will be selfish and unwilling to forward messages for others, which will seriously degrade the routing performance. Therefore, it is necessary to design an effective incentive scheme to motivate the selfish nodes to cooperatively forward mes...
Article
Underwater acoustic sensor network (UASN) is a promising technique, which will facilitate a wide range of aquatic applications. However, because of adverse underwater environments, UASN faces grand challenges and problems such as limited bandwidth, node movement, long propagation delay, three-dimension deployment, energy-constraint, expensive manuf...
Article
Designing an efficient routing protocol for underwater acoustic sensor networks is a great chanllenge because of the adverse enviroment factors, such as long propagation, high code error rate, high mobility and limited bandwidth. Many routing protocols have been presented for underwater sensor networks, but most of them only consider one-hop forwar...
Conference Paper
To improve the situation of insufficient global research in K-Means Algorithm, this paper discusses an optimized K-Means clustering algorithm based on artificial fish swarm, which overcomes the sensitivity to initial clustering center selection of K-Means clustering algorithm and gets the optimal global clustering partition. Meanwhile, to improve t...
