As a typical routing algorithm of hierarchy for wireless sensor networks (WSNs), LEACH is a good solution for energy efficiency. However, LEACH still has some disadvantages, such as unreasonable structure of clustering, direct communication between all clusterheads and sink node, which brings high energy consumption. An improved routing algorithm based on LEACH, known as ILEACH, is proposed in this...
As community detection having been a hot issue in recent years, firstly the correlate clustering technologies based on local information are studied and summarized. Secondly, the label propagation algorithm that is short for LPA is researched and analyzed in depth. Finally, for the random strategy of LPA results that the network partition is always not optimal, we introduces the concept of the similarity...
Clustering of entity pairs is the core content of the unsupervised relation extraction method. However, most of the clustering algorithm in the previous unsupervised relation extraction does not take into account the influence of the duality between entity pairs and the relationship characteristics on clustering results. In order to overcome this defect, this paper proposed a novel clustering algorithm...
At present, the textile image is separated by manpower with low efficiency. In order to deal with this problem, this paper proposes a novel algorithm for textile image separation based on back propagation artificial neural network. The factors that can affect the result of image separation are the RGB values of a pixel itself, the color of its adjacent pixels, and its boundary probability. According...
Wireless sensor networks (WSNs) consist of a large number of nodes with limited battery power. Thus, the communication must be designed to conserve the limited energy resources of the nodes. In this paper, we propose a cluster-based multipath delivery scheme, called CMDS, which uses cluster and multipath to improve the capability of load balance, and thus prolonging the network lifetime. Firstly,...
