The link of wireless sensor networks used in home automation may be instable due to the effects of shadow fading. Designing a suitable routing algorithm to improve the packet delivery ratio and reduce the delay in shadow fading environment is strongly required, and therefore the Link-State-Aware Routing for Wireless Sensor Network in Home Automation (LSAR-WSNHA) algorithm is proposed. However, when...
Interest point detection is one of the key technologies in image processing and target recognition. This paper presents a new method for detecting interest points in digital images and computer vision problems based on complex network theory. We associate a directed and weighted complex network model to each image and then we propose three different algorithms to locate these key points based on three...
This article covers a problem that often arises in real life situations-the maximum flow problem. This problem is a classical combinatorial optimization problem, which arises in many engineering and scientific applications. It is also the important content of computer science and operational research. In order to reduce computational complexity, many improvement methods have been proposed. In this...
With regard to large-scale network, the classical methods are not suitable for resolving the problems of network analysis, which is due to large space demanding and time consuming. Most of large-scale networks have the feature of community structure in the area of complex network. Sub graphs of the original network have closer relations within them while estranged one between any two sub graphs. Therefore,...
