With the development of science, remote data visualization is playing an increasingly important role. Meanwhile working on the road is becoming the life style of modern society. However, handicapped by the limits of the mobile embedded device and mass data to be visualized, the remote data visualization for mobile clients is still a big challenge. In this paper, we enhance our previously developed...
Location information is of paramount importance for wireless Sensor Networks (WSNs). The design of WSNs has always been focused on an specific point of networks in a two-dimensional (2D) space. Nowadays this design is not enough and the study of the three dimension is needed. In this article, we focus on 3D location accuracy in WSNs. We quantify the estimation accuracy for the RSS measurements by...
A fuzzy multi-objective integer programming model is developed in this paper for solving the logistics service selection problem with multiple objectives, in which some of the parameters are fuzzy in nature. And an asymmetric fuzzy-decision making technique is applied to enable the decision-maker to assign different weights to various criteria. An application example was also given to testify the...
