To increase classification accuracy of college students' mobile learning (m-learning) strategies in foreign language learning, a classification model based on principal component analysis (PCA) and probabilistic neural network (PNN) is proposed. First, an index system of college student m-learning strategy evaluation was established. Second, PCA was employed to reduce the dimensions of the original...
Modern cellular resource management for dynamic control of channel resources and energy efficiency improvement relies largely on early and accurate monitoring and prediction of cellular base station traffic volumes. Analysis of network traffic volume over space and time plays an important role in traffic prediction. In this paper, we examine both the temporal and spatial characteristics of cellular...
In this paper, we consider a mobile advertising recommendation system using item-based Top-N recommendation algorithm based on Hadoop framework and then propose a solution based on the Hadoop framework to build a distributed recommendation system. We also introduce advertising server into the system. Seller will pay for their advertising when it is clicked by users, so that this platform can make...
Intelligence has become more and more popular, especially in smart grid. Nowadays, the inspection for power elements has changed from a traditional method to a more intelligent way using mobile terminals, which has greatly improved the work efficiency. However, this new method may reveal individual privacy such as workplace, work hours and personal habits, which may become background knowledge for...
In this paper, the forwarding objective and the mobility law of nodes in opportunistic networks are investigated to establish a mathematical model for further analysis, and then a new data forwarding algorithm is proposed. In this algorithm, according to the distance between the data holders and the destination, some intermediate nodes are selected to relay the data. Especially, the forwarding copies...
This paper develops a modulated platform for the resource management of wireless public network to offer monthly analysis and comparison of data communication cards. The platform is consisted of three modules, namely the management module for public communication resource, operator bill module and distribution and measurement automation module. Compared with the conventional management platform, the...
In this work, by using random access and priority considerations we develop a mobile healthcare network. We assign 4 medical information priorities to the nodes of wireless body area network. Accurate and quick prioritization of personal healthcare information is crucial for making efficient and real-time decisions. We transfer the medical data to the access point in wireless body area network by...
NAT (Network Address Translation) traversal is one of the main obstacles to restrict the development of SIP (Session Initiation Protocol). This paper analyzes problems about SIP/NAT traversal and proposes a scheme for SIP operating through NAT with the cooperation of SIP server and RTP relay server and designs the architecture of the relay server according to the characteristics of the mobile Internet...
It is a general practice that using two vehicles to transport the goods which are too long or too heavy for a single car. In order to overcome these shortcomings of the traditional cable transportation platform, such as the limitation of the mobile distance and the inconvenience, a set of double-car Linkage control system based on wireless control is designed. The difficulty of this system is how...
Currently, there are increasing demands for unmanned aerial vehicle (UAV) in urban application. UAV based on mobile communication network has further breached the limit of transmission distances. Taking into account the inherent characteristics of communication network infrastructures such as blind spots in distribution and space loss, this paper uses the wireless communication model of base station...
