Different from the previous duster-based structure, in this paper, we present a grid-based load-balanced routing method (GLRM) that aims to use a controlled sink to achieve load-balance in a non-uniform distributed network. Cell-header election of each cell is based on three parameters, i.e. the number of data packets that nodes need to relay, the Euclidean distance to the mid-point of cells and residual...
Location-Based Service (LBS) has become more and more important with the rapid development of mobile internet, it as an information service mainly make use of geographic position of mobile phone to provide accurate services for consumers. LBS involves a mass of longitude-latitude data and mainly involves three problems: Point Query, Range Query, and K-Nearest Neighbors. The object of this paper is...
Mobile application services are growing sharply in China at present. However there is a great lack of human resources in this domain. Therefore, it is of great significance to cultivate people who are good at mobile application service development for social needs. The requirements for human resources in the mobile application services is overlapping, diverse, and practical, thus its curriculum includes...
In the next generation of wireless mobile communications, it can be visualized that heterogeneous networks including 3G cellular networks and WLAN are demanded to co-operate user-friendly in a seamless manner. Based on mobility of users, optimal session admission control for multimedia services is very important for improving performance in integrated 3G/WLAN networks. In this paper, a new dynamic...
In next generation of wireless mobile communications, it is demanded that users could visit Internet services through any kind of radio access technology. Monitoring of radio access network (RAN) is very important for reconfigurable terminals (RT) in Mobile Internet. It is the foundation of network cooperation and seamless access for user services. In this paper, a new RAN monitoring scheme based...
To achieve the analysis of characteristic and forecasting of the mobile communication traffic, a mobile communication traffic modeling and forecasting method by Least Squares Support Vector Machine(LS-SVM) is proposed. With this method, an on-line forecasting scheme is designed to realize short-time forecasting of the mobile communication traffic. The traffic data is provided by China Mobile Communications...
Context maintenance and discovery, which aim to represent, manage and share context information, have been discussed since context-awareness was presented in the 1990s. These become more challenging when being applied to a ubiquitous environment where dynamic and distributed computing happens anytime, anywhere. In this paper, a platform for ubiquitous context representation and its distribution is...
Target classification is an important enabling technology for the monitoring task in transportation sensing networks. In the paper the magnetic signal and seismic acceleration signal are collected, analyzed and transmitted for a mobile road target. A classification algorithm based on the sensor network is proposed, which adopts a peak and valley pattern of hybrid detection signals from different sensors...
