This paper presents an intelligent bus system and services with the force of the masses to provide real-time bus information. Consider that while waiting for buses on the road, we often have no idea about how long we have to wait for, or which bus we can take for a destination. The information that we can get is quite limited, this situation which motivates us to design and develop a real-time bus...
This thesis is based on the application of Internet of Things (IoT) and WebGIS in precision agriculture. Through analyzing the current development of precision agriculture in China and considering its advantages and shortcomings, we choose an ecology farm as an example to conduct a new precision agriculture management system (PAMS) based on the above two techniques. We designed the four architectures...
In wireless sensor networks, location information is essential for the monitoring activities. Accessing the locations of events or determining the locations of mobile nodes is one of basic functions of wireless sensor networks. Except for normal information, sensor nodes should also provide position information of sensor nodes. So it's necessary to have a reliable algorithm for localization. Using...
Opportunistic sensing allows to efficiently collect information about the physical world and the persons behaving in it. This may mainstream human context and activity recognition in wearable and pervasive computing by removing requirements for a specific deployed infrastructure. In this paper we introduce the newly started European research project OPPORTUNITY within which we develop mobile opportunistic...
Map service, the most frequently used service in mobile navigation application, is always the bottle-neck due to the continual map refresh, limitation capacity of wireless network and the vast data volume of the vector map. Data prefetching, responsible for fetching data from Map Server forehand, is considered to be an efficient way to increase map refresh. However, the sticking point is to decrease...
