Heterogeneous Networks (HetNets) are an attractive way of increasing network throughput, expanding network coverage, and reducing energy consumption, but it may lead to the problems of high cost infrastructure investment and high computational complexity to mobile operators. In this paper, we propose a new paradigm for the deployment of HetNets in LTE-Advanced system, where the Donor evolved nodeB...
In this paper, a cooperative mobile target estimation approach based on interacting multiple model (IMM) algorithm is presented. We propose a dual-IMM estimator structure to improve the accuracy and robustness of mobile target localization and tracking in wireless sensor networks. Suppose that two sensor systems are affected by different levels of noises, the measured data can be first processed at...
Localization is one of the important for robots, this paper propose robot localization methods based on WSNs(wireless sensor network). In the WSNs, robots act as a mobile nodes, so the location method for WSNs' nodes can be used for robots. Range-based location method and range-free location method are discussed in detail in the paper.
A mobile GIS for field data collection is a system which can facilitate the entire process from indoor preparation, data collection, to data processing. It is a combination of positioning and wireless communication technologies. The paper aims to demonstrate how to design and implement such a mobile GIS. Data of the system consist of three parts: background reference layer, with which spatial reference...
To meet more and more complex recommendation needs, it is quite important to implement hybrid recommendations for mobile commerce. In this paper, we propose a design for open hybrid recommendation systems in mobile commerce, which could integrate multiple recommendation algorithms together to improve recommendation performance. First, three solutions for an open hybrid recommendation approach are...
In this paper, a hybrid recommendation architecture for mobile commerce system is presented based on agent and ontology technology. Working flow and components of the architecture are described to explain how system components work together. This architecture is a hybrid algorithm which integrates the results of specific recommendation algorithms. Based on this architecture, a restaurant recommendation...
