This article deals with a method to describe and manage spatial knowledge. Each georeferenced data is considered as an information source, whose location and value are independently described. The method proposed in this paper uses the information sources to infer the value of any request zone . This method is able to treat imprecise or uncertain, qualitative and quantitative data. It can be ap...

The L1-median is a robust estimator of multivariate location with good statistical properties. Several algorithms for computing the L1-median are available. Problem specific algorithms can be used, but also general optimization routines. The aim is to compare different algorithms with respect to their precision and runtime. This is possible because all considered algorithms have been implemente...

The Mobile IP Standard has been developed to support mobility over the Internet. This standard contains several drawbacks as in the cases where packets are routed via sub-optimal paths and significant amount of signaling messages is generated due to the home registration procedure which keeps the network aware of the current location of the mobile nodes. Recently, a dynamic hierarchical mobilit...

One characteristic of reasoning about location is the need to make use of noisy data with a range of possible interpretations. This paper presents four different algorithms that use a location ontology with ONCOR to resolve a value for location information from a range of potentially noisy sensor data, and compare their performance to three other more conventionally used algorithms. Our work ta...

Abstract Location cover models are aimed at siting facilities so as to provide service demand efficiently. These crucial in the management, planning and decision-making of systems public private sectors. As a result, location have been incorporated range GIS tools, either closed or open source. Among them, open-source tools advantageous due transparency reproducibility. Nonetheless, capabilitie...

People-centric sensing with smart phones can be used for large scale sensing of the physical world at low cost by leveraging the available sensors on the phones. However, the sensed data submitted by participants is not always reliable as they can submit false data to earn money without executing the actual task at the desired location. To address this problem, the authors propose ILR, a scheme...

In this paper we generalize source location problems with edge-connectivity requirements on undirected and directed graphs to similar problems on undirected and directed hypergraphs. In the undirected case we consider an abstract framework which contains the source location for undirected hypergraphs as a special case and which can be solved in polynomial time. For the directed case, the asymme...
