in this paper we proposed a cellular automaton based local algorithm to solve the autonomously sensor gathering problem in mobile wireless sensor networks (mwsn). in this problem initially the connected mobile sensors deployed in the network and goal is gather all sensors into one location. the sensors decide to move only based on their local information. cellular automaton (ca) as dynamical sy...

Mobile Geographical Information System (Mobile GIS) is a Geographical Information System based on mobile computing and mobile Internet. It is not a conventional GIS modified to operate on a smaller computer, but an extension of Web GIS to mobile Internet including wireless Internet/Intranet and mobile communication network. But architectures of Web GIS are unsuitable for Mobile GIS, because of ...

In 2003, an internet-based monitoring system of influenza-like illness (ILI), the Great Influenza Survey (GIS), was initiated in Belgium. For the Flemish part of Belgium, we investigate the representativeness of the GIS population and assess the validity of the survey in terms of ILI incidence during eight influenza seasons (from 2003 through 2011). The validity is investigated by comparing est...

In this paper I will show how social network analysis techniques can be used for understanding GIS diffusion at a national scale. In particular, two network models, cohesion and structural equivalence, are explored in the context of the emerging Greek GIS community. A map of this community based on GIS teams and linkages is put forward, and two social constructs, institutional setting and disci...

There has been a great development in Wireless GIS (WGIS) new century. Spatial data transferring and storage in GIS are developed from wired to wireless network. This paper first briefly introduces the technologies and strategies of spatial data transferring and storing in distributed Wireless GIS. Secondly, the schemes of spatial data transferring modes in wireless GIS for improving the networ...

We consider the problem of determining how similar two networks, without known node-correspondences, are. This problem occurs frequently in real-world applications like transfer learning and change detection. Many network similarity measures exist, and it is unclear how one might select from amongst them. We provide the first empirical study on the relationships between different network simila...
