Event-based Communication for Location-based Service Collaboration
نویسندگان
چکیده
Location-based context-aware services for mobile users need to collaborate in disparate networks. Services come and go as the user moves and no central repository is available. The user’s personal information and service usage statistics need to be protected. To support service collaboration we propose a service infrastructure that relies on an event-based serviceoriented architecture. We implemented a basic version of the architecture and used it for a tourism information system. An advanced version has been modelled using formal methods to evaluate privacy aspects. This paper reports about both architectures and our experiences of their application to tourismrelated services.

متن کاملQuasi Random Deployment Strategy for Reliable Communication Backbones in Wireless Sensor Networks
Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...
متن کاملSink Location Service Based on Fano Plane in Wireless Sensor Networks
Sink location is considered as a basic service in geographic routing in wireless sensor networks. Obtaining the location of sink node by source node using an efficient method with low complexity has always been a challenging issue in research. In this paper, a sink location algorithm based on Fano plane is proposed. The research challenge is how to ensure the intersection of two SLQ (Location Q...

We describe a map-based location-based service ‘GeoHealth’ for home healthcare workers who attend patients at home within a large geographical area. Informed by field studies of work activities and interviews with care providers, we have designed a mobile location-based service prototype supporting collaboration through information sharing and distributed electronic patient records. The GeoHeal...
متن کاملHotspot Based Mobile Web Communication and Cooperation: ABRI+ Bus Shelter as a Hotspot for Mobile Contextual Transportation and Social Collaboration
In this research and development project we are exploring a new approach of mobile web and location-based services (LBS) for communication / collaboration which is based on a physical hot spot serving as an accumulation point; a hub for thematic and social collaboration. Different actors can consult, publish or exchange information in relation with the location materialized by the hot spot. Thi...
