As many geo-located web services will be deployed in the future, the mobile clients will be interested in locating a specific application server based on requirements such as proximity, service cost per location area, bandwidth and server utilisation rate. This paper presents a middleware system named GLWSA (Geo-Located Web Services Architecture) that aims at satisfying these requirements as we...

This paper presents an experiment that allows the inference over data published in social networks, resulting in a potentially severe privacy leak, more specifically the inference of geo-location resulting in the potential of cybercasing attacks. We present an algorithm that allows the inference of the geo-location of YouTube and Flickr videos based on the tag descriptions. Using the locations,...

place is a part of geographical space and a base for establishment of social relations. each place is unique according to its specific properties, functions and history. meanwhile, some places find symbol identity due to their especial historical events and properties and this identity would be maintained in the minds and moved to the other generations. for example azadi tower in tehran and sav...

Data security in a mobile context is a critical issue. Over the last few years a new category of location-based services, the Enterprise LBS (ELBS), has emerged focusing on the demands of mobility in organisations. These applications pose challenging requirements, including the need of selective access to ELBS based on the position of mobile users and spatially bounded organisational roles. To ...

<p>Due to the extensive use of social media and mobile devices, unbounded massive data is generated continuously. The need process this big increasing day by day. traditional processing algorithms fail cater various applications such as digital geo-based advertising, recommendation systems. There has been a high demand continuous spatial fuzzy textual queries over stream spatial-textual o...

Ad hoc wireless networks have become the architecture of choice for peer to peer communications in areas where the telecommunications infrastructure is inadequate or has failed. A major challenge is the reliable delivery of data when nodes move. The reliable Internet protocol is TCP. However, TCP performs poorly in mobile ad hoc networks, mainly because of route breakage. To overcome this probl...

Such a universal term, prosperity, derived from the Latin word 'prosperus', middle English 'prosperite', and French 'prosperitas', meaning favourable or fortunate. Recent intensive engagement with prosperity has denounced economic monopoly over it to integrate dimensions that are social, environmental, ecological, physical. This movement, further catalysed by UN-Habitat (see UN-Habitat, 2015, 2...
