In this paper, we propose a condition-based location authentication protocol for mobile devices to authenticate users' location claims. This protocol collaborates with other neighboring mobile devices to generate the trusted proofs. This protocol does not require any extra equipment built in mobile devices, thus, it is easy to use and deploy. Through the security analysis, our protocol is more secure...
The alluring benefits of Mobile Cloud Computing have attracted many mobile device users. The moving property of the mobile devices can serve as the boon to its user but curse for its developers. The moving devices cause the problems of the link faults, less available resources and unreliable dynamic networking conditions. The link failure of the nodes in the changing network decreases the performance...
Based on C/S (client/server) and B/S (browser/server) hybrid construction, a paper-free leaflet system was designed in this paper. The proposed system consists of the database, servers and clients. This system now has such functions as leaflet push, seat selection, ticketing systems, and information interaction between the organizers and participants. Leaflets issued subsystem adopts modular design...
Mobile Edge Computing (MEC) provides computation capabilities within the radio access network and in close proximity to mobile users, so as to enrich user experience. In this paper, we consider a multi-cell MEC scenario, where the small cells are densely deployed and serve multiple mobile users. However, the finite computation resources of MEC server and severe inter-cell interference limit the scalability...
Mobile users run complex applications increasingly, requiring much more computing power and energy. Cloud-enhanced small cell networks, endowing small cells with cloud computing abilities, extend mobile devices capabilities and battery lifetime by providing them with the advantages of instant and high-rate access to the cloud servers. However, conventional offloading policy can not fully exploit these...
In this paper, we design and implement a face-based signage interacting system, called AdYou, for mobile users using smartphones. By using the AdYou system, mobile users only need to drag the service icon on the face of a particular target in a digital signage. AdYou is able to provide diverse services to mobile users through face detection and recognition techniques. Using the intuitive way of gesture-based...
Location based services (LBS) is one of the new technologies to gain a position in the geographic presence of mobile devices. The presence of LBS technology can be used for information mapping of an area such as the existence of the event. The existence of event is influenced by the number of visitor to the event, because it can be attract people to attend the event. Haversine formula is the method...
Smart spaces support development of advanced service-oriented applications that introduce intelligence into Internet of Things environments. Current development meets the performance challenge, since the intelligence is achieved by the cost of performance. In this paper, we experimentally study a representative application for smart spaces — the SmartRoom system. It assists humans in such collaborative...
Smartphones have become the most convenient and ubiquitous interface for Internet services. They are equipped with a multitude of sensors that can significantly improve the user's cognitive ability. Face recognition is one of the fastest growing applications in mobile domains due to the wide range of potential uses. However, face recognition is a computation-intensive process and requires resources...
In this paper, we present the Physical Web Browser project for web applications depending on the environment. At this moment, many of users all over the world visit websites using their mobile devices only. Any mobile device (e.g., smartphone) has sensors to capture the environmental information. This information (context) could be analyzed and used within the web applications. There are, at least,...
The thin-client approach for gaming is becoming more popular. For instance, Nvidia Shield, Valve Steam and Shinra technologies have offerings based on the concept. In remote cloud gaming, the game is being executed and processed in the cloud while the user receives a video and audio stream of the game, in a very similar way as with remote desktop clients. At the same time, clouds are moving towards...
This paper presents the development of a remote experimentation for automatic control engineering education. By using a smartphone application, students can interact with real laboratory didactic equipment. Through a friendly graphical user interface and information provided by built-in smartphone sensors, students can modify the process parameters and verify in real time what's happening on the experimental...
This paper introduces the design and implementation of a Bluetooth based on indoor location tracking system. This system utilizes the integrated Bluetooth modules in any today's mobile phones to specify and display the location of the individuals in a certain building. The proposed system aim for location tracking/monitoring and marketing applications for whom want to locate individuals carrying mobile...
In Today's world Mobile devices are the important handheld devices spreading throughout the world, and it is necessary to integrate web services into the mobile device. We introduce a simple approach for dynamically invoking web service methods from mobile devices with minimal user intervention that only involves entering a search phrase and values for the method parameters. This energy efficient...
Technology has transformed the mobile phone as a big medium for communication and offered a pool of services to the subscriber. Among those services, Location Based Services (LBS) is prominent to get services based on current geographic location. The services include right from information to entertainment and the services offered by LBS are highly dynamic because its access pattern is different from...
Mobility is one of the major feature in the present computing environment and in the present era of computing almost all the mobile devices have the ability that they can easily be move from one location to other and the data reside on a single system can be utilize via other systems generally using the client-server paradigm . The mobile device can extract needed amount of data from the server and...
Patient health records that can be retained on portable devices, require secure and efficient access control. This work presents Proof Carrying Authorization(PCA) for accessing a mobile based health card, which provides an efficient method for data security. Access control over resources is a mechanism by which each client's request is granted access by scrutinizing against the logic of application...
Mobile devices connections to heterogeneous networks require the management of the network interfaces, as well as addressing service for each access network. However, the frequent association and dissociation of devices to the network and several communications patterns hamper the address control and negotiation. In general, addressing strategies for heterogeneous wireless networks are individualized...
Location based services are widely being adopted by many commercial applications where mobile users receive incentives/rewards based on their location. In such applications, mobile users may submit their location with the assistance of various location apps which are capable to locate the mobile devices. However, there is always a possibility that users may submit false location to the service providers...
We present a method for recognizing a video that is playing on a TV screen by sampling the ambient light sensor of a user's smartphone. This improves situation awareness in pervasive systems because the phone can determine what the user is currently watching on TV. Our method works even if the phone has no direct line of sight to the TV screen, since ambient light reflected from walls is sufficient...
