Users have everything on their fingertips and to support them, there are scores of application which add to the usability and comfort. \"Know your world better\" is an Augmented Reality application developed for Android. This application helps the user to find friends and locate places in close proximity. In this paper we talk about an application that describes a method of augmenting Point of Interests POI's on a mobile device. User has to move his phone pointing in a direction of his choice and POI's if any are shown in real time. The user's interest with respect to the environment is inferred from speech or by selecting from the choices; this data is used for information retrieval from the cloud. The result of context-sensitive information retrieval is augmented onto the view of the mobile and provides speech output.","PeriodicalId":265963,"journal":{"name":"Int. J. Handheld Comput.

Localization is a process of achieving the location information using nodes which already have location information. WSN's generally have limited nodes with given location information or a capability of getting their locations using Global Positioning System GPS. Therefore, it is important that wireless nodes have capability to localize. In this work the authors use Time of Flight TOF ranging technique to measure distances between nodes. These distance measurements are then used by trilateration/multi-lateration techniques which require distance measurements between three or more nodes to estimate location. Focus is to a find a trade-off between energy consumption and the location accuracy. For experiments we use SIDnet-SWANS simulator to two different WSN topologies. Experimental results show that accuracy achieved is relatively better without significantly draining the batteries. The results show the trade-off between accuracy and energy, which can be efficiently used by different applications.","PeriodicalId":265963,"journal":{"name":"Int. J. Handheld Comput.

The proposed Mobile Application's Offloading algorithm enables to shift applicative jobs from mobile handsets to remote servers. The novelty of MAO consists in considering the Quality of Experience as an additional decision test before proceeding to application offloading. Based on various traffic scenarios, researchers study the efficiency of the MAO algorithm and show its performance in terms of rejected jobs and energy savings. First, the researchers consider the case where the application servers were placed systematically at the antenna's site. For a more realistic context of Mobile Cloud Computing, they extend the analysis by considering the case where the remote servers can be placed at different splitting points of the infrastructure. They assess by means of closed-forms fitting functions the performance of the MAO algorithm. Authors end this article with proposing an optimized applications servers placement.","PeriodicalId":265963,"journal":{"name":"Int. J. Handheld Comput.

However, the professional network has a great number of users who generate huge amount of information every day, which makes it difficult for the hiring company to distinguish reliability of users' information and evaluate their professional abilities. In this context, this article bases on LinkedIn Mobile as the online professional social network and proposes a research approach to effectively identify unreliable information and evaluate users' abilities. First, the authors look for relevant social network profiles for a cross-site check. Second, on a single professional social networking they site, the authors check the similarity between the user's background and his connections' backgrounds, to detect any possible unreliable information. Third, they propose an algorithm to rank the trustfulness of users' recommendations based on a PageRank algorithm that was traditionally to evaluate the importance of web pages.","PeriodicalId":265963,"journal":{"name":"Int.

After an overview of the literature, the authors propose a scalable and lowcost car parking framework CPF based on the integration of aforementioned technologies. A preliminary prototype implementation has been performed, as well as experimentation of some modules of the proposed CPF. The results demonstrate proof of concept, and particularly reveal that the proposed approach for WSN deployment considerably reduces the cost and energy consumption compared to existing solutions.","PeriodicalId":265963,"journal":{"name":"Int.

Several opportunities and methodological challenges arise from having little or no access to users, other than through the application itself. So far, researchers have needed to hardcode survey items into the software application studied, which is laborious and error prone. This paper discusses how these problems are addressed using TEMPEST, a platform for longitudinal in situ data collection. The authors illustrate the use of TEMPEST to study the deployment and real-world use of a tablet application called idAnimate; this application has been designed to support the creation of simple animations as design representations during the creative design process. The authors discuss how the tool has supported the gathering of data in over 4000 installations, both from a development and research perspective, and relate their experiences to current research perspectives on large-scale app trials.","PeriodicalId":265963,"journal":{"name":"Int.

Each agent can be treated as an embedded system with its own sensors and actuators. Under the assumption that agents have limited sensing capabilities, the distributed computing algorithm is designed to make agents cover the convex region so that each member's individual region, the space around them, is optimized. Each agent must accommodate its kinematic constraints and can only exchange information locally based on the range of the sensors equipped. The proposed algorithm utilizes Voronoi partitions to create individual subregions and directs each member toward the centroid of their subregion. The Voronoi partitions are updated with each iteration of the algorithm. Simulation results are provided to validate the proposed algorithm.","PeriodicalId":265963,"journal":{"name":"Int. J.

In this paper the authors review some of their work associated with polarization and space-polarization architectures, including channel modeling, sounding and parameter estimation to assist in the development of frequency-selective parametric models for performance characterizations; wideband polarimetric signal suppression; adaptive transmission for interference avoidance; and linear precoding with adaptive power control for energy-efficient communications in packet erasure channels.","PeriodicalId":265963,"journal":{"name":"Int.
