A Glimpse into the Research Space of Location Based Services

Abstract

Location Based Services are becoming an integral part of the wider telecommunication scenario. However, the approaches to provide Location Based Services and the research issues in this area are diverse and broad. In this paper, the present state of the Location Based Service systems has been analyzed. The analysis confirmed the heterogeneity of the research problems associated with Location Based Services as well as the array of solutions to address these problems. On one hand, the study carried out will enable one to get some idea about essential features for the implementation of a Location Based Service system. On the other hand, it is strongly believed that this study will assist researchers and the industry to get a sense of the multidimensional research space of Location Based Services which will be helpful for later exploration of this field

Design and Development of a Location-Based Social Networking Mobile Application

“…Maps are one of the important visual cues in the case of location as they aid the user to view his or her position with respect to other elements in the app. However, the difficulty of rendering maps due to excessive bandwidth consumption must be considered, as well as privacy aspects of displaying location [1]. In this regard, studies [1,2,3] emphasise the importance of giving users the control and choice to specify the situations where they want to reveal their location and also allow them the flexib ility of choosing how it is displayed to other users.…”

“…However, past studies conducted in investigating users' perception towards sharing their location in a mobile platform, have contradicting viewpoints. For example, Tan et al [1] highlights that users are reluctant to share their location with unknown users and discuss privacy controls to limit display of such information. On the contrary, Barkuus and Dey [5] state that the willingness of a user to share their location is direct ly correlated to the usefulness of the app to the user.…”

Location-Based Services in a Smartphone

“…Global Positioning System (GPS) is widely used for the Location-Based Service (LBS) of smartphones. However, GPS dramatically increases the energy consumption of a smartphone due to heavy computation overhead [1][2][3][4][5][6][7][8][9][10]. Specifically, a GPS receiver in a smartphone polls signals from multiple satellites continuously and calculates the threedimensional location (latitude, longitude, and altitude), which increases the energy consumption of a smartphone dramatically [12].…”
