“…Due to the evolving nature of technological innovation, mobile GPS receivers sensitivity will increase still further, thus, obtaining more precise and accurate results than those here obtained (Cao et al 2003;Elnahas & Adly 2000;Schiller & Voisard 2004) Also, both iOS and Android devices used in the verification process performed quite well in terms of power consumption throughout the working hours without battery recharges, and this is specially important taking into consideration the typical battery drain usually associated to the GPS receiver circuit.…”

This paper analyzes the viability of the use of employees' smartphones following the BYOD paradigm as a valid tool for companies in order to conduct presence control (primarily for remote workforce). A Mobile Information System is also proposed for Presence Control using exclusively terminal-based reactive location technologies, meeting cost minimization and universal access criteria. Qualitative and quantitative references are proposed, adequate to the location information accuracy demanded in different business remote workforce control scenarios, and taking into consideration the strictest international regulation in force relevant to the location of individuals in Emergency Systems, promoted by the North American FCC. A prototype for the proposed Information System was developed to evaluate its validity under different real world conditions, and valuable information was obtained on the accuracy and precision of location data using real devices (iOS and Android) under heterogeneous connectivity conditions and workplace premises.

“…Usually, a user profile reflects his movement pattern, in the form of a set of location areas, and the probability of locating him in each of these areas. A survey of such work can be found in [6]. Furthermore, the use of profiles in performing advance reservations in wireless networks proved in [4] to enhance the quality of service provided to mobile users.…”

This paper addresses some of the challenges associated with providing location-based services to mobile users in areas of sudden density increases. We adopt a profilebased peer to peer mode that allows host queries, upon density increase, to obtain their data from built in logical entities within our system called autonomous systems. Autonomous systems are a composite of elite mobile devices selected upon the occurrence of sudden density to cache service data. This work expands on a previously published work by us that demonstrated how sudden densities are detected, how autonomous systems are selected and formed, and how data is cached. In this paper, autonomous systems formation, distribution, and record caching are made highly sensitive to individual users profiles. Simulation and experimental results demonstrate that this approach decreased the latency associated with service lookups as well as increasing the ability to accommodate more mobile users at times of disrupted services.

Abstract-Mobile telephony adoption is on the rise, with industry projections suggesting that wireless subscribers will reach 100 billions in India. Recent technological innovations have also dramatically enhanced the capabilities of the wireless telephone; it is one of the most important technologies to track the location of the mobile users. In mobility management basically is performed by two databases, HLR database and VLR database. A mobile user moves anywhere in mobile networks from one LA to another LA in networks, so location registration for call tracking is always needed. An understanding of the issue is some critical to handle with traditional centralized databases. The proposed intelligent database system has the ability to produce good technology in terms of database retrieval and punctual functioning of mobile station systems-technology that is innovative, useful, usable and profitable. Fuzzy Logic plays a major role in extending intelligent database system. It is also proposed to simulate the fuzzy databases.
