“…In the TOA trilateration technique, the location of MS is determined by a single intersection point of three circles with center coordinates of three BSs and radius corresponding to the distance between MS and each BS [7]- [8]. Trilateration approach for MS location at a single point is shown in Figure 1.…”

The TOA trilateration method decides the location of MS using an intersection point of three circles with centers corresponding three base station (BS) coordinates and radius based on the distance between MS and three BSs. Since the distance between BS and MS is generally estimated counting the number of time delay samples, the estimated distances are slightly increased and three circles may not intersect at a point. In this paper, we introduce the shortest distance and line intersection algorithms for improving conventional TOA trilateration method to resolve above problem. Also, the mathematic analysis is provided to indicate the relation between both algorithms.

“…If the value of the result is positive, the Location Server forwards the request including IDJ to the Location Generator. The Location Generator contacts J, as identified by IDJ , and retrieves its location in some way; see, for example, [2, 17,18]. The Location Generator sends the location object associated with IDJ to the Location Server, which sends it back to T .…”

“…If the Location Recipient is authorised to retrieve the location of the Mobile Device, the Location Server forwards the request to the Location Generator. Next, the Location Generator obtains and/or measures the Mobile Device location, and creates a location object describing the Mobile Device location (for possible means of locating a Mobile Device see, for example, [2, 17,18]). The Location Generator then transfers the location object back to the Location Server, which specifies whether the Location Recipient can receive the location object and how it should be filtered for this Location Recipient.…”

This paper focuses on creating a secure domain consisting of all devices owned by a single owner. This domain allows secure content sharing between devices in each domain and prevents the illegal copying of content to devices outside the domain. This paper proposes a novel solution for binding a domain to a single owner, ensuring that only a single consumer owns and manages each domain. This enables binding of domain licences to a domain owner, thereby limiting illicit content proliferation.Our novel idea involves the use of location based services, ensuring that devices, when joining a consumer domain, are located in physical proximity to the domain registered addresses. This restricts domain membership to devices in predefined geographical locations, helping to ensure that a single consumer owns and manages each domain. In addition, the proposed scheme helps to protect consumer privacy; location-based service is only required for managing domain membership, and it is not required for creating, downloading or exchanging content; in addition, the proposed scheme uses the Geographic location/privacy protocol (Geopriv), which enables domain owners to control the precision or resolution of location data, and when, in which location, and by whom their location can be retrieved.

“…The authors in (Samiei, Mehrjoo, Pirzade, 2010) suggest applying signal attenuation as weights in the cost function of the time-based methods to improve the measurement accuracy. In the hybrid method which has been proposed in (G. Kbar, W. Mansoor, 2005), the signal strength has been used to estimate the timing delay which is compared with the measured time of arrival. The average of the minimum timing value of the two results can then be used in measurement.…”

ABSTRACT:Earthquakes are among the most destructive natural disasters. Earthquakes happen mainly near the edges of tectonic plates, but they may happen just about anywhere. Earthquakes cannot be predicted. Quick response after disasters, like earthquake, decreases loss of life and costs. Massive earthquakes often cause structures to collapse, trapping victims under dense rubble for long periods of time. After the earthquake and destroyed some areas, several teams are sent to find the location of the destroyed areas. The search and rescue phase usually is maintained for many days. Time reduction for surviving people is very important. A Geographical Information System (GIS) can be used for decreasing response time and management in critical situations. Position estimation in short period of time time is important. This paper proposes a GIS based system for post-earthquake disaster management solution. This system relies on several mobile positioning methods such as cell-ID and TA method, signal strength method, angel of arrival method, time of arrival method and time difference of arrival method. For quick positioning, the system can be helped by any person who has a mobile device. After positioning and specifying the critical points, the points are sent to a central site for managing the procedure of quick response for helping. This solution establishes a quick way to manage the post-earthquake crisis.
