It is well-known that, for various reasons, smartphone operating systems persistently store location data in local storage. Less well-known is the fact that various network applications (apps) do this too. This paper considers the issue if location data extracted from mobile phones can replace or complement the location data obtained from network operators. Experiments with Android smartphones ...

The water supply networks have always been of significance to researchers as a hydraulic system of transferring and distributing water. The pressure gradient is the main reason of water transfer in networks, and in case of non-standard pressure increase, the undesirable phenomenon of leakage occurs in the network. Leakage in urban water distribution networks causes water waste and enormous fina...

Location-based services (LBSs), such as location-specific contents-providing services, presence services, and E-911 locating services, have recently been drawing much attention in wireless network community. Since LBSs rely on the location information in providing services and enhancing their service quality, we need to devise a framework of directly using the location information to provide a ...

In the various fields of disaster management, choosing the best location for the Emergency Support & Supply Service Centers (ESSSCs) and the survivability of the network that provides the links between ESSSCs and their environment has a great role to be paid enough attention. This paper introduces a graph based model to measure the survivability of the linking's network. By values computed for ...

Abstract: Parking lots for electric vehicles (EVs) can make good utilization of the EVschr('39') battery capacity due to the large number of EVs. However, the location and size of parking lots will affect the distribution network condition. In this paper, a mixed-integer linear programming (MILP) model is proposed for locating and determining the optimal capacity of EVschr('39') parking lots co...

Along with the increasing the level of distribution network intelligence and the network complexity, the automatic fault location technology for distribution network is particularly important. But the traditional fault location methods based on one information source is impossible to locate the faults accurately because of there are losses or faults in the information from the distribution. So,...

the analysis of land use utility matrix based on human and natural criteria in residential areas is the necessity and issues that planners in urban and rural areas in terms of access to communication network, central location, weather, noise and etc are a turning point for how optimal use is of resources. the aim of this study is to identify the level of user desirability in rural areas of Bina...

earthquake location process has an important role in any seismological applications including seismic tomography etc. the relationship between the travel-time of seismic phases and earthquake hypocenter (latitude, longitude, depth) and origin-time is non-linear and many different linearized methods have been implemented in recent years to linearize the relationship. the principal underlying lin...

Compared with topology -based routing, location-based routing scales much better in large-scale mobile ad hoc networks. Location-based routing protocols assume that a location service is available to provide location information of each node in the network. Many location service protocols have been proposed in the literature. However, either they do not scale well in large-scale network environ...
