Location awareness refers to a presence-technology component that provides information about the physical location of a device to another application or user. This term is frequently used to refer to cameras and mobile communication devices; however, it may also be used with websites that request the zip code of a user for delivering targeted information.
Location awareness also signifies devices that feature the ability to actively or passively discover their location. For vehicles and vessels, navigational instruments offer location coordinates. Surveying devices recognize the location with regards to a popular locational wireless communication device. Network location awareness (NLA) represents the location of a node within a network.
The location of a device is often identified using one of the three methods:
Global positioning system (GPS) satellite tracking
Media access control (MAC) address of a device in a Wi-Fi network
Location awareness is a rapidly growing trend when it comes to software and hardware. Listed below are a few applications of location awareness:
Navigation: Navigation as well as reckoning are main worries for aviators, seafarers and professional drivers. The job is to dynamically identify the present location and also the distance, direction and time to the destination.
Surveying: It's the static complement to navigation. It is vital for delineating land ownership and also for civil engineers and architects who design construction projects.
Memory cards of cameras, which automate the location tagging of a picture
Applications or software programs on smartphones
GPS systems used in vehicles
Healthcare device management
Supply chain management (SCM)
Warehouse and routing
Concerns regarding security and privacy grow with the prevalent usage of location awareness. The Internet Engineering Task Force (IETF) includes a working group known as Geographic Location/Privacy (geopriv) for exploring strategies to protect users while advancing the technology.
