摘要：Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The risks to users of wireless technology have increased as the service has become more popular. Wi-Fi can be less secure than wired connections (such as Ethernet) because an intruder does not need a physical connection. By any chance if the wireless device attacked by intruder it is hard to locate the device. Locating a wireless device in a Wi-Fi network by calculating the distance of each node and localize the wireless accurately. A common measure to deter unauthorized users involves hiding the access point's name by disabling the SSID broadcast. While effective against the casual user, it is ineffective as a security method because the SSID is broadcast in the clear in response to a client SSID query. Another method is to only allow computers with known MAC addresses to join the network. The robust location estimation assumes the reference location in the target environment, the proposed location system maps the input to the physical location using RSS algorithm. In SSID is the application software used to list the set of wireless device available in the surrounding and it used to create a gpx file. Converting gpx file in a table format for further distance estimation.
