Determining a physical location of a wireless mobile device
First Claim
1. A computer system to determine the physical location of a mobile wireless device, the computer system comprising:
- one or more computer processors, one or more computer-readable tangible storage devices, and program instructions stored on one or more of the computer-readable tangible storage devices for execution by at least one of the one or more processors, the program instructions comprising;
program instructions to receive 1-hop neighbor information from a mobile wireless device, wherein the 1-hop neighbor information comprises identities of one or more wireless neighbors of the mobile wireless device responding to a discovery request transmitted by the mobile wireless device in an ad hoc wireless communications protocol;
program instructions to receive 2-hop neighbor information from each of the one or more responding 1-hop wireless neighbors of the mobile wireless device, wherein the 2-hop neighbor information comprises the identities of one or more wireless second-hop neighbors associated with each of the one or more responding 1-hop wireless neighbors of the mobile wireless device;
program instructions to determine a physical location of the mobile wireless device based in part on;
fixed physical locations of wireless devices stored in a database that correspond to the one or more wireless devices responding to the discovery request transmitted by the mobile wireless device; and
an area in which the mobile wireless device is in a transmission range of each of the one or more 1-hop wireless neighbors of the mobile wireless device responding to the discovery request that are associated with a fixed physical location; and
an area in which the mobile wireless device is in a transmission range of each of the one or more responding 1-hop wireless neighbors of the mobile wireless device that are not associated with a fixed physical location, where each of the responding 1-hop neighbors not associated with a fixed physical location is in the transmission range of its associated second-hop wireless neighbors that are associated with fixed physical locations.

Abstract
Determining the physical location of a mobile wireless device. A computer receives 1-hop and 2-hop neighbor information from a mobile wireless device for neighbor devices of the mobile wireless device responding to a discovery request transmitted by the mobile wireless device in an ad hoc wireless communications protocol. The computer determines a physical location of the mobile wireless device based in part on stored fixed physical locations of responding devices; an area in which the mobile wireless device is in range of responding 1-hop neighbors associated with a fixed physical location; and an area in which the mobile wireless device is in range of responding 1-hop neighbors not associated with a fixed physical location, which are in the range of 2-hop neighbors associated with fixed physical locations.
