Abstract
A wireless network having a plurality of access points that automatically share positional information with each other without using a central server is disclosed. Each access point includes processor to generate location information associated with the respective access point, a location table having a plurality of entries each for storing location information associated with a corresponding one of the plurality of access points, and a transmitter to automatically broadcast all location information stored in the location table to other visible access points in response to an update in one or more of the entries.
Claims22
A method for sharing location information across a wireless network having a plurality of access points, the method comprising:
- determining first location information associated with a first access point;
- broadcasting the first location information from the first access point to a second access point that is directly visible to the first access point;
- storing the first location information in a location table provided within the second access point;
- and
- automatically broadcasting, in response to the storing, the first location information from the second access point to a third access point that is directly visible to the second access point.
A wireless network having a plurality of access points configured to automatically share positional information with each other, wherein a respective access point comprises:
- a processor to generate location information associated with the respective access point;
- a location table, coupled to the processor, having a plurality of entries each for storing location information associated with a corresponding one of the plurality of access points;
- and
- a transmitter, coupled to the processor, to automatically broadcast all location information stored in the location table to other visible access points in response to an update in one or more of the entries.
A system for sharing location information across a wireless network having a plurality of access points, the system comprising:
- means for determining first location information associated with a first access point;
- means for broadcasting the first location information from the first access point to a second access point that is directly visible to the first access point;
- means for receiving the first location information in the second access point;
- and
- means for automatically broadcasting, in response to the receiving, the first location information from the second access point to a third access point that is directly visible to the second access point.
