Abstract

A technique for operating an ad-hoc wireless communication network includes providing 400 a plurality of price checking stations 102 having wireless communication capabilities, designating 402 one of the price checking stations 102 as a master station in the ad-hoc network, and designating the remaining stations as slave stations 100, and communicating with devices 104-110 deployed in the network using the wireless communications capabilities of the price checking stations 100, 102.

Claims

1. A method for operating an ad-hoc wireless communication network, the method comprising:

providing a plurality of price checking stations having wireless communication capabilities, the price checking stations being connected in an ad-hoc wireless communication network;

designating one of the price checking stations as a master station in the ad-hoc network, and designating the remaining stations as slave stations;

communicating with the master station about devices deployed in the network using the wireless communications capabilities of the price checking stations;

informing the ad-hoc network that the master price checking station is leaving the network as the master station to instead perform a price checking function;

dropping the master price checking station from the network; and

transferring the master function of the dropped price checking station to another price checking station.

2. The method of claim 1, wherein the master station of the ad-hoc network is the price checking station having the highest wireless signal strength.

3. The method of claim 1, wherein communicating includes logging an employee badge into the master station using a price checking station and logging equipment checked-out to the employee badge into the master station using a price checking station to define an employee-equipment pair.

4. The method of claim 3, wherein communicating further includes tracking the employee-equipment pair.

5. The method of claim 3, wherein communicating further includes maintaining a log of employee-equipment pairs in the master station, and providing the log to the slave stations.

6. The method of claim 5, wherein if a price checking station detects either one, but not both, of the paired employee-equipment in the log, providing an alert.

7. The method of claim 5, further comprising deleting an employee-equipment pair at a slave station, which reports the deletion to the master station, which up-dates its log of pairs and notifies the other slave station of the same.

8. The method of claim 1, wherein communicating includes tracking locations of mobile communication devices that are wirelessly connected to particular price checking stations that are used as wireless access points in access point subnets, the tracking information provided to all slave stations in the network, and wherein communicating includes using the tracking information to call a closest-located mobile communication device within a callers own access point subnet.

9. The method of claim 8, wherein a closest-location of a mobile communication device can be refined using an available map of price checking station locations.

10. The method of claim 9, wherein if there is no mobile communication device within a local price checking station subnet, then locating a close-by mobile communication device is expanded to call proximal price checking station access point subnets that are increasingly further away from the price checker access point from which the call originated.

11. A price checking station having wireless communication capabilities operable on an ad-hoc wireless communication network consisting of a plurality of price checking stations, the price checking station comprising:

a scanner;

a wireless transceiver operable on the network;

a processor coupled to, and operable to control, the transceiver and scanner, wherein the processor is operable to communicate with the plurality of price checking stations to designate one of the price checking stations as a master station in the ad-hoc network, and designate the remaining stations as slave stations, and communicate with the master station about devices deployed in the network using the wireless transceiver;

wherein the ad-hoc network is informed that the master price checking station is leaving the network as the master station to instead perform a price checking function;

dropping the master price checking station from the network; and

transferring the master function of the dropped price checking station to another price checking station.
