Abstract

Embodiments include peer-to-peer ad hoc network having a group having a plurality of members, each of the plurality of members comprising a locating device, wherein the plurality of members are configured to detect an absence of one of the plurality of members from the group. The system also includes a location server configured to communicate with the locating device of at least one of the plurality of members and a supervisor device configured to receive an alert from the location server, wherein the alert is generated by the location server in response to a detection of the absence of one of the plurality of members from the group.

Claims

1. A system comprising:

a peer-to-peer ad hoc network comprising a group having a plurality of members, each of the plurality of members comprising a locating device, wherein each of the plurality of members are configured to detect an absence of one of the plurality of members from the group;

a location server configured to communicate with the locating device of at least one of the plurality of members; and

a supervisor device configured to receive an alert from the location server, wherein the alert is generated by the location server in response to a detection of the absence of one of the plurality of members from the group and wherein the alert comprises a last time that the one of the plurality of members absent from the group communicated with another member of the group.

2. The system of claim 1, wherein the plurality of members detect the absence of one of the plurality of members from the group when none of the plurality of members have communicated with the one of the plurality of members during a predetermined time period.

3. The system of claim 1, wherein a member of the group is configured to communicate with each of the plurality of members of the group located within a distance of the member.

4. The system of claim 1, wherein the alert further comprises:

an identification of the one of the plurality of members absent from the group; and

a last known location of the one of the plurality of members absent from the group.

5. The system of claim 1, wherein the locating device comprises:

an interface;

a processing unit;

a communications device; and

a power supply.

6. The system of claim 1, wherein the interface is operable for configuring an operation of the locating device.

7. The system of claim 1, wherein the communications device is configured to communicate with the location server and with one or more members of the group.
