Wireless mesh network with pinch point and low battery alerts
WO 2010036885 A3
Abstract
A wireless mesh network includes a plurality of wireless devices and a gateway organized in a multi hop mesh topology. Each wireless device maintains and reports radio statistics to the gateway, and also reports battery conditions of its power source. The device manager communicates with the gateway and provides an alert indicating existence of a pinch point within the mesh network based upon the radio statistics. When a low battery condition is reported by a device, the device manager determines whether loss of that device is a pinch point or will cause a pinch point, and provides a low battery alert prioritized based upon the pinch point analysis.
