Abstract
A network node is configured to monitor battery usage on behalf of the low power device and to predict the SOC and remaining life-time for the batteries in the low power devices. The network nodes are fully powered and have the computational capacity to use more complex and accurate models that are not feasible for implementation in resource-limited devices. The network node can calculate the SOC and remaining life-time for a low power device and may also change the transmission and reception patterns for the device to extend the life-time of the battery.
