Abstract
A network server selects a gateway, from among a plurality of alternative candidate gateways, to use for downlink wireless communication to an end node (EN) based on additional factors in addition to RSSI. Exemplary additional factors include: SNR, gateway loading, message loading, backhaul network loading, device type, application type, application priority, operator preferences, device/application black-lists, white-lists, and red-lists, number of devices, number of transmitting devices in a given time interval, operator rules and priorities. In some embodiments, the network server calculates a composite weighted metric (CWM) for each of the alternative candidate gateways which may be used for downlink, subject to operator policy rules, and selects to use a gateway based on the results, e.g. selects the gateway with the highest CWM.
