1. Methodology for an end device within an advanced metering system frequency hopping network to handle a synchronization request from another end device, comprising:

  • providing a frequency hopping network including a plurality of end devices, at least some of which end devices comprise metrology devices;

    configuring the plurality of end devices for bidirectional communications with other end devices;

    receiving a synchronization request at a given end device from a neighboring unsynchronized end device; and

    determining whether the given end device has received within a predetermined number of recent time slots a message from a father end device by which the given end device has been synchronized, and if so, then transmitting a synchronization acceptance signal to the requesting unsynchronized end device;

    or if not, then transmitting a beacon request signal to a registered father end device.
