1. Methodology for an advanced metering system mesh network with self-optimizing uplink communications, comprising:

  • establishing a network including a central facility and a plurality of end devices, at least some of which end devices comprise metrology devices, and at least some of which end devices comprise cell relays which provide communications between others of the end devices and the central facility;

    configuring the network for bi-directional communications between the central facility and each of the plurality of end devices via associations with respective of the cell relays;

    computing an average local propagation delay for each one-hop link for uplink communications from end devices towards its associated cell relay;

    computing global average propagation delay along each uplink path from an end device to its associated cell relay; and

    optimizing the global average propagation delay at at least one of said end devices,whereby uplink communications from such at least one of the end devices to the central facility are optimized without requiring storage of a routing table.
