摘要： Disclosed are methodology and corresponding apparatus subject matters for providing improved efficiency in the collection of data from a large number of metrology devices associated with an Automated Meter reading (AMR) network. AMR network operation produces randomly spaced transmissions from individual nodes in the network. When an AMR system wishes to retrieve data from a large number of points over an AMR network, a broadcast or multicast request is transmitted to appropriate nodes. A time window is defined either in such request or in the devices themselves such that start and end offsets from the time of the request are received by the node. The start offset provides a quiet period to insure request delivery to all the appropriate nodes. The end offset provides a time by which the requested data must be returned. Responses are sent randomly within the window established by the start and stop offset times.

摘要： A new device is deployed to an area in which a network is provided. The new device may join the network using a single handshake via a neighboring device that is a member of the network and register with a network management system managing the network. If the network is overloaded or has limited bandwidth remaining, the network may refuse to admit the new device, or if the new device is isolated, may force some devices that are members of the network to leave or migrate from the network to allow the isolated device to join the network.

摘要： An infrastructure for securely communicating with electronic meters is described, which enables secure communication between a utility and a meter located at a customer, over a communication link or connection such as via a network. This enables messages to be sent from the utility to the meter and vice versa in a secure manner. The network provides a communication medium for communicating via the C12.22 protocol for secure metering. A cryptographic backend is used to cryptographically process messages to be sent to the meter and to similarly cryptographically process messages sent from the meter. By providing appropriate cryptographic measures such as key management, confidentiality and authentication, the meter can only interpret and process messages from a legitimate utility and the utility can ensure that the messages it receives are from a legitimate meter and contain legitimate information.

摘要： Generally described, the disclosed subject matter is directed to improved processes for securely accessing a meter. In accordance with one embodiment, a method for providing a mobile meter reader with an authorization that may be used to establish a secure session with a meter is implemented. In particular, the method includes issuing a request for authorization to access the meter from the mobile meter reader. If the mobile meter reader maintains sufficient rights, an authorization having an encoded digital signature is generated at a host computer system and provided to the mobile meter reader. Then the method formulates and transmits an authorization command to the meter having the encoded digital signature that was generated by the host computing system.

摘要： Disclosed are apparatus and methodology subject matters for upgrading firmware associated with one or more metrology devices and adjunct devices. Methods are disclosed for broadcast transmission of portions of a firmware image file from an originating device over a network connecting multiple devices to be upgraded. The entire image file may be transmitted as segments to be assembled by the end devices. Broadcast segments not properly received from the originating device may be retried directly from the originating device or from neighbors correctly receiving the segment. A viral propagation methodology is disclosed as an alternative to portions of the broadcast methodology.
