A method and apparatus for coordinating communication in a wireless sensor network may include a plurality of nodes, such as routers, edge nodes, data accumulators and / or gateways. Time management functions, such as determining an elapsed time, may be controlled based on a detected temperature, e.g., a temperature detected at a node, and / or based on a detected clock skew between two or more clocks in two or more different devices. Accurate time management may allow for devices to more accurately coordinate communication instances, e.g., communication that occurs at periodic wake up times. A cluster head, such as a data accumulator, may be associated with a network after its initial formation and cause nodes in the network to alter their hierarchy in the network, thereby making the cluster headaccumulator a parent to nodes in the network. Nodes having a relatively lower hop count may have a higher battery capacity than nodes having a higher hop count.

A system and method is provided for automatically reading meters, such as utility meters. A camera unit is attached to or otherwise associated with an existing meter. From time to time, either automatically, or upon wireless command, the camera unit takes an image of the meter's readings, and communicates wirelessly the image or image data, to a local area receiver. The images can be transmitted immediately, or stored for later transmission, depending on the network protocol. The camera unit is battery powered, and operates communication protocols that enable extended operational life. These protocols allow for the camera's radio and processor to be turned on only when necessary, and then for only brief periods of time. At most times, the camera is in a power-conserving sleep mode. Multiple camera units may be arranged to communicate meter image data to the local area receiver, either using asynchronous or synchronous processes. In this way, star, point-to-point, MESH and ring networking topologies are enabled. The meter image data is communicated from the receiver to a central office using a wide area connection, where the image data is used for determining the meter reading. In one example, the image may be included with a utility bill as confirmed evidence of the current meter reading.

Automated hierarchy classification in utility monitoring systems
An auto-learned hierarchy algorithm that learns the hierarchical layout of a power monitoring system. Historical power data from each meter is received and placed into a data table. The main is assumed to be at the top of the hierarchy and is designated as the reference. A check matrix is developed indicating whether a possible connection exists between each meter pair combination. A correlation coefficient matrix (CCM) is calculated based on the data table, and entries in which no connection is possible are zeroed. The column for the reference meter from the CCM is copied to a correlation reference array (CRA), and the meter having the highest correlation with the reference meter in the CRA is marked as connected to the reference meter in a connection table. That meter's power is subtracted from the data table and the procedure is repeated until all meters have been analyzed.

Topology identification in distribution network with limited measurements
A statistical technique is used to estimate the status of switching devices (such as circuit breakers, isolator switches and fuses) in distribution networks, using scares (i.e., limited or non-redundant) measurements. Using expected values of power consumption, and their variance, the confidence level of identifying the correct topology, or the current status of switching devices, is calculated using any given configuration of real time measurements. Different topologies are then compared in order to select the most likely topology at the prevailing time. The measurements are assumed as normally distributed random variables, and the maximum likelihood principle or a support vector machine is applied.

ActiveUS20100074176A1Reduce capital expenditureReduce operating costsEnergy efficient ICTTariff metering apparatusModem deviceOperational costs
A meshed networking of access points in a utility network provides a more efficient and cost effective arrangement for communicating data between meters and the utility by linking the access points of multiple subnetworks for purposes of communicating with the utility. As a result, each individual subnetwork is not required to directly communicate with the utility. For those access points that are relieved of the need to directly communicate with the utility, the communication mechanism, e.g., cellular modem, can be eliminated, or deactivated, to thereby reduce capital expenditures and / or operational costs. Additionally, links to a WAN can be selectively activated or disabled to provision bandwidth, for example, on demand, to react to changing conditions in the subnetworks.
