Optimized Local Broadcast

It is standard for meter reading systems to execute a broadcast command from every point of origin in their system. If they have N points from which to broadcast from, they utilize all N points during the time required to execute the broadcast. This description will discuss a more efficient broadcast method and draw a distinction between the two that illustrates an improvement in network efficiency. By optimizing the broadcast to use the minimum points of origin (Collectors), the master station will reduce the amount of resources and network time required to broadcast commands.

In the master station, broadcast commands will generally be created for a group of endpoints, although a system wide flood broadcast will be supported. The group information indicates the endpoints to be targeted by the broadcast. The group information will consist of area, feeder, and demand response program. Individual endpoints will have been previously configured for a group. The inputs provided to the master station are the command to be broadcasted and the targeted group.

Current registration relationships between endpoints and collectors are managed in the master station database. This information is updated for registered endpoints each time the system calls a collector. Upon receiving the required broadcast inputs, master station will construct a list of collectors from which a broadcast request will be issued such that the maximum number of targeted endpoints receive the broadcasted command. However, only collectors that have targeted endpoints registered will participate in the broadcast. Unregistered endpoints will not act on the command even...
