Traffic load control in a mesh network
First Claim
1. Methodology for a network with self-adjusting traffic load management, comprising:
- establishing a network including a plurality of node devices, at least some of which node devices provide communications at least in an uplink direction between others of the node devices and a central facility;
monitoring and calculating traffic density of communications in an uplink direction with reference to each respective node device; and
controlling timing of transmissions of communications in an uplink direction of each respective node device based on its traffic density calculation, so that such traffic density calculation remains below a predetermined network limit.

Abstract
The present technology relates to protocols relative to utility meters associated with an open operational framework. More particularly, the present subject matter relates to protocol subject matter for advanced metering infrastructure, adaptable to various international standards, while economically supporting a 2-way mesh network solution in a wireless environment, such as for operating in a residential electricity meter field. The present subject matter supports meters within an ANSI standard C12.22/C12.19 system while economically supporting a 2-way mesh network solution in a wireless environment, such as for operating in a residential electricity meter field, all to permit cell-based adaptive insertion of C12.22 meters within an open framework. Cell isolation is provided through quasi-orthogonal sequences in a frequency hopping network. Additional features relate to apparatus and methodology subject matters concerning Traffic Load Control in a Mesh Network.
