System for large area such as citywide telemetry data collection networks using a Mesh network of nodes including a backbone network of nodes, usually powered, and a plurality of sensor nodes, usually battery operated, in the Mesh network to communicate directly or indirectly through other such nodes, to one or more backbone nodes. Power consumption is held very low for the battery powered nodes by only requiring communication over very short distances, and by synchronizing operation of the system with a low duty cycle. The system may be self configuring, such as by using the Ad hoc On Demand Distance Vector routing protocol. Two way communication is possible for control and other purposes. Various applications and possible features are disclosed. |
