US Patent 8189479 Congestion control for wireless sensor networks

A system for congestion control for a wireless sensor network comprises a processor and a memory. The processor is configured to determine a level of congestion at one or more nodes and indicate an adjustment to network traffic in response to the level of congestion. The adjustment to the network traffic reduces the level of congestion at the one or more nodes. The memory is coupled to the processor and configured to provide instructions to the processor.
