Wireless communication system with collision avoidance protocol |
摘要 |
A system of wireless infrastructure nodes are communicatively coupled to a number of internally powered leaf nodes. The leaf nodes may have sensors and/or actuators. A wireless leaf node transmits data to an infrastructure node at a time according to a duty cycle. When a collision occurs, the data is retransmitted until an acknowledgement is received from an infrastructure node. A change in a transmission protocol parameter, such as duty cycle/phase of sampling is initiated with such retransmissions. A decision to change the parameter is taken either by the wireless leaf node itself, or by an infrastructure node. Some of the leaf nodes can be transmit-only devices which repeat each data packet a number of times.
