Collaboration among two or more nodes that reduces multiple re-synchronization preambles and minimises energy consumption at each node

A method of communication that includes transmitting a communication signal having a 5 synchronization preamble from a first node and setting a local clock of at least one second node pursuant to the synchronization preamble to synchronize communications between the first and at least one second node. Data communications are subsequently exchanged between the first and at least one second node without additional preambles until a special switch point occurs and after the special switch point occurs. Information is transmitted that utilizes the period of reduced time-synchronization accuracy following data communication. Consequently energy constrained wireless sensor nodes no longer need to maintain clock synchronization suitable for information exchange during a sensing or actuation activity. The invention aims to provide collaboration among two or more transmitter/receiver nodes that reduces multiple re-synchronization preambles and minimizes energy consumption at each node and utilizes the residual clock synchronization period remaining after data communication is completed in the current communications frame.
