Abstract:
A method and system are described for providing a wireless sensor network between a main node and a plurality of nodes, the nodes associated with sensors. The method and system define communications channels over which the main node communicates with the nodes based on a channel hopping scheme, and define at least one transfer channel that is dedicated to carrying transfer frames that are broadcast by the main node. The method and system configure non-acquired nodes that are not acquired to the network to enter a connection session by locating the at least one transfer channel to listen for a transfer message. The transfer message indicates a next communications channel that will become active. The method switches the non-acquired nodes to the next communications channel.
