Abstract
A method for forming a protocol structure for use in an ad hoc, distributed, scaleable wireless sensor node network which enables nodes to join the network autonomously without there being a designated, permanent central time reference and for enabling such nodes to synchronize timing with each other and with other nodes in the network. The method involves discovering the active channel changing sequence used by the network, synchronizing communications of a new node with the remainder of the nodes in the network and scanning communications channels to detect merging clusters of nodes.
