Wireless Network With Multiple Paths Between Nodes

摘要

A wireless communications system includes both a primary communications path wherein a gateway can communicate with each member of a plurality of ambient condition detectors, and a secondary back-up path available in the event of a failure on part of the primary path. Required power for the network can be minimized by path selection.

1. A method comprising:
establishing a selected distance parameter; assigning an initial slot address to the gateway; and establishing a primary path by determining those nodes closest to the gateway according to the devices' relative distances and installation site's environmental peculiarities, and assigning an incremented level value to each such current node, for each current node with an incremented level with a value of one greater than the gateway's one, search for the two closest unassigned nodes using the same distance evaluation criteria and connect them to the current node and then assign those nodes a level one greater than that of the current nodes, and repeating the process till all nodes are assigned a level value.
