Mesh network applied to fixed establishment with movable items therein

Abstract

The invention relates to a mesh network applied to fixed establishment with movable items therein. Mesh node modules are associated with movable and fixed items in a building such as a grocery store or factory floor to maintain a database of the locations of those items as they are processed through the establishment. The items form a mesh network and relay location information through access points, when in range, to control / monitoring computers.

Description

technical field [0001] The present invention relates generally to mesh networks applied to fixed locations with movable items therein. Background technique [0002] A mesh network is a computer ecosystem characterized by its persistence, self-organization, and scalability. Each mesh node relays network data flowing to that node, and the nodes cooperate to properly distribute data in the network. Although mesh networks may use gateways to connect to wide area networks such as the Internet, in general mesh networks are relatively short-range networks, ie, with node-to-node link distances of 250 meters or less. [0003] Since mesh networks are usually wireless, they are ad hoc, meaning nodes can easily join and leave the network. As just one example, a mesh network can be spontaneously organized by wireless computing devices using Zigbee to establish nodes. Other example non-limiting mesh networking protocols / systems may be based on Wi-Fi IEEE802.11p, IEEE802.11s, WAVEIEEE16...
