Abstract

This disclosure provides systems, method, and computer-readable media for operating a sensor network. The sensor network can include an array of sensor devices and gateways. The sensor devices can sense various conditions of an environment. The sensor devices can include temperature sensors, occupancy detectors, access sensors, motion sensors, tracking devices, etc. The sensor devices can also network and communicate with one another and the gateways in an ad hoc or mesh network. The environment can include different locations, such as warehouse, office building, a complex of buildings, cargo vehicles, containers or the like. The sensor network can be deployed for controlling power consumption, logistics, automated manufacturing, healthcare, intelligent buildings, and smart cities among many other implementations. The sensor devices can communicate sensed conditions and transmit data among each other without a predefined route. When a gateway receives the data, the data can be stored and analyzed at a different location.

Dependent claims

A method for operating a wireless sensor network comprising:

detecting a first condition at a first sensor device of the wireless sensor network;
transmitting, by the first sensor device, data regarding the first condition to the wireless sensor network;
detecting a second condition at a second sensor device of the wireless sensor network;
transmitting, by the second sensor device, data regarding the second condition to the wireless sensor network;
detecting a third condition at a third sensor device of the wireless sensor network, wherein the first sensor device, the second sensor device, and the third sensor device operate within a logical channel;
receiving, at the third sensor device, the first data and the second data;
determining, at the third sensor device, that the first data and the second data include a Private Area Network (PAN) ID associated with a grouping of sensors;
based on the determination, transmitting, by the third sensor device, the first data and the second data to the wireless sensor network;
detecting, by the third sensor device, a fourth sensor device;
determining, by the third sensor device, that the fourth sensor device operates in the logical channel;
based on the determination, accepting, by the third sensor device, the fourth sensor device into the wireless sensor network;
determining, by the third sensor device, that a software revision is available at the fourth sensor device;
receiving, by the third sensor device, the software revision from the fourth sensor device;
store, by the third sensor device, the software revision in flash memory for a duration of time:
transmitting, by the third sensor device, the software revision to the wireless sensor network after the duration of time;
transmitting the third data to the wireless sensor network;
receiving, at a gateway, the first data, the second data, and the third data;
and
storing, by the gateway, the first data, the second data, and the third data in a cloud-based storage memory.
