Abstract

The environmental test chamber for wireless sensor networks includes a structural enclosure having peripheral walls. A dynamic topology builder is a hanging mechanism disposed in a ceiling portion of the structure and is used to suspend the wireless devices below the ceiling portion via a cable. A weather conditioning machine simulating environmental conditions is disposed in at least one of peripheral walls. A controller sends commands to control the suspension height of the wireless units and to control environmental parameters of the weather conditioning machine. This allows the test chamber to test the communication and networking aspects of the wireless sensor network devices in different environmental conditions, such as sand storms and different temperatures, and humidity levels, within a 3-D topology specified by the controller.

Dependent claims

An environmental test chamber for wireless sensor networks, comprising:

a chamber defined by peripheral walls, the chamber having a ceiling;
an intertwined net disposed in the ceiling of the chamber, the intertwined net defining nodes configured in an X-Y plan;
at least one cable;
a motor disposed in at least one of the nodes, the motor selectively paying out and reeling in the at least one cable to lower and raise the cable in a Z-axis direction, the at least one cable being adapted for suspending at least one energized wireless device therefrom inside the chamber;
a weather conditioner disposed in at least one of the peripheral walls, the weather conditioner having means for simulating user-selectable weather condition inside the chamber;
and
a controller connected to the motor and to the weather conditioner, the controller being configured for sending commands to the motor responsive to user input to raise and lower the suspended energized wireless device and configured for sending commands to the weather conditioner responsive to user input to simulate selected weather conditions inside the chamber.
