Interference Avoidance Technique for Wireless Networks Used in Critical Applications |
| 摘要 |
An apparatus is provided that uses the steps of providing a plurality of wireless sensor devices coupled to a controller in a security system configured into a wireless network where at least one is a child sensor device that communicates with the controller through at least first and second parent sensor devices, the child sensor device measuring an environmental parameter within the secured area and transmitting a message to the controller through the at least two parents, the message is transmitted during a first time period and on a first frequency to the first parent and a copy is transmitted during a second time period and on a second frequency to the second parent wherein the first and second times and first and second frequencies are all different and wherein the first and second time periods are directly adjacent to one another in time. |

1. A method comprising:
providing a plurality of wireless sensor devices coupled to a controller in a security system, the plurality of wireless sensor devices configured into a wireless network that protects a secured area where at least one of the wireless sensor devices further comprise a child sensor device that communicates with the controller through at least first and second parent sensor devices, wherein the plurality of wireless sensors may each further comprise a sensor, a repeater or an output device; the child sensor device measuring an environmental parameter within the secured area; and the child sensor device transmitting a message including at least the measured environmental parameter to the controller through each of the at least two parents, the message is transmitted during a first time period and on a first frequency to the first parent and a copy of the message is transmitted during a second time period and on a second frequency to the second parent wherein the first and second time periods and first and second frequencies are all different and wherein the first and second time periods are directly adjacent to one another in time. |
