| 摘要 |
A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices. |

1. A method of routing communication traffic in a wireless sensor system, comprising:
measuring a signal strength of wireless signals received by a first wireless repeater unit from one or more wireless sensor units, one or more wireless base units, and one or more other wireless repeater units; wirelessly communicating, from the first wireless repeater unit, a first message indicative of the signal strengths measured by the first wireless repeater unit; updating, at a second wireless repeater unit and based on the first message, a first list comprising wireless sensor units with which the second wireless repeater unit can communicate; measuring a signal strength of wireless signals received by the second wireless repeater unit from one or more wireless sensor units, one or more wireless base units, and one or more other wireless repeater units; wirelessly communicating, from the second wireless repeater unit, a second message indicative of the signal strengths measured by the second wireless repeater unit; updating, at the first wireless repeater unit and based on the second message, a second list comprising wireless sensor units with which the first wireless repeater unit can communicate; and selecting routing paths for communication within the wireless sensor system based on the first list and the second list. |
