1. A method of routing communication traffic in a wireless sensor system, comprising:
- measuring the signal strength of wireless signals received by one or more wireless sensor units from a base unit and from one or more wireless repeater units;
measuring the signal strength of wireless signals received by one or more wireless repeater units from said base unit and from said one or more wireless sensor units;
transmitting the signal strength measurements from said one or more wireless sensor units and said one or more wireless repeater units to a computer; and
selecting routing paths for communications based on an evaluation by said computer of said signal strength measurements.

Abstract
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.
