Abstract

A network having at least one communication device having at least one sensor to process and manage sensor added information to adjust the state of the communication device or to adjust capacity limitations of the network. The sensor added information can be shared with other communication devices in the network to improve network capacity and add master devices to the network if needed to maximize the quality and efficiency of communications within the network.

Claims

1. A method of improving battery life of a wireless communication device, comprising:

sensing environmental conditions within a predetermined distance of the wireless communication device with a plurality of coupled sensors, each sensor of the plurality of sensors being selected from the group consisting of a crowd sensor, a range sensor, a moisture sensor and a sound sensor;

determining a usage pattern match based on the sensed environmental conditions; and

adjusting a power consumption level of the wireless communication device in accordance with the usage pattern match, wherein the wireless communication device switches from a stand-by power mode to an active mode when the sensed environmental conditions satisfy a predetermined condition and automatically transmits a predetermined message to a predetermined device after the predetermined condition is satisfied.
