1. A wireless sensor communication module for operating in an ad-hoc sensor network having a plurality of nodes, the module comprising: a controller configured to receive power capability data representative of power capability of other wireless sensor communication modules in the sensor network and operable, in response thereto, to (i) determine a data transmission route through the sensor network based at least in part on the power capability data and (ii) supply transmission route data representative thereof; and a transceiver configured to receive sensor data and operable to modulate the sensor data with a radio frequency (RF) signal to thereby generate RF modulated sensor data, the transceiver additionally coupled to receive the transmission route data and operable, in response thereto, to transmit the RF modulated sensor data to a sensor network node in the determined transmission route.
