Abstract
A method and apparatus for controlling energy expended by sensor network nodes is disclosed. The method comprises steps of acquiring energy information that is indicative of an energy status of a node in the network and adjusting at least one data transmission parameter according to the energy information. In a wireless network where the communication capacity and power energy of sensor nodes are limited, the invention provides the capability of efficiently utilizing the network resources, conserving power consumption of sensor nodes, and prolonging the life of the sensor network.
