METHOD AND APPARATUS FOR CONTROLLING ENERGY CONSUMPTION OF SENSOR NETWORK NODES

摘要

Present invention is to provide a method and apparatus for controlling energy- expanding of sensor network nodes, wherein the method comprises steps of : acquiring energy information, said energy information being indicative of an energy status of a node in the network; and adjusting at least one data transmission parameter accordingly based on the energy information. The at least one data transmission parameter may be the retransmission timeout and/or retransmission timer. With present invention, on the premise that the communication capacity and power energy of sensor nodes are limited in a wireless sensor network, it is capable of efficiently utilize the network resource, save the power consumption of sensor node, and prolong the whole life of sensor network.
