Abstract
In wireless sensor networks
in order to reduce the height of clusting tree
it is necessay to design an algorithm which can limit the least hops from nodes to the base-station.The energy-aware topology control protocol based on gradient(ETBG)algorithm is introduced and its maintenance and updating algorithm in the light of topology changes caused by new nodes join or nodes death is proposed.The simulation results demonstrated that they are effective.
