Information is generated in certain nodes and needs to reach a set of designated gateway nodes.
Each node may adjust its power within a certain range that determines the set of possible one hop away neighbors. Traffic forwarding through multiple hops is employed when the intended destination is not within immediate reach. The nodes have limited initial amounts of energy that is consumed in different rates depending on the power level and the intended receiver. Energy conserving routing in wireless ad-hoc networks.
