Because of the limited node battery power, energy optimization is important for the mobile nodes in wireless ad hoc networks. Controlled node mobility is an effective approach to reduce the communication energy consumption while the movement itself consumes energy. Based on cooperative communication (CC) model, the paper takes the energy consumption of node movement and their residual energy into account, and then proposes localized algorithms to direct nodes adapt their transmission power dynamically in mobile ad hoc networks. Compared with other algorithms by simulation, our mechanism shows its efficiency in improving the system lifetime.
