Abstract

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 also consumes energy. Based on cooperative communication (CC) model, this paper takes the energy consumption of node movement and their individual residual energy into account, and then proposes localized algorithms for directing mobile node mobility and adapting their transmission power dynamically in mobile ad hoc networks. Compared with other algorithms by simulation, our mechanism named DEEF shows its efficiency in improving the system lifetime.
