Energy-Aware Dynamic Topology Control Algorithm for Wireless Ad Hoc Networks
Topology control via per-node transmission power adjustment has been shown effective in extending network lifetime. However, most of existing algorithms construct static topologies which fail to consider the residual energy of network nodes, thus in fact they can not balance energy consumption efficiently. To address this problem, a lightweight distributed topology control algorithm EDTC (Energy-aware Dynamic Topology Control) is proposed in this paper. Based on the link metric reflecting both the energy consumption rates and residual energy levels at the two end nodes, EDTC generates a dynamic network topology that changes with the variation of node energy.
