The Most nodes of ad-hoc wireless networks are battery-powered, therefore limit of energy is one of the critical constraints of ad-hoc wireless networks' development. This paper analyzes a real two dimensional ad-hoc network that achieves energy-efficiency by optimizing the node radio range based on the Geographical Adaptive Fidelity (GAF) topology management protocol. This paper derives the optimal transmission range of nodes and analyzes both static and dynamic traffic scenarios in both equal-cell and adjustable-cell 2-D GAF models, where the results show that the adjustable-cell model saves 62.6% energy in comparison to the minimum energy consumption of equal-cell model.
