Energy efficiency for rectangular ad-hoc wireless networks
Wei Feng, Hamada Alshaer, Jaafar M. H. Elmirghani · 2009
Most nodes of ad-hoc wireless networks are battery-powered, therefore the energy capacity limit is one of the critical constraints of ad-hoc wireless networks' development. This paper evaluates a rectangular network model that achieves energy efficiency by optimizing the node radio range based on the Geographical Adaptive Fidelity (GAF) topology management protocol [1]. For the first time we derive the optimal transmission range in a new adjustable-grid model and analyze both static and dynamic traffic scenarios in both equal-grid and adjustable-grid rectangular GAF models, where the results show that the adjustable-grid model is more energy efficient.
