Abstract
Wireless ad hoc networks operation is constrained by energy consumption of every network nodes. To this end, this paper, based on Geographical Adaptive Fidelity (GAF) topology management protocol [1], analyzes the energy consumption in a rectangular ad-hoc wireless network. Three GAF models for energy efficiency are introduced and discussed: equal-grid, adjustable-grid and genetic algorithm models. In the equal and adjustable-grid models, the optimal transmission range corresponding to the minimum energy consumption has been derived, meanwhile the third model is based on on a genetic algorithm introduced to save energy consumption in rectangular ad hoc networks. Results based on numerical analysis show that the genetic-algorithm model outperforms the equal and adjustablegrid models in term of energy consumption. Finally, we simulate a network model in which nodes can transmit at different transmission ranges, where the GAF models including the genetic algorithm model show better saving in energy consumption than those GAF models based on static transmission range.
