Cross-Layer Power Control of Ad Hoc Network Based on Ant Colony Optimization

This paper studies the power control mechanism of MAC layer and network layer of ad hoc network and proposes a cross-layer power control model which absorbs ant colony optimization in it. After getting the minimum sending power between each two nodes, the virtual central node can find network topology by Ant Colony Optimization (ACO) in network layer, then each pair of communication nodes adaptively adjust the current optimal sending power according to the exchange of information between nodes in link layer to realize the cross-layer power control. The simulation results show that in ad hoc network, the power control mechanism can quickly find the optimal path and effective reduce the energy and power consumption of nodes.
