Abstract

In this paper we propose a new way to control power allocations for vehicle transmissions in vehicular networks (VANET). Our proposal is based on usage of infrastructure nodes along the roads that can be equipped with special hardware advertising information about distance between successive vehicles on the road. We analyze our system exploring the trade-off between density of infrastructure nodes and accuracy of power allocation. Our numerical results demonstrate that the proposed approach may improve accuracy of power allocation. Finally, the proposed approach does not necessarily replaces those proposed to date but may coexist with them and improve their performance.
