摘要

The use of directional communication can result in higher performance of ad hoc networks in terms of throughput and delay. To exploit these advantages, we propose a system architecture that applies k air interfaces on each node. Each interface is equipped with a directional antenna. However, the energy consumption of such a system would be too high intuitionally. Power management is required that switches off the air interfaces if they are not needed. Hence, we design a detailed energy model for the system and a MAC protocol based on CSMA/CA with extensions for parallel directional communication, radiation power control and air interface power management. We verify and evaluate our implementation in a simulation environment. Our results show that the proposed system can achieve an energy efficiency comparable to a single antenna system while increasing the throughput and time efficiency of the resulting ad hoc network by a factor of 2-3.
