通无线传感器网络是一种能量受限型网络,功率控制不仅能够提高网络层、MAC层、物理层的性能,同时还能提高能量效率。本文对无线传感器网络、博弈论和功率控制的意义做了简单的介绍,然后提出了一种功率控制的模型。 Passive wireless sensor network is a kind of energy limited network, power control can not only improve the network layer, MAC layer, physical layer performance, but also improve energy efficiency. This paper briefly introduces the significance of wireless sensor networks, game theory and power control, and then proposes a power control model.
