基于激素调节的传感器网络覆盖算法*

人体内环境的平衡是由各种激素的相互作用来协同调节和控制的，根据抽象出的激素作用机理，提出了一种基于激素调节的传感器网络覆盖算法(HCA)，该算法是完全分布式的，节能的传感器网络覆盖算法，算法中节点状态(sleep或active)的选择通过激素来调节和控制，即通过给邻居节点发送激活荷尔蒙或抑制荷尔蒙来刺激或抑制邻居节点成为active状态。仿真实验表明，与DELIC和UC算法相比，该算法既能有效地保证区域覆盖，又可以使得active状态的节点尽可能少。

Hormone based coverage algorithm in wireless sensor networks

Hormones play a significant role in modulates the balance of the internal environment. This paper proposed a hormone based coverage algorithm (HCA) in wireless sensor networks, which was distributed and energy-saving. In the proposed algorithm, a sensor node would transform its state to sleep or active when it received inhibit hormone (IH) or active hormone (AH). Comparative experiment shows that the proposed algorithm not only grant the effective coverage of wireless sensor network but also has less active sensor nodes compared with DELIC and UC.
