考虑到无线传感器网络的特点,控制机制必须具有可扩展性、自适应性、鲁棒性、全分布性和自组织性。在本文中,我们专注于拓扑控制的周期性数据收集,这当然是一个典型的应用无线传感器网络。我们提出了一种新的机制的基础上的生物自组织机制,即反应扩散模型,以组织的最佳拓扑结构的自组织和自治的方式。反应扩散模型是研究鱼类和哺乳动物体表图案生成的数学模型。节点通过相邻节点之间的相互作用产生空间分布的光斑图案。选择激活剂浓度达到峰值的节点作为簇头,其他节点根据激活剂浓度的梯度向簇头发送数据。仿真实验表明,有组织的拓扑实现了与优化得到的最佳拓扑一样小的能耗和时延。
Considering characteristics of wireless sensor networks,control mechanisms must be scalable, adaptive, robust, fully distributed, and self-organizing. In this paper, we focus on topology control for periodic data gathering, which certainly is one of typical applications of WSNs. We propose a novel mechanism based on a biological self-organization mechanism, that is, a reaction-diffusion model, to organize the best topology in a self-organizing and autonomous way. A reaction-diffusion model is a mathematical model for pattern generation on the surface of body of fishes and mammals. Nodes generate spatially distributed spot patterns through mutual interaction among neighboring nodes. The node which has a peak of activator concentration is elected as cluster head, and other nodes send their data following the gradient of activator concentration to the cluster head. Through simulation experiments, it is shown that organized topology accomplishes as small energy consumption and delay as the best topology optimally derived.
