摘要 为保证网络的覆盖功能,提出了一种在固定传感器节点中加入具有运动能力的移动节点的混合无线传感器网络模型。在此基础上,基于人工势场法的思想,提出了一种基于局部虚拟力的无线传感器网络覆盖增强算法,构造了节点与节点、移动节点与目标区域边界之间的相互作用力,并基于运动图式理论来共同控制移动节点的运动。为避免移动节点陷入局部极大覆盖陷阱,还引入了随机扰动作用力。最后通过仿真实验验证了算法的有效性。 To guarantee good coverage performance of wireless sensor networks, a kind of hybrid network model was proposed, which introduced mobile nodes having mobility into the network consists of static nodes. And then, inspired by Artificial Potential Field, a local virtual force-based wireless sensor network coverage-enhancing algorithm was addressed. Virtual force was constructed by interaction force among different nodes, and interaction force between mobile nodes and the border of the target area, so as to guide the motion of mobile nodes using motor schema theory. To avoid local maximum coverage trap, the random force was introduced. Simulation results have shown the validity of the algorithm.
