摘要: 在含有移动节点的混合无线传感器网络中,为优化网络覆盖性能,基于包容式体系结构的思想,提出了一种基于行为的移动节点控制策略。设计了移动节点的5种基本行为,分别是停止、漫游、避让固定传感器节点、避让移动传感器节点以及奔向网络覆盖盲区,各行为之间采用竞争与抑制机制进行行为选择。通过仿真实验验证了算法的有效性。

Abstract: For hybrid wireless sensor networks with mobile nodes, to optimize the coverage performance, based on the subsumption architecture, a kind of behavior-based control strategy for mobile nodes was proposed. Five basic behaviors were designed, i.e., Stop, Wander, Avoid_Static_Node, Avoid_Mobile_Node and Move_To_Coverage_Hole. And the competition and suppression mechanism for choice of behavior were used. Simulation results show the validity of the algorithm.
