摘要:
无线传感器网络具有应用多样性特点,文中基于热点区域场景研究其拓扑控制问题。建立了无线传感器网络拓扑控制通用模型,进行了形式化描述和定义,分析了面向热点区域场景的拓扑控制目标和需求,提出了一种融合功率控制技术和分簇控制技术的混合式拓扑控制近似算法HTCA。HTCA能区分热点区域与非热点区域,在热点区域形成树结构并进行适当的剪接,而在非热点区域形成簇结构,该混合式拓扑结构能有效地降低全局能耗。仿真实验结果表明,HTCA能获得较优的拓扑结构,有效地延长了基于热点区域场景的无线传感器网络生命期
Abstract:
The application multiplicity is an important characteristic of wireless sensor networks.The topology control problem in hotspot scenes is studied by this paper.The topology control common model is constructed firstly,and the model is described and defined formally.The objective and requirement of topology control in hotspot scenes are analyzed,and a hybrid topology algorithm HTCA including power control and cluster control technologies is proposed.Hotspot scenes or non-hotspot scenes can be distinguished by HTCA.The tree-structure and proper cut engraftation are used to form topology in hotspot area,and the cluster-structure is used to form topology in non-hotspot area.The total energy consumption can be reduced by the hybrid structure.The simulation experiments suggest the HTCA can obtain well-constructed topology,which prolonged wireless sensor network lifetime in hotspot scenes effectively
