【摘要】 无线传感器网络是新兴网络,它采用无线通信技术,由微小的传感器组成,无线传感器网络节点具备感应能力、信息处理能力和无线通信能力,使无线传感器网络有广阔的应用前景,可广泛用于军事、环境、医疗保健、空间探索及各种商业应用。文中主要分析了无线传感器网络研究中的传感器定位问题,讨论了无线传感器网络在军事上的应用,展望了无线传感器网络的美好前景。 WSN自身定位系统和算法的性能直接影响其可用性,包括定位精度、规模、锚节点密度、节点密度、容错性和自适应性、功耗和代价7个性能指标,它们不仅是评价WSN自身定位系统和算法的标准,也是其设计和实现的优化目标。同时,这些性能指标是相互关联的,必须根据应用的具体需求做出权衡,以选择和设计合适的定位技术。本文中将就现有几种定位算法的优劣进行分析比较,并提出合理的改进和完善。 无线传感器网络的军事应用前景十分广阔。目前在军事上的具体应用包络智能尘埃(smart dust)、目标定位网络嵌入式系统技术战场应用实验和“灵巧传感器网络”(SSW:Smart Sensor Web)等等。更多还原

【Abstract】 Wireless Sensor Network is a burgeoning network, which is composed of tiny sensors with wireless communication technology. Nodes of WSN have influence, information handling and wireless communication abilities, making WSN have wide application foreground, including military, environment, medical treatment, space exploring and various business applications. In this paper, we mostly analyse sensor relocation in MSN, discuss its military application, and expect its fine foreground.Performance of itself relocation system and arithmetic of WSN will spang affect its usability. There are seven performance guide line: relocation precision, size, anchor nodes density, nodes density, fault-tolerant and itself adaptability, function expanding and cost. They are not only standards estimating itself relocation system and arithmetic of WSN, but optimizing target of design and implementation. At the same time, they are assiciated each other, so we should choose and design appropriate relocation technology basing on fact requirement of application. In this paper, we will compare several relocation arithmetic in existence, and advance reasonable amelioration advices.Military application foreground of WSN is very wide, at present, including smart dust, battlefield application experiment of target relocation network embed system technology, smart sensor web and so on.更多还原
