18455 现代建筑设计趋于多样化，内部结构和功能越来越复杂，而传统疏散系统逃生指示方向固定、人员疏散时间较长，火灾发生时，不能够及时改变指示方向，易将逃生人员导向危险区域，威胁被困人员生命安全。 With an increasing diversity in modern architectural design, the inner structure of buildings is muchmore complex than before, which makes the traditional fire emergency escape indication system fail to providepeople with real-time instructions because of its inflexibility of changing direction. These failures always lead people to dangerous areas during a fire emergency, which is actual a threaten to people in buildings.
18456 该文提出了一种Dijkstra-ACO混合路径动态规划算法，在Dijkstra算法获得全局最优路径的基础上再采用蚁群优化(ACO)算法对每个节点进一步优化以获取最优路径，并节省算法运行时间。 A combined algorithm to find a path dynamically during a fire emergency based on Dijkstra and Ant Colony Optimization (ACO) algorithm is presented in this article. This new algorithm shortens the programming time by getting a globally optimal path based on Dijkstra algorithm and operates every single point with ACO algorithm in sequence to get a best path.
18457 通过实验仿真验证了混合算法的有效性，能够根据起火点动态规划疏散路径，及时调整疏散指示方向，为火场中人员疏散逃生赢得宝贵时间。 The combined algorithm is tested by a simulation, in which it isproved effective in adjusting evacuation path depending on the point of ignition. The changeable real-timeindication will extend the escaping time with people in a burning building, which is quite precious for savinglives.
18458 节点位置保护对于海洋无线传感器网络(MWSNs)至关重要，尤其是对于无人值守的环境。 Source node location protection is critical to the Marine Wireless Sensor Networks (MWSNs),especially for unattended environment.
18459 然而，由于大多数静态部署，传感器的能量、存储和通信能力的限制，MWSNs容易受到各种位置(和衍生)攻击的影响。 However, due to most of the static deployment and the limitations inenergy, storage and communication capabilities of the sensors, MWSNs are vulnerable to various location (andderivative) attacks.
18460 该文从攻击和防御两个方面研究节点位置隐私保护问题。 In this work, the node location privacy protection issues are studied from both aspects of attacks and defenses.
18461 首先，针对两种重要节点(包括基站和源节点)提出了一种新的二相定位攻击，它可以在少量的本地无线传输监视中找到基站节点，反向跟踪源节点的位置。 First, a new two-phase location attack is proposed for two important types of nodes(including base station and source node). It can locate a base station node within few amounts of local wirelesstransmission monitoring, and then reversely traces the location of the source node.
18462 与现有方法不同，提出的攻击根据传输方向确定节点位置，从而突破现有的防御。 Different from existing methods, the proposed attack determines the node location based on the transmission direction, which can break through existing defenses.
18463 然后，为了抵御这种攻击，该文设计了一种基于Hilbert填充曲线的传感器网络路由节点位置隐私保护方法(HLPS)。 Then, to defend against such attack, a Hilbert-filling-curve-based Location-privacy Protection Scheme (HLPS) is designed for MWSNs.
18464 攻防理论分析与对抗实验表明，该方法能够保护目标节点的位置隐私，具有较小的通信和计算开销。 The theory analysis and confrontation experimentof attack and defense show that the proposed scheme owns capable of protecting the location privacy of thetarget node with moderate communication and computation overhead.
