中文摘要: 攻击无线传感器网络(WSNs)的基站(sink)可能使整个网络无效. 因此, 某些情况下隐藏sink 物理位置显得非常必要. 鉴于以往研究都是假定了一个弱对手模型. 通过线性规划(LP)框架, 提出了两种 sink 隐藏方法: 假sink(FS)方法和平衡流量(BF)方法. 通过仿真实验, 分析并比较了两种方法对网络寿命的影响. 研究结果表明:(1)保护sink 不可观测对网络寿命的影响相当大; (2)在大型网络中, BF 的网络寿命优于FS.
Abstract:An attack to the base station (sink) in wireless sensor networks (WSNs) may make the entire network to be invalid, Therefore, it is very necessary to conceal the physical location of the sink in certain circumstances. In view of previous studies has all assumed a weak adversary model. Through a Linear Programming (LP) framework we present two different sink hiding methods: fake sinks (FS) method and balanced flows (BF) method. By simulation we analyzed and compared two methods with respect to their impact on network lifetime. Our results show: (1) The impact of preserving sink unobservability on network lifetime is considerable; (2) Network lifetime with BF is better than with FS in large networks.
