摘要:

研究了无线传感器网络中的数据汇聚节点放置问题. 通过将无限的搜索空间划分为有限的"通讯交集",在量级上降低了问题的复杂度. 基于这样的理念,建立了基于网格的线性优化模型,并由仿真试验验证了此方案的有效性.

关键词: 无线传感器网络, 通讯交集, 汇聚节点, 网络生命周期

Abstract:

The sink node deployment problem in wireless sensor networks is studied. By dividing infinite search space into a limited number of so-called "communication intersections", computational complexity has been significantly reduced. A grid-based linear programming is formulated and numerical results show the effectivity of the proposed approach.

Key words: wireless sensor networks, communication intersections, sink node, network lifetime
