Abstract

The work deals with the healing of the coverage hole identified in a location unaware network using fuzzy logic. The hole identification is done based on the Delaunay Triangulation method and the Empty circle concept. The main contribution here is that the healing of the coverage hole is done on a location unaware network based on the energy, angle and distance of the nodes involved in the healing process using the fuzzy rule set. Only the partial location information like the distance between the nodes is used. Redundant nodes are identified using the depth of angle formed between any two nodes. The boundary nodes of the hole along with their one hop neighbors take part in the healing process. This fastens the healing process with reduced energy consumption.
基于模糊逻辑的分布式无线传感器网络覆盖增强
利用模糊逻辑对位置不感知网络中识别出的覆盖洞进行修复。基于Delaunay三角剖分法和空圆概念进行孔识别。这里的主要贡献是,覆盖洞的修复是在一个不知道位置的网络上完成的,该网络基于愈合过程中涉及的节点的能量、角度和距离,使用模糊规则集。只使用部分位置信息,如节点之间的距离。使用任意两个节点之间形成的角度深度来识别冗余节点。洞的边界节点和它们的单跳邻居一起参与了愈合过程。这加快了愈合过程,减少了能量消耗。
