An Indoor Collaborative Coefficient-Triangle APIT Localization Algorithm
The Approximate Point-In-Triangulation (APIT) localization algorithm is a widely used indoor positioning technology due to its simplicity and low power consumption. However, in practice, In-to-Out misjudgments exist regularly in APIT, and a considerable amount of nodes cannot be positioned due to the low node density. To tackle this issue, a Collaborative Coefficient-triangle APIT Localization ...
متن کاملOn improving APIT algorithm for better localization in WSN
In Wireless Sensor Networks (WSNs), localization algorithms could be range-based or range-free. The Approximate Point in Triangle (APIT) is a range-free approach. We propose modification of the APIT algorithm and refer as modified-APIT. We select suitable triangles with appropriate distance between anchors to reduce PIT test errors (edge effect and non-uniform placement of neighbours) in APIT a...

متن کاملAn Improved Three-dimensional Localization Scheme based on APIT
In wireless sensor networks, location information is essential to its monitoring activities. In view of the “boundary effect” and lack of accuracy in APIT-3D, this paper proposes an improved three-dimensional localization scheme based on APIT named IAPIT-3D. In the scheme, the probability of misjudgment is reduced by adding the conditions of judgment. On one hand, the signal strength that all o...
