A Method to Incorporate Floor Plan Constraints into Indoor Location Tracking: A Voronoi Approach

Table 3

Heuristic parameter values that optimize “Dublin 87pts forward” results.

Parameter	Value	Description
	10.66	Constant term for RSSI variance
	0.194	Distance at which mesh edge is as strong as tie to measurements
	0.166	RSSI variance term per meter separation from real data point
	1.050	Weight for neighbor variances in RSSI variance
	10.40	Distance penalty for edges that cross room boundaries
	2.107	Refined Delaunay triangles must fit in circle of this radius
	0.411	Don’t allow Delaunay edge across a wall < this from a vertex
	−95	Fingerprint RSSI at artificial corner points

All distances are in meters.
