Positioning of Node Using Plane Projection onto Convex Sets
Paper in proceedings, 2010
We deal with positioning of node in wireless sensor
network (WSN) using received signal strength (RSS) when there
is no priori knowledge about path-loss exponent and transmission
power. Since the RSS decreases on the average with distance, it
carries some information about the distance to an unknown node.
By ordering the RSS's, we conclude that there are some convex
sets where the position of the unknown node can be found in
the intersection of them. We introduce a plane projection onto
convex sets (PPOCS) approach to solve the positioning problem.
Simulation results show good performance for the new methods
compared to other reduced complexity algorithms.
