Localization

The localization approach is proposed for a network of mobile sensor nodes floating in a river [1, 2]. The sensor nodes communicate only with their neighbor nodes. The collected information through this local communication is used to estimate the locations of the events without any GPS receivers at the sensor nodes. To model the movements of the sensor nodes, a realistic meandering current mobility model [3] is employed. The motion of the sensor nodes in this model follows the advection of the fluid parcels, which is modeled as a combination of a central streamline with a meandering motion around the surface. To the best of our knowledge, this is the first example of using meandering current mobility model with random surface motion for a WSAN operating on the surface of a river.
