An Algorithm for Continuous Object Tracking in WSNs

Object tracking is among the imperative applications of WSNs. Tracking can be classified as single-target tracking, multiple-target tracking or continuous object tracking according to the type of targets. Contemporary researchers have mainly focused on single-target or multiple-target tracking, so that there has been little research on continuous object tracking. As a consequence, based on the protocols previously known in the field of continuous object tracking, we propose the Continuous Object Tracking Algorithm (COTA) which can adaptively schedule a sensor´s activity on the grounds of an object´s movement. Simulation has shown that the COTA protocol can steadily detect and track objects of any type-one object splitting into separated parts, several targets merged into one, or an object moving in 2-dimensional space.
