Within the framework of open quantum systems, we analytically study the dynamics of a V-type three-level atom interacting with a dissipative reservoir in the presence of N−1 auxiliary and similar atoms. We demonstrate how the initial coherence of the V-type three-level atom can be protected by inserting more auxiliary atoms into the reservoir and manipulating the spontaneously generated interference between two possible transitions of the atoms. Furthermore, we show that as the number of auxiliary atoms becomes sufficiently large, the initial coherence of the considered V-type three-level atom is preserved to a great extent in the dissipative reservoir.
