Introduction
============

Over the last two decades models with extra spatial dimensions [@arkani; @horava; @RS; @kaloper; @cohen; @burgess; @chodos] have been increasingly playing a central role in physics beyond standard model of particle [@rattazzi] and Cosmology [@marteens; @inflation; @bouncing]. Such higher dimensional scenarios occur naturally in string theory. Depending on different possible compactification schemes for the extra dimensions, a large number of models have been constructed. In all these models, our visible universe is identified as one of the 3-branes embedded within a higher dimensional spacetime and is described through a low energy effective theory on the brane carrying the signatures of extra dimensions [@kanno; @shiromizu; @sumanta].\
Among various extra dimensional models proposed over last several years, warped extra dimensional model pioneered by Randall and Sundrum (RS) [@RS] earned a special attention since it resolves the gauge hierarchy problem without introducing any intermediate scale (between Planck and TeV) in the theory. Subsequently different variants of warped geometry model and the issue of modulus (also
