ABSTRACT

In this paper, Spectrum sharing technique among service providers to share the licensed spectrum of the licensed service providers for Heterogeneous wireless networks in a dynamic manner is proposed. Here, we could analyze and sense out the unoccupied bands, free bands, allocated bands by calculating the free spectrum metric. Hence, providing the opportunistic access to the licensed spectrum for unlicensed users ie other service providers try to access the available spectrum without causing interference to the primary users.
