In this paper, the authors present best method for management of resource allocation to OFDMA (Orthogonal Frequency Division Multiplexing Access) based multi cells which are subjected to Inter Cell Interference (ICI) from adjacent cells. This paper implements allocation of resources that is frequency allocation and power allocation separately to provide quality of signals and compatible power to cell edge users. So to achieve frequency allocation low complexity heuristic algorithms are first proposed. To mitigate Inter Cell Interference (ICI) graph-based framework and fine Physical Resource Block (PRB) assignment are performed and hence improve the network performance.
