In this work, a fair user association scheme is proposed for heterogeneous networks aiming to enhance physical layer security (PLS). More specifically, the user association problem is formulated as a Nash bargaining problem (NBS) with the objective of maximizing sum secrecy rate. Firstly, we develop a two player bargaining scheme for two base stations (BSs) in order to bargain user association for enhancing secrecy rate and then it is extended to multi-player bargaining scheme using hungarian algorithm. Simulation results are presented for proposed scheme and compared with SINR based association to show the effectiveness of our algorithm.
