In the fifth generation communication system, millimeter wave (mmWave) networks will coexist with traditional micro (μWave) networks, which allows for higher data transmission rate and better user experience. this paper, we give a comprehensive framework of mathematical models analytical methods multi-tier mmWave μWave hybrid caching based on stochastic geometry. We propose an association strategy by assuming average biased-received power Rayleigh fading. Accordingly, using D-ball approximating blockage model expressions cell probability coverage are derived. Also, use successful delivery as performance metric to analyze existing placement strategies. Simulation results validate accuracy our conclusions.
