Impact of Wall Blockage on LOS User Association Strategy in Indoor Small Cell Networks

Interior wall blockage affects the performance of indoor cellular networks but has not been sufficiently studied. In this paper, by incorporating the attenuation caused by wall blockages into to the path loss model, we develop a tractable approach to analyse the performance of indoor cellular networks under the influence of interior wall blockages. Then, the proposed analytical approach is applied to study the downlink coverage probability of line-of-sight (LOS) user association strategy. The analytical results are validated by Monte Carlo simulations in comparison with those obtained under the existing wall blockage model that assumes impenetrable walls.
