An Analytical Model to Quantify the Effect of Handover and Cell Density on SINR in Emerging Cellular Networks

Existing SINR models are based on best server associations, which represent a network dominated by static users. During the handover (HO), users are not camped on the best-server, resulting in negative SINR. This is important because the emerging networks are likely to have a much higher HO rate due to higher base station density and an increased proportion of mobile devices. We derive a model that characterizes spatio-temporal downlink SINR as a function of BS density, user velocity, and HO delay duration.
