Mobility management in multi-tier LiFi networks

Mobility management is an important part of the analysis and design ultra-dense LiFi networks. This paper thus presents a two-tier network analyses cross-tier handover rate between primary secondary cells. For different conditions semiangle at half illuminance cells, we propose three coverage models for Using stochastic geometry, closed-form expressions are derived rate, ping-pong sojourn time in terms received optical signal intensity, time-to-trigger, user mobility. The analytical validated with simulation results.
