Network densification shrinks the footprint of base stations (BSs) and reduces the number of users associated with each BS, leading to an improved spatial frequency reuse and spectral efficiency, and thus, higher network capacity. However, the densification gain comes at the expense of higher handover rates and network control overhead. Hence, user’s mobility can diminish or even nullifies the foreseen densification gain. In this context, splitting the control plane ( C -plane) and user plane ( U -plane) is proposed as a potential solution to harvest densification gain with reduced cost in terms of handover rate and network control overhead. In this paper, we use stochastic geometry to develop a tractable mobility-aware model for a two-tier downlink cellular network with ultra-dense small cells and C -plane/ U -plane split architecture. The developed model is then used to quantify the effect of mobility on the foreseen densification gain with and without C -plane/ U -plane split. To this end, we shed light on the handover problem in dense cellular environments, show scenarios where the network fails to support certain mobility profiles, and obtain network design insights. dc.description.sponsorship This research was supported by a Discovery Grant funded by the Natural Sciences and Engineering Research Council of Canada. dc.publisher Institute of Electrical and Electronics Engineers (IEEE) dc.relation.url http://ieeexplore.ieee.org/document/7571101/ dc.subject stochastic geometry dc.subject 5G cellular networks dc.subject C-plane/U-plane split dc.subject lean carrier dc.subject network densification dc.subject phantom cells dc.subject handover dc.subject X2 interface handover dc.title Mobility-Aware Modeling and Analysis of Dense Cellular Networks With $C$ -Plane/ $U$ -Plane Split Architecture dc.type Article dc.contributor.department Computer, Electrical and Mathematical Sciences and Engineering (CEMSE) Division dc.contributor.department Electrical Engineering Program dc.identifier.journal IEEE Transactions on Communications dc.contributor.institution Department of Electrical Engineering and Computer Science, York University, Toronto, ON, Canada dc.identifier.arxivid 1607.06439 kaust.person Elsawy, Hesham kaust.person Alouini, Mohamed-Slim dc.date.published-online 2016-09-19 dc.date.published-print 2016-11
