indoor communications as the extension of cellular networks
for enhancing coverage performance. Because femtocells have
small coverage radius, typically from 15 to 30 meters, a
femtocell user (FU) walking at low speed can still make
several femtocell-to-femtocell handovers during its connection.
When performing a femtocell-to-femtocell handover, femtocell
selection used to select the target handover femtocell has to
be able not only to reduce unnecessary handovers and but
also to support FU’s quality of service (QoS). In the paper,
we propose a femtocell selection scheme for femtocell-tofemtocell handover, named Mobility Prediction and Capacity
Estimation based scheme (MPCE-based scheme), which has
the advantages of the mobility prediction and femtocell’s
available capacity estimation methods. Performance results
obtained by computer simulation show that the proposed
MPCE-based scheme can reduce unnecessary femtocell-tofemtocell handovers, maintain low data delay and improve
the throughput of femtocell users.Dong Hoang Nhuddonghoang93@gmail.comHoang Nguyen Namhoangnn@vnu.edu.vnMinh Hoang Tronghoangtrongminh@yahoo.comTakahiko Sabasaba@cs.it-chiba.ac.jp
