A novel cell-selection optimization handover for long-term evolution (LTE) macrocellusing fuzzy TOPSIS

摘要: Optimal cell-selection scheme that allows a roaming UE to reconnect the most suitable cell while maintaining its quality of service (QoS) requirements.Very low ping-pong handover ratio and failure ratio.Higher throughput gain.Considering uplink downlink conditions make reliable radio link connection.A comprehensive investigation proposed at varying speeds is demonstrating robustness. To satisfy demand for higher data rate service, dense long-term evolution (LTE) cells environment required. This imposes big challenge network when it comes performing (HO). Cell selection has an important influence on performance, achieve seamless handover. Although successful accomplished, might be wrong selected not optimal one in terms signal bandwidth. may cause significant interference with other cells, (HOF), or (HOPP), consequently degrading throughput. address this issue, we propose multiple-criteria decision-making method. In method, use integrated fuzzy technique order preference by using similarity ideal solution (TOPSIS) S-criterion, availability resource blocks (RBs), signal-to-interference-plus-noise ratio. The conventional LTE based which inadequate since only relies quality. A novel method called (FMCCS) paper. FMCCS considers RBs utilization user equipment condition addition S-criterion. System analysis demonstrates managed reduce significantly. improvement stems from highly leads increased simulation results show outperforms (CSS) methods.
