A Groundbreaking Hexagonal Network Design for Smooth LTE-Unlicensed and WLAN Coexistence

Tremendous demand for mobile data at recent years is solved from new innovations of coexistence among network operators. Extending long term evolution (LTE) over unlicensed band (i.e., LTE-U) with the coexistence of Wireless Local Area Network (WLAN) which carries more complex interaction between two different technologies that leads degradation of throughput and data rates. Missing of coordination in LTE-U and WLAN causes higher levels of co-channel interference. To address this unfair coexistence problem, we propose a Hexagonal Network Design (HED) for achieving higher throughput during coexistence of LTE-U and WLAN in unlicensed band. 120° sectoring of cellular network minimizes co-channel interference and employment of spectrum agent in HED is likely to support accurate spectrum decisions. Validate Channel before Communication (VCC) and chose optimal user equipment using hybrid Particle Swarm Optimization with Fuzzy Logic (PSO-FL) algorithm. Clustering using REpresentatives (CURE) algorithm is involved to manage all the participating user equipment in HED. Evaluation result of this work is simulated from Ns-3, demonstrates that HED can improve throughput while providing coexistence between LTEU and WLAN.
