LTE-WI-FI Aggregation in SDN Using Direct Concurrent Bandwidth Aggregation Model

Khaidem Bikramjit Meitei, Thounaojam Rupachandra Singh


In recent years, networks are loaded with heavy traffics due to increased online demands with diverse levels of QoSs (quality of services) required by customers resulting in complex challenges for network service operators. Significant increases in mobile data traffics using WiFi technologies use a concept called WiFi offloading which render only fifty percent of the traffic. These help in reducing network loads of cellular networks with optimal choices. Therefore, the aggregations of indoor WiFi technologies and cellular networks can help in strengthening networks with QoSs. In this study, LTEs (Long-Term Evolutions) and WiFi are aggregated using Direct - concurrent bandwidth’s aggregations are proposed and implemented. This work integrates and balances loads with with M-CORD (mobile-CORD) platforms using SDNs (software defined networks), NFVs (network function virtualizations), and cloud technologies for 5G environments. M-CORD platforms are made up of three main elements namely XOSs (service orchestrators), SDN controllers (ONOSs), and OpenStacks. M-primary CORD's features provision virtualized core network functions which are capable of facilitating the users in automatically customizing, monitoring, and controlling the resources of the network.
