Network based offloading in LTE-WLAN Heterogeneous Networks

Abstract

To support the tremendously increasing data traffic volume in cellular networks, novel network architectures are getting evolved. Heterogeneous Network (HetNet) architecture is one such approach, where the serving nodes belonging to different Radio Access Technologies (RATs) coexist with the existing macro cell network, as an overlay. To leverage the full capacity of HetNet, efficient traffic handling schemes are required. With this consideration, we study and propose network based traffic offloading scheme and compare their performances on ns-3 simulator, for the Long Term Evolution (LTE) and Wireless Local Area Network (WLAN) RATs scenario in HetNet.
