Abstract: In this paper, an integration architecture based on loose coupling concept between WiFi and LTE heterogeneous networks (HetNet) was proposed. The ultimate objective is to investigate the feasibility and the practicality of the design through investigating the performance measures for different applications in the network. As well, a functionality of the load balancing was deployed in the architecture in order to prove that the architecture is flexible and can be opened to any further functionality. The architecture was built and simulated using riverbed network simulator. It was proved that the architecture is working appropriately, and the connectivity of the different technologies were demonstrated by applications communication with each other’s in the architecture. Along with, different existing load balancer algorithms were tested on the architecture and numerical results were obtained demonstrating that algorithm is better.
