Coexistence of LTE and WiFi heterogeneous networks via inter network coordination

Fast increases in mobile data demand and inherently limited RF spectrum motivate the use of dynamic spectrum sharing between different radio technologies such as WiFi and LTE, most notably in small cell (HetNet) scenarios. In our project, we propose an inter-network coordination architecture which facilitates dynamic spectrum management in the HetNets for interference mitigation and efficient spectrum utilization. We aim to model interference between LTE and WiFi networks through experimental evaluation using the ORBIT testbed and the USRP/GNU radio platform. We further propose to study the performance of cooperative algorithms between LTE and WiFi network involving logically centralized system level optimization for maximizing throughput subject to certain constraints.
