Abstract—Within the foreseeable future, the growing number of mobile devices, and their diversity, will challenge the current network architecture. Furthermore, users expect higher data rates, lower latency, lower packet drop rates, etc. in future wireless networks. Development of Ultra Dense Networks (UDN), which have been considered one of the promising enablers of future wireless network deployment, is facing multiple significant hurdles, including interference, mobility, and cost. In this paper, we review existing research efforts toward addressing those challenges and present future avenues for research. To be specific, we first develop a taxonomy to review and describe existing research efforts, and then devote our focus to the areas of intercell interference, handover performance, and energy efficiency as the key techniques to addressing those most pressing challenges discussed. Finally, we present future research directions, including emergent Internet-of-Things (IoT) applications, security and privacy, modeling and realistic simulations, and relevant techniques. (i.e., Massive multiple input multiple output (Massive MIMO), millimeter Wave (mmWave)).
