Software-Defined networking (SDN) dynamically and efficiently manage resources to provision diverse services leveraging controller intelligence and programmability. SDN enable the network systems to orchestrate and estimate the available resources and dynamically adapt to the environment for a maximize resource utilization.

Deep learning (DL) is becoming a successful way to boost the SDN controller intelligence as a promising machine learning solution. Machine learning and Artificial intelligence (AI) techniques provide effectiveness for adaptation in network communication. The controller trained with AI and Machine learning sophisticated algorithms can enhance the provision of End-to-End (E2E) Services, Security, and resources management.

  • Mobility Management in Small Cell Cluster of Cellular Network
  • Abstract The installation of small cells in a 5G network extends the maximum coverage and provides high availability. However, this approach increases the handover overhead in the Core Network (CN) due to frequent handoffs. The variation of user density and movement inside a region of small cells also increases the handover overhead in CN. However, the present 5G system cannot reduce the handover overhead in CN under such circumstances because it relies on a traditionally rigid and complex hierarchical sequence for a handover procedure. Recently, Not Only Stack (NO Stack) architecture has been introduced for Radio Access Network (RAN) to reduce… More

  • Q-Learning Based Routing Protocol for Congestion Avoidance
  • Abstract The end-to-end delay in a wired network is strongly dependent on congestion on intermediate nodes. Among lots of feasible approaches to avoid congestion efficiently, congestion-aware routing protocols tend to search for an uncongested path toward the destination through rule-based approaches in reactive/incident-driven and distributed methods. However, these previous approaches have a problem accommodating the changing network environments in autonomous and self-adaptive operations dynamically. To overcome this drawback, we present a new congestion-aware routing protocol based on a Q-learning algorithm in software-defined networks where logically centralized network operation enables intelligent control and management of network resources. In a proposed routing protocol,… More

  • Kernel Search-Framework for Dynamic Controller Placement in Software-Defined Network
  • Abstract In software-defined networking (SDN) networks, unlike traditional networks, the control plane is located separately in a device or program. One of the most critical problems in these networks is a controller placement problem, which has a significant impact on the network’s overall performance. This paper attempts to provide a solution to this problem aiming to reduce the operational cost of the network and improve their survivability and load balancing. The researchers have proposed a suitable framework called kernel search introducing integer programming formulations to address the controller placement problem. It demonstrates through careful computational studies that the formulations can design… More
