Research Interest

Research Projects

LTE-WiFi Spectrum Aggregation (LWA)

WiFi offloading is the best option to reduce the burden of cellular networks. So, aggregating indoor WiFi technology to the cellular network increases the network capacity and provides better QoS to customers. In this project, we have implemented the LTE-WiFi aggregation (LWA) system, where eNodeB aggregates the WiFi access point without modifying the core network. Furthermore, the LWA system is integrated with the mobile-CORD (M-CORD) platform, which leverages software-defined networking (SDN), network function virtualization (NFV), and cloud technologies for providing a 5G environment.

Network Slice LCM through Intent-based Networking

This project proposes an efficient solution that automates the configuration process and performs the management and orchestration of network slices. This solution contains a one-touch Intent-based Networking (IBN) platform that effectively orchestrates and manages the lifecycle of multi-domain slice resources. IBN automates the process of slice configuration generation, service provisioning, service update, and service assurance by eliminating experts and manual effort. Furthermore, it has an intelligent Deep Learning (DL) based resource update and assurance mechanism, which handles the run-time resource scalability and assurance.

Network Data Analytics for 5G Slicing

The third generation partnership project (3GPP) introduced artificial intelligence (AI) based network data analytics function (NWDAF) in 5G architecture for proactive management and control of network resources. NWDAF allows NOs to develop machine learning (ML) algorithms to manage networks intelligently. Therefore, we have proposed an Intent-based Networking (IBN) mechanism for automating and managing e2e network slicing and an AI-driven network data analytics mechanism for proactive and intelligent resource update and assurance. The network data analytics mechanism uses a hybrid stacking ensemble learning (STEL) algorithm to predict short-time network resource utilization and a novel Automated Machine Learning (autoML) and voting ensemble learning-based mechanism to detect and mitigate network anomalies.

Autonomous VM Consolidation in Cloud Data Centers

This work proposes an energy-efficient autonomous VM consolidation mechanism that has Deep Reinforcement Learning (DRL) based agent for performing VM consolidation decisions. The DRL agent learns the optimal distribution of VMs in the data center, considering energy efficiency and QoS assurance.

AI-based VNF resource Forecasting 

This work introduces an efficient mechanism that uses Adaptive Ensemble Learning to predict resource usage of virtual network functions. This mechanism has three modules: Machine-Learning Predictors (MLPs), Predictor Selectors (PS), and Predictor Combiner (PC). The MLPs module contains several ML models for performing prediction. The PS module has a trained Random Forest model that chooses the best predictors from the MLPs. The PC module combines the selected predictors using an ensemble learning mechanism to generate the final prediction.
