Energy-Aware Task Allocation for Multi-Cloud Networks
Smart algorithm to optimize performance of the heterogeneous multi-cloud network
Dr Sambit Kumar Mishra
As the world goes more digital in the future, the dependability on cloud computing is going to be more. The availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture and autonomic and utility computing has led to growth in cloud computing. But is it enough? How to improve its performance? How to make it more reliable with high-end technology and impeccable performance quality? Dr Sambit Kumar Mishra’s research has an answer to that.
System Model for Multi-cloud Networks Dr Sambit Kumar Mishra, Assistant Professor, Computer Science and Engineering has published a paper “Energy-Aware Task Allocation for Multi-Cloud Networks” in renowned journal IEEE ACCESS with an Impact Factor: 3.745. The research was done in collaboration with Dr Sonali Mishra, SOA (Deemed to be) University Bhubaneswar, India; Dr Ahmed Alsayat, College of Computer and Information Sciences Jouf University, Al-Jouf, Saudi Arabia; Dr N Z Jhanjhi and Dr Mamoona Humayun, School of Computer Science and Engineering (SCE), Taylor’s University, Malaysia; Dr Ashish Kr. Luhach, The PNG University of Technology, Papua New Guinea Lae, Morobe; Dr Kshira Sagar Sahoo, VNRVJIET, Hyderabad, India.
Example of Direct Acyclic Graph (DAG)with four TasksIn recent years, the growth rate of Cloud computing technology is exponentially, mainly for its extraordinary services with expanding computation power, the possibility of massive storage and all other services with the maintained quality of services (QoS). The task allocation is one of the best solutions to improve different performance parameters in the cloud, but when multiple heterogeneous clouds come into the picture, the allocation problem becomes more challenging. This research work proposed a resource-based task allocation algorithm. The same is implemented and analysed to understand the improved performance of the heterogeneous multi-cloud network. The proposed task allocation algorithm (Energy-aware Task Allocation in Multi-Cloud Networks (ETAMCN)) minimizes the overall energy consumption and also reduces the makespan. The results show that the makespan is approximately overlapped for different tasks and does not show a significant difference. However, the average energy consumption improved through ETAMCN is approximately 14%, 6.3%, and 2.8% in opposed to the random allocation algorithm, Cloud Z-Score Normalization (CZSN) algorithm, and multi-objective scheduling algorithm with Fuzzy resource utilization (FR-MOS), respectively. An observation of the average SLA-violation of ETAMCN for different scenarios is performed.
Energy Consumption Vs SLA Violation when
the number of VMs varies and the number of Task is 100.The multi-cloud strategy offers flexibility to service providers. It allows businesses to be productive while using the proper set of services to optimize their opportunities. Adopting a multi-cloud network enables an enterprise to implement a “best of breed” model for the services. Organizations’ ability to choose the vendor that offers the best price for their workload is added significant advantage of multi-cloud. Thus, the optimization of energy consumption in a multi-cloud environment is necessary for the current generation.
However, this proposed work has not considered any priority-oriented users, such as task execution through reserve resource in the network, which will be considered as his future work. The future work also aims to propose a task cum resource-aware scheduling approach that will exploit the nature of the presented workload and efficiently map on the available Cloud resources so that energy consumption will optimize.

DST, Government of India sanctions an outlay of Rs.14.63 lakhs to Dr Tapan Kumar Hota
Connecting the dots between Mathematics and Physics of the hydrodynamic instability known as Viscous Fingering (VF)
DST, Government of India, sanctioned a total outlay of Rs.14.63 lakhs to Dr Tapan Kumar Hota, Assistant Professor, Department of Mathematics, SRM University-AP, Andhra Pradesh, for pursuing research on “Mathematical analysis and Adjoint Based Stability for a Coupled Convection-Diffusion equation in Miscible Displacement”. Hydrodynamic Stability (Instability) is a study of an equilibrium point subject to small and/or medium disturbances. This assists in understanding several complicated natural phenomena such as fluid transition from laminar to turbulent, chemical mixing, formation of cloud, and others. The available stability analysis is unable to address the early-time evolution of the VF process. The early-time behaviour of the system helps us to choose the parameters that are responsible for the long-time behaviour of the coupled PDEs. To achieve the target, we need to address the linear stability of the system from the study of the singular-value-decomposition instead of traditional eigenvalue analysis. As the system is non-autonomous, the eigenvectors/eigenvalues may not be physically relevant. Further, it is required to confirm our linear stability analysis by mathematical analysis of the coupled non-linear PDEs.
‘The nonmonotonic viscosity profile when a high mobile fluid is displacing a less mobile fluid. There is a potentially unstable region, where the viscosity increases in the flow direction, followed in the downstream direction by a potentially stable region, where the viscosity decreases in the flow direction. The disturbance structure is computed using the singular-value decomposition of the propagator matrix. Reference: Hota & Mishra, Journal of Fluid Mech, Vol. 856, pp:552-579, 2018.’
Dr Tapan is keen on studying other branches of science to provide the correct mathematical approach to address the issues. His project will address one of the hydrodynamic instabilities known as viscous fingering (VF). It forms when a high mobile fluid displaces a low mobile fluid. It has enormous implications in the field of Chemical Engineering Science, Petroleum Engineering, Chromatography, and Oil Extraction process. He explains, “I will study this instability from a mathematician’s point of view, more precisely, to address the mathematical analysis of coupled partial differential equations (PDEs). The system that governs the VF is non-autonomous and there is no readily available stability analysis that can represent Physics, based on robust mathematical analysis. My aim is to connect the dots between mathematics and physics of the VF.”
Infrastructure and laboratory facilities are crucial to conduct research. Upon receiving approval from a prestigious organization like SERB (Science and Engineering Research Board), Govt. of India, Dr. Tapan is entitled to this unique opportunity to serve the scientific community. He divulges, “The award is not only a recognition to me but also to the SRM University, AP. The University will be more visible in the world of research and can attract more eminent scientists and researchers to make the University their second home.” Quoting Master Oogway, ‘Yesterday is history, Tomorrow is a mystery… Today is a gift, that’s why it is called present.’, Dr Tapan is eager to commence working on his project at the earliest, and looks forward to enjoying the process of accomplishing the task.

ECE Undergrads developed AI-based communication app for deaf and blind
Won prestigious i-Hack Alpha with a cash prize of $2300
Department of Electronics and Communication Engineering rejoices in the exhilarating success of Harsha and Mahesh, the winners at iHack Alpha Hackathon. iHack Alpha was an AI-Hackathon, where developers from all backgrounds were invited to solve real-world problems with innovative AI solutions powered by sentient.io AI and Data platform. Unlike the usual hackathons, it was conducted over three weeks, starting from December 2, 2020, and finished on December 27, 2020, and participants were supposed to present a full-fledged application. Four themes were given to participants to work on in the hackathon- 1) Use of AI in retail 2) Use of AI in Customer service 3) Use of AI in media 4) Use of AI in Accessibility.
Harsha and Mahesh chose to work on the use of AI in the Accessibility theme, where they were asked to build an AI – solution using the sentient.io services. The whole hackathon was divided into three phases 1.) Ideation Phase 2) Build Phase 3) Finals.
Around 1083 teams participated across countries such as India, Malaysia, the Philippines, Indonesia, and Singapore.
Harsha and Mahesh found their inspiration in the story of Helen Keller and decided to build an app with ease of accessibility for the blind and deaf persons. As Annie Sullivan used to help Helen in her communication, Harsha and Mahesh thought, why can’t they create an app which can be installed on the mobile phone and will do the same! The duo turned this crazy idea into reality by developing Artificial Voice- a communication app for the blind and deaf. Artificial Voice is a bidirectional communication app for the deaf and blind to send and receive messages with the help of AI-based technology such as Automatic Speech recognition, Text to speech converter, Audio format converter.
The whole Hackathon was broadcasted online. Harsha and Mahesh’s presentation on Artificial Voice received high praise and acclaims from the judges, and the Team SRMAP(aka Team Square) secured first place in the prestigious i-Hack Alpha hackathon with a grand cash prize of $2300. Harsha is currently pursuing his 3rd year B. Tech Studies whereas Mahesh is in the 2nd year of his undergraduate studies at the Department of Electronics and Communications Engineering. “This success at i-Hack Alpha hackathon has boosted our confidence. We are working on better versions of the app and some other projects that can contribute to society,” said Harsha.
