In recent years, new mobile devices and applications with different functionalities and uses, such as drones, Autonomous Vehicles (AV) and highly advanced smartphones have emerged. Such devices are now able to launch applications such as augmented and virtual reality, intensive contextual data processing, intelligent vehicle control, traffic management, data mining and interactive applications. Although these mobile nodes have the computing and communication capabilities to run such applications, they remain unable to efficiently handle them mainly due to the significant processing required over relatively short timescales. Additionally, they consume a considerable amount of battery power. Such limitations have motivated the idea of computation offloading where computing tasks are sent to the Cloud instead of executing it locally at the mobile node. The technical concept of this idea is referred to as Mobile Cloud Computing (MCC). However, using the Cloud for computational task offloading of mobile applications introduces a significant latency and adds additional load to the radio and backhaul of the mobile networks. To cope with these challenges, the Cloud’s resources are being deployed near to the users at the Edge of the network in places such as mobile networks at the Base Station (BS), or indoor locations such as Wi-Fi and 3G/4G access points. This architecture is referred to as Mobile Edge Computing or Multi-access Edge Computing (MEC). Computation offloading in such a setting faces the challenge of deciding which time and server to offload computational tasks to.
This dissertation aims at designing time-optimised task offloading decision-making algorithms in MEC environments. This will be done to find the optimal time for task offloading. The random variables that can influence the expected processing time at the MEC server are investigated using various probability distributions and representations. In the context being assessed, while the mobile node is sequentially roaming (connecting) through a set of MEC servers, it has to locally and autonomously decide which server should be used for offloading in order to perform the computing task. To deal with this sequential problem, the considered offloading decision-making is modelled as an optimal stopping time problem adopting the principles of Optimal Stopping Theory (OST).
Three assessment approaches including simulation approach, real data sets and an actual implementation in real devices, are used to evaluate the performance of the models. The results indicate that OST-based offloading strategies can play an important role in optimising the task offloading decision. In particular, in the simulation approach, the average processing time achieved by the proposed models are higher than the Optimal by only 10%. In the real data set, the models are still near optimal with only 25% difference compared to the Optimal while in the real implementation, the models, most of the time, select the Optimal node for processing the task. Furthermore, the presented algorithms are lightweight, local and can hence be implemented on mobile nodes (for instance, vehicles or smart phones).

Efficient data access in mobile cloud computing.
Siva Naga Venkata Chaitanya Vemulapalli
"This thesis focuses on the development of efficient data transfer mechanism among mobile devices using Mobile cloud computing paradigm. Mobile cloud computing is coupling of mobile computing and cloud computing. In the Mobile cloud computing paradigm, users connect to cloud service providers over the Internet and leverage the cloud resources to perform their processing, storage and communication tasks. In this thesis, the focus is on communication tasks among mobile devices performed using Mobile cloud computing paradigm.
Communication or data sharing among mobile devices is often limited by proximity of the devices. This limitation can be removed by employing Mobile cloud computing paradigm wherein each physical mobile device has a corresponding virtual machine in the cloud servers. All the computation and communication tasks can be offloaded to the virtual machines in the cloud retaining only a thin client in the physical device to display results. The exchange of data or communication between mobile devices is done through the corresponding virtual machines in the cloud.
In this work, we designed a layered architecture involving mobile devices, access points and cloud server together for efficiency. We also proposed pre-distribution scheme based on this architecture for efficient data sharing among potential users with supporting data access mechanism, update propagation mechanism and cache replacement mechanisms. We also performed complexity analysis for data access using the proposed architecture and scheme. Finally, simulated the proposed architecture and scheme with actual devices and verified the efficiency of the scheme."--Abstract, page iv.

So that identifying the order of execution of tiny task newlineover available resources has become a challenging issue. On the other side, newlinenot all organizations have the capability to afford the cost which required newlinepurchasing costlier resources. The growth of information technology has newlineopened the gate for such organizations to execute the jobs by inventing newlinedistributed, grid, parallel computing strategies. On the way with a growth of newlinegrid computing the modern cloud environment has been developed. The cloud newlineenvironment has the beauty of maintaining various organizations data in newlinedifferent data centers which are located in global locations. Also, the service newlineprovider enables the access of data through number of services which are newlineprovided by Cloud Service Provider (CSP). However, the growing size of newlineorganization and data increases the challenge of scheduling the resources and newlineexecuting the task given in form of request from the clients. Whatever the newlinestrategy being used for workflow management, the quality of service of the newlinecloud is depending on various constrains like the time complexity, power newlineconsumption, resource utilization. Towards the development of workflow management, different algorithms have been discussed earlier. Some of the algorithms consider the newlineexecution time or makes span time, but does not consider the other factors newlinelike throughput, energy utilization and so on. newline newline |

Nj r&d council honors pioneering contributions by princeton researchers.
By Office of Engineering Communications
August 15, 2024
Naveen Verma, Hossein Valavi, Hongyang Jia, and Brian Kernighan have been recognized by the Research & Development Council of New Jersey.
The Research & Development Council of New Jersey has recognized four Princeton Engineering researchers for their pioneering contributions to innovation.
Brian Kernighan won the Science & Technology Medal, the R&D Council’s highest honor, for his work on computer programming languages. Naveen Verma, Hongyang Jia and Hossein Valavi won an Edison Patent Award for their work on advanced computer hardware.
“From the inventions of the lightbulb to transistors to antibiotics, New Jersey has been — and continues to be — in the forefront of life-altering innovations,” said Colleen Ruegger, chair of the R&D Council Board of Directors and an executive at Novartis.
Kernighan, the William O. Baker *39 Professor in Computer Science, was recognized for his groundbreaking work on computer programming languages, particularly his role in developing C, one of the most widely used and influential programming languages in the computing industry. The medal is given annually to a New Jersey leader for extraordinary performance in bringing an impactful innovation to the marketplace.
Broadly, Kernighan’s work focuses on programming, software tools, application-oriented languages and technology education. He is the author of a series of books that have become known for their clarity and precision. Among them is “The C Programming Language” (Prentice Hall, 1978), co-written with Dennis Ritchie. The book, which is still in print, is known among programmers as “K&R” and is the fundamental text on the language. Kernighan has also written books on the Go and AWK programming languages.
After completing a Ph.D. in electrical engineering at Princeton and working for 30 years at AT&T Bell Laboratories, Kernighan joined the Princeton faculty in 2000. He has served as a director of undergraduate studies in the department since 2001. He is a member of the American Academy of Arts and Sciences and the National Academy of Engineering, as well as a recipient of the USENIX Association Lifetime Achievement Award.
Led by Verma , a professor of electrical and computer engineering and director of the Keller Center for Innovation in Engineering Education, the team reimagined computer chips to run powerful AI systems using much less energy than today’s most advanced semiconductors. This allows systems made with the Princeton technology to run AI programs directly on mobile hardware, rather than communicating over the cloud, enabling applications such as piloting software for drones or AI assistants that keep information securely on local devices.
Jia and Valavi were graduate students studying with Verma when they began working on the chip designs, which enable memory cells to perform complex computations without shuttling data back and forth to a central processor. Jia is now an assistant professor of electronic engineering at Tsinghua University in Beijing. Valavi is a lecturer in electrical and computer engineering at Princeton, with a continued research focus on the intersection of machine learning and efficient hardware design.
Earlier this year, Verma and his team partnered with the U.S. Defense Department’s largest research organization to investigate how the new hardware could be used in a range of mobile and space-based applications. EnCharge AI, a company co-founded by Verma in 2022, plans to release its first commercial chips, manufactured by TSMC, next year.
This year, 14 patents created by 66 inventors and five individual award winners will be honored during the 45th annual Edison Patent Award Ceremony and Reception on November 21 at Bell Works in Holmdel, NJ.
