Mobile applications are evolving rapidly, requiring accurate and highly sophisticated computational methods such as machine learning (ML) techniques. Their processing power requirements cannot be supported in a mobile device with reasonable latency and energy consumption.
Currently these applications are designed based on hosting all computation in high-end remote cloud servers. Queries generated from users’ mobile devices are sent to the cloud for processing. In this approach, large amounts of data (e.g., images, video and audio) are uploaded to the server via multiple networks, resulting in high latency and energy costs.
To overcome these issues, emerging solutions are designed to host all the computation at the edge computing servers close to users. The drawbacks of this approach include limited computing capability at the edge, network delay and its variation (wireless network) and complexity to handle mobility of users from edge to edge.
Another recent technological solution is Split Computing. In this approach, computing tasks are split and executed between the mobile devices, the edge compute resource and the cloud.
Realizing split computing requires advanced techniques for breaking a computational task , e.g. Deep Neural Network (DNN ) into head and tails ends for execution in mobile, edge and cloud. It also requires close orchestration between application and a network in order to provide low latency connectivity between different parts of a computing tasks split across mobile, edge and cloud data center. This becomes even more challenging when users are mobile and in highly dense scenarios.
This workshop aims to discuss challenges and possible solutions as well as opportunities for optical technologies for realizing next generation edge computing based on split computing.
