Cloudlet-based cyber-foraging for mobile systems in resource-constrained edge environments

Abstract

First responders and others operating in crisis environments increasingly make use of handheld devices to help with tasks such as face recognition, language translation, decision-making and mission planning. These resource-constrained edge environments are characterized by dynamic context, limited computing resources, high levels of stress, and intermittent network connectivity. Cyber-foraging is the leverage of external resourcerich surrogates to augment the capabilities of resource-limited devices. In cloudlet-based cyber-foraging, resource-intensive computation is offloaded to cloudlets -discoverable, generic servers located in single-hop proximity of mobile devices. This paper presents several strategies for cloudlet-based cyber-foraging and encourages research in this area to consider a tradeoff space beyond energy, performance and fidelity of results.

A Comprehensive Survey on Fog Computing: State-of-the-Art and Research Challenges

“…The concept of cloudlet was proposed next by Satyanarayanan [38] in 2009. It is referred to as cloudlet-based cyber foraging in [39] and [40]. Cloudlets reuse modern cloud computing techniques such as virtual machine (VM) basedvirtualization.…”

MEC-ConPaaS: An Experimental Single-Board Based Mobile Edge Cloud

“…Edge computing originated from research efforts on Cloudlets, which propose to deploy a specific infrastructure at the edge of mobile networks to support dynamic application deployment in the immediate proximity of the end users [15], [16]. The outcome of this work is OpenStack++, an extension of the popular OpenStack cloud computing platform which includes mechanisms for application deployment in a fog computing context [13].…”

The Case for Robotic Wireless Networks

“…(2) Various corridors opening into the atrium of the engineering building, called Lab. (3) Single bedroom graduate student apartment, called Apartment. (4) Large single family home with APs placed in different rooms, called Home.…”

“…are reaching saturation. Many are beginning to believe that the next "jump" in network performance will emerge from new ways of organizing networks [1][2][3][4][5]. In considering new network organizations, we explore the possibility of merging wireless networking with robotics.…”

“…Small scale mobility can be used to compensate for small changes in network conditions, while full scale mobility can be triggered occasionally when the system moves to a skewed state, or a strict QoS requirement is ordered. In cellular networks, for instance, quad-copters could occasionally fly out from cell towers and position themselves strategically to meet users' demands -like a network cloudlet [2,3]. Infrastructure mobility could evolve as an on-demand service, a cost-effective and scalable alternative to over-provisioning.…”
