Architecture Strategies for Cyber-Foraging: Preliminary Results from a Systematic Literature Review

Abstract

Mobile devices have become for many the preferred way of interacting with the Internet, social media and the enterprise. However, mobile devices still do not have the computing power and battery life that will allow them to perform effectively over long periods of time or for executing applications that require extensive communication or computation, or low latency. Cyber-foraging is a technique to enable mobile devices to extend their computing power and storage by offloading computation or data to more powerful servers located in the cloud or in single-hop proximity. This paper presents the preliminary results of a systematic literature review (SLR) on architectures that support cyberforaging. The preliminary results show that this is an area with many opportunities for research that will enable cyber-foraging solutions to become widely adopted as a way to support the mobile applications of the present and the future.

A tale of three systems: Case studies on the application of architectural tactics for cyber-foraging

“…Cloudlet discovery is based on the Avahi daemon 1 that implements Zeroconf (Zero Configuration Networking). 2 Avahi uses DNS Service Discovery (DNS-SD) along with Multicast DNS to enable a client to request a service without knowing the IP address of the server that provide the service. Cloudlet discovery by cloudlet-ready apps takes place as follows: replies with a DNS-SD Response indicating the IP address and port of the cloudlet server.…”

“…In addition to successful test results, data collected included cloudlet provisioning time, energy consumption on the mobile device, payload size and response time. All implementation details and supporting data are available in several publications [2,6,10,11].…”

“…In previous work we conducted a systematic literature review (SLR) on architectures for cyber-foraging systems [2,3]. The common design decisions present in the cyber-foraging systems identified in the SLR were codified into functional and non-functional architectural tactics [3,4].…”

A Catalog of Architectural Tactics for Cyber-Foraging

“…One of these system-level concerns is security [19]. A scenario for Security is the following: A mobile app is enabled for cyber-foraging and is in the process of discovering a surrogate for computation offload.…”

“…A set of 57 primary studies was identified (their preliminary analysis is available in [19]). The studies were categorized based on decisions regarding the following concerns:…”
