How close is close enough? Understanding the role of cloudlets in supporting display appropriation by mobile users

Abstract

Abstract-Transient use of displays by mobile users was prophesied two decades ago. Today, convergence of a range of technologies enable the realization of this vision. For researchers in this space, one key question is where to physically locate the application for which the display has been appropriated. The emergence of cloud and cloudlet computing has increased the range of possible locations. In this paper we focus on understanding the extent to which application location impacts user experience when appropriating displays. We describe a usage model in which public displays can be appropriated to support spontaneous use of interactive applications, present an example architecture based on cloudlets, and explore how application location impacts user experience.

Upgrading Wireless Home Routers for Enabling Large-Scale Deployment of Cloudlets

“…We tested 15 different scenarios consisting of local and offloading processing: (1) locally on the device, (2) cloudlet over wireless LAN, (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) three different located clouds (US West, EU, Asia Pacific) over four different wireless networks (2G, 3G, 4G, wireless LAN/DSL), and (15) our router-based cloudlet concept over wireless LAN. The theoretical and measured network configuration used in our benchmark tests can be found in Table 5.…”

“…Thus, we test three different located clouds (US West, central Europe, Asia Pacific) with same computational power to get the impact of network latency [8]. In Table 2, linear distances between our measurement conducting location (Darmstadt, Germany) and the cloud data centers are listed.…”

“…In Ref. [13] demonstrated that deploying cloudlets in close proximity with the end user improves the execution of latency-critical applications.…”

User Experience of Mobile Cloud Applications - Current State and Future Directions

“…The overhead of this approach may be too demanding for simple tasks. A study by Clinch et al [3] showed that latency for less demanding applications did not adversely affect performance to a large degree. We believe that bandwidth will in fact be a concern as the number of users of the Cloudlet grows.…”
