“…System-level virtualization of mobile devices has been proposed and implemented by both researchers [5,8,3] and commercial entities [6,12]. We agree with their conclusions that virtualization improves the security and manageability of mobile computing, and add our insight that virtualization would also enable seamless switching between devices.…”

“…This paper proposes VMsync, a system for synchronizing the state of live virtual machines (VMs) among mobile devices. System-level VMs have been widely proposed to improve the security, manageability, and other aspects of mobile computing [3,5,6,8,12]. In the context of device switching, VMs encapsulate both data and computation state for a complete operating system and all its applications.…”

The mobile computing experience would improve if users could switch seamlessly from one device to another, with both data and computation state preserved across the switch without apparent delay. This paper proposes VMsync, a system for synchronizing the state of live virtual machines (VMs) among mobile devices. VMsync seeks to incrementally transfer changes in an active VM on one device to standby VMs in other devices, so as to maintain a consistent VM image and minimize switching latency. However, constraints of the mobile environment make these goals difficult to achieve and raise many research questions. We present our preliminary design for VMsync and a feasibility study aimed at determining how much data would need to be transferred under different mobile workloads and synchronization policies. For example, through experiments with a Xen VM running Android and playing a YouTube video, we show that sending dirty memory pages transfers 3 times more data than sending only the bytes that actually changed in those pages. Overall, we conclude that VMsync is a feasible approach deserving of further research.

“…Researchers have also explored the use of on-device virtualization for mobile security applications [2]. In our prior work, we demonstrate that while the effectiveness of desktop antivirus is inadequate against modern threats [12], a virtualized in-cloud network service [13] fares much better.…”

Modern mobile devices continue to approach the capabilities and extensibility of standard desktop PCs. Unfortunately, these devices are also beginning to face many of the same security threats as desktops. Currently, mobile security solutions mirror the traditional desktop model in which they run detection services on the device. This approach is complex and resource intensive in both computation and power. This paper proposes a new model whereby mobile antivirus functionality is moved to an off-device network service employing multiple virtualized malware detection engines. Our argument is that it is possible to spend bandwidth resources to significantly reduce on-device CPU, memory, and power resources. We demonstrate how our in-cloud model enhances mobile security and reduces on-device software complexity, while allowing for new services such as platformspecific behavioral analysis engines. Our benchmarks on Nokia's N800 and N95 mobile devices show that our mobile agent consumes an order of magnitude less CPU and memory while also consuming less power in common scenarios compared to existing on-device antivirus software.

“…To this end, JellyNets rely on autonomous pocket hypervisors [10] to export a virtualized hardware interface to developers and manage devices' physical resources. Pocket hypervisors are identical to desktop hypervisors like Xen and VMware in most ways, but they provide an extended interface to support virtualized wireless communication (e.g., WiFi and Bluetooth), and they contain additional mechanisms and policies to ensure power isolation.…”

Programmable consumer devices have placed computation within arm's reach at all times and in all places. Unfortunately, researchers interested in investigating this phenomenon often struggle with the expense, inconvenience, and limited scale of existing experimental platforms. In this paper, we introduce a new experimental platform for mobile and pervasive computing based on JellyNets, an abstraction for exposing experiments to arbitrary mobile social contexts.
