“…While certain industry efforts are aimed at better aligning the software stacks and components used for the development of such services [10], it remains clear that, given the multitude of industry partners, OEMs and software developers, different application will have different OS and runtime support requirements. Virtualization technology provides solutions for encapsulating different OS/runtime components with the corresponding application services in VMs, and for managing the physical hardware resources across different VMs according to the VM's QoS requirements [22,1,5].…”

“…Several industry and academic research projects are beginning to offer solutions or explore challenges related to virtualization of embedded platforms [22,1,12,6,9]. These efforts are primarily concerned with the performance isolation among the core device service, i.e., phone, and other device-resident applications [5,1], or with the security and trust management implications of running these additional applications [13]. Our work is focused on exploring the possibilities of virtualized embedded SoC platforms, including for the shared use of their tightly coupled accelerators.…”

Embedded platforms are becoming increasingly more resource-rich (e.g. processing speeds, number of cores, memory, and communication rates). As a result, they are being transformed from 'closed', fixed-function devices to programmable and flexible platforms capable of supporting diverse types of services. One approach to enabling service diversity jointly with proper isolation of key critical functionality is to leverage platform virtualization technology. Toward this end, this paper first describes an approach to virtualizing System-on-a-Chip (SoC) platforms, and next explores the opportunities for shared use of such virtualized SoC devices by multiple concurrently executing services. The research is conducted on the Intel Tolapai SoC which integrates an x86 core with a crypto accelerator, and using the Xen hypervisor.

Although Xen's isolated driver domain (IDD) model enables strong system isolation by limiting the impact of driver faults to the driver domain itself, it results in severe security problems when malware in a guest domain tries to abuse mobile device's limited system resources by sending an extreme number of I/O requests to the IDD. In order to solve this problem, this paper presents a fine-grained I/O access control mechanism in an IDD. Requests from guest domains are managed by an accounting module in terms of CPU usage, with the calculation of estimated CPU consumption using regression equations. The requests are scheduled by an I/O access control enforcer according to security policies. As a result, our mechanism provides precise control on the CPU usage of a guest domain due to I/O device access, and prevents compromised guest domains from CPU overuse, performance degradation, and battery drain. We have implemented a prototype of our approach considering both network and storage devices with a real smart phone (SGH-i780) that runs two paravirtualized Linux kernels on top of Secure Xen on ARM. The evaluation shows our approach effectively protects a smart phone against excessive I/O attacks and guarantees availability.

“…To this end, the JellyNet relies on the 802.11 timer synchronization function (TSF) of the site network to synchronize all stations. 802.11 TSF is accurate to within µs and timer interrupts in Xen can be delivered at the granularity of a single ms 1 . This is more than sufficient for synchronizing Virtual WiFi schedulers managing epochs of hundreds of ms.…”

“…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. Past work on performance isolation has shown that encapsulating application state within the virtual-machine abstraction can reduce Both commercial [1,30] and research [4,16,19] hypervisors for mobile devices exist, though for various non-technical reasons they are not suitable for our current prototype implementation. Trango and VirtualLogix are proprietary and closed-source, MobiVMM and L4 are incomplete research projects, and Samsung's robust port of Xen for ARM-based mobile phones is only partially public.…”

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.
