Concurrent opportunistic sensor environments (COPSE) aim to create a decentralized peer-to-peer platform for harnessing the computational resources within a geographic area for mobile and pervasive services. The nodes within an area can be a mix of fixed elements like access points and highly mobile devices like mobile phones. Nodes contribute resources such as virtual machine hosting or Internet connectivity voluntarily and can revoke resources without notification. Services execute across a heterogeneous set of elements and are composed of individual virtual machine instantiations. Depending on the nodes running them, service instantiations may execute across different energy budgets, communication technologies, and storage quotas. For COPSE to succeed, it must marshal enough volunteered resources for services to run and expose information about the rapidly changing availability of resources so that services can adapt to churn. This requires meeting research challenges in two broad areas. The first area is virtual machine interfaces that expose changes in local resources and co-located nodes; these interfaces will allow services to reconfigure themselves in response to resource churn. The second area is minimizing the opportunity costs of participating in cooperative mobile systems like COPSE; pocket hypervisors must provide mechanisms and policies that protect device owners and concurrently running services from buggy or malicious instantiations.

并发机会传感器环境（COPSE）的目标是创建一个分散的对等平台，利用地理区域内的计算资源的移动的和普适服务。 区域内的节点可以是固定元素（如接入点）和高度移动的设备（如移动的电话）的混合。节点自愿贡献资源，如虚拟机托管或互联网连接，并可以在不通知的情况下撤销资源。服务跨一组异构元素执行，并由各个虚拟机实例化组成。根据运行它们的节点，服务实例化可以跨不同的能量预算、通信技术和存储配额执行。为了使COPSE取得成功，它必须为服务调度足够的自愿资源，以运行并公开有关快速变化的资源可用性的信息，以便服务能够适应客户流失。 这需要在两个广泛的领域迎接研究挑战。第一个领域是虚拟机接口，它暴露本地资源和协同定位节点中的更改;这些接口将允许服务重新配置自己以响应资源变动。第二个领域是最小化参与COPSE等协作移动的系统的机会成本;袖珍虚拟机管理程序必须提供保护设备所有者和并发运行的服务免受错误或恶意实例化的机制和策略。
