Obtaining resource controllability in service cooperation environments

In a ubiquitous computing environment, devices host services that are accessed by anonymous users. This causes threats of resource abuse through malicious attacks or resource scarcity through unintentional excessive service invocations. In this paper, the secure resource control for service sharing is presented which depends on two basic functionalities: access control and soft-state management. Services are grouped into virtual communities for secure access. Service cooperation through external orchestration can only be done within a virtual community. Services can be activated/deactivated by a device management service running on their host devices. Real-time resource utilization of services for virtual community applications is monitored. Therefore, resources on a shared device can be protected from malicious use and become controllable for special quality of service provisioning
