Abstract

In this paper, we propose a new operating system abstraction, called a common, for mobile appliances. We can use a common to prevent the excessive use of computational resources on appliances.Mobile appliances will have networked servers such as a http server. We need a new resource abstraction for mobile appliance OS to protect relatively precious and limited resources against service requests from the Internet.The common abstraction can restrict accesses of machine resources and maintain stability on appliances against unknown users on the Internet. We describe two applications of the common: resource allocation for a WWW server and restriction on a bad influence of DoS attacks.In the next section, we describe system requirements for mobile appliance OS and point out its needs. In Section 3, we describe the abstraction of a common. Section 4 describe the applications of commons. In Section 5 we describe current status of our project. Section 6 discusses related work and Section 7. concludes.
