School of Computer Science Carnegie Mellon University Abstract 2 Design Rationale Odyssey is a set of extensions to the NetBSD operating system to In this paper we show that application-aware adaptation, a support adaptation for a broad range of mobile informnationaccess collaborative partnership between the operating system and applications. These applications execute on mobile clients but read applications, offers the most general and effective approach or update remote data on servers. Our goal in building Odyssey is to mobile information access. We describe the design of to enable mobile scenarios such as the following one. Odyssey, a prototype implementing this approach, and show how it supports concurrent execution of diverse mobile ap- 2.1 Motivation plications. We identify agility as a key attribute of adap- tive systems, and describe how to quantify and measure it. Consider a hypothetical scenario in which a tourist with a weamblc W
