ΨPervasive Services Infrastructure

Future systems have been characterized as ubiquitous, pervasive, and invisible. They will consist of devices that are diverse in size, performance, and power consumption. Some of these devices will be mobile, posing additional requirements to system software and applications. The focus will move from technology to deployment and ease of use of services. Consequently, traditional paradigms for reasoning about, designing, and implementing software systems and services will no longer be sufficient. We believe that this future vision will rely on a three-tier infrastructure consisting of back-end servers, infrastructure servers, and front-end clients (mobile or static, handheld or embedded). The critical question for future systems will be how to deliver services on demand from back-end servers to resource-constrained clients. If we can handle the new requirements of these systems, we can enable this computing infrastructure to offer significantly more services to users in a more pervasive way.
