Pervasive computing enables devices to interact with the real world in a ubiquitous and natural manner. Quality of service (QoS) related to transmission delay, bandwidth, and packet loss has been studied for various building blocks in pervasive computing (e.g., different QoS mechanisms were introduced for wireless and wired networks and the notion of computational QoS has been used in parallel processing). The emerging pervasive computing, however, is application-driven and mission-critical, and the above QoS notion does not easily apply anymore. Quality of Information (QoI) or Information Quality (IQ) of sensor-originated as well as human-originated information relates to the fitness of the information for a data-consuming application. Harnessing and optimizing QoI of information derived from networked data sources, such as sensors and people, will be the key to bringing together information acquisition systems and data processing algorithms that support the on-demand information needs of a broad spectrum of smart data-driven applications, such as remote real-time habitat monitoring, utility grid monitoring, environmental control, supply-chain management, health care, machinery control, intelligent highways, military intelligence, reconnaissance and surveillance (ISR), border control, and hazardous material monitoring, just to mention a few.

QoI relates to every part of the end-to-end flow of information, starting from sensors (broadly defined), together with the observation data they produce, and ending up in the various data fusion processes that handle these data and eventually deliver the processed data to the applications (and their users). For example, sensor-generated information is used as the basis for determining context at varying levels of accuracy and fidelity, in a hierarchical fashion, with lower-layer context effectively serving as a virtual sensor stream for higher-layer context determination. The effectiveness of actions taken by the applications using this information serves as the ultimate assessor of the quality and value-added that is provided by the entire sensor-enabled application. For example, an action can be highly effective and achieving all its anticipated goals, only partially effective, or entirely ineffective. Complementing “traditional” provisioning of QoS with QoI for pervasive computing is a challenging and difficult task due to the resource-constrained, dynamic and distributed nature of the system, the weakness presented by security attacks, and the complexity and lack of a design approach that takes into account the different types of resources and their inter-dependencies. Novel mechanisms are needed in pervasive computing which should integrate QoI, network QoS, computational QoS, security, and a user’s Quality of Experience (QoE), which will be influenced by the applications’ requirements and by the characteristics of the pervasive environment in which the applications are to be utilized.

The objective of this workshop is to provide a forum to exchange ideas, present results, share experience, stimulate new research, and foster collaborations among researchers, professionals, and application developers on the various aspects of QoI and QoS for pervasive computing.
