On the quality and value of information in sensor networks

Abstract

The increasing use of sensor-derived information from planned, ad-hoc, and/or opportunistically deployed sensor networks provides enhanced visibility to everyday activities and processes, enabling fast-paced datato-decision in personal, social, civilian, military, and business contexts. The value that information brings to this visibility and ensuing decisions depends on the quality characteristics of the information gathered. In this article, we highlight, refine, and extend upon our past work in the areas of quality and value of information (QoI and VoI) for sensor networks. Specifically, we present and elaborate on our two-layer QoI/VoI definition, where the former relates to context-independent aspects and the latter to context-dependent aspects of an information product. Then, we refine our taxonomy of pertinent QoI and VoI attributes anchored around a simple ontological relationship between the two. Finally, we introduce a framework for scoring and ranking information products based on their VoI attributes using the analytic hierarchy multicriteria decision process, illustrated via a simple example.

Towards the internet of everything: Deployment scenarios for a QoO-aware integration platform

“…Among them, we can cite Quality of Service (QoS) [1], Quality of Information (QoI) [7] or even Context annotation [8]. Such quality dimensions generally define quality attributes that aim at characterizing how fit-for-use is an observation for a specific use by an application (specific context).…”

“…In particular, these works have focused on maximizing the network lifetime together with improving either the Quality-of-Service (QoS) or qualityof-information [3][4][5][6]. In recent past, however, the focus has been changing to more of a user-centric approach.…”

A two-queue model for optimising the value of information in energy-harvesting sensor networks

“…In the context of sensor networks, a refinement of the familiar concept of Quality of Service (QoS) has been proposed, referred to as "Quality of Information" (QoI), which takes into account on the quality but also on the timeliness of the information [3,4,5]. In this paper, we make use of this new concept and keep track of the value of information that is currently stored in the sensor node.…”
