Pervasive computing is, in its core, an application-driven discipline encompassing the pervasive acquisition, transportation, processing, and consumption of information from diverse sources, including widespread sensor deployments. Thus, the traditional study of Quality of Service (QoS) in transporting sensory data in pervasive systems must be balanced with the Quality of Information (QoI) in delivering sensor-originated information. QoI, also known as Information Quality (IQ), relates to the information's level of fitness for a purpose. Harnessing and optimizing the QoI derived from pervasive systems will be the key to effectively tying together information acquisition, transportation, processing, and consumption processes and facilitating the broad spectrum of smart, information-intensive, and sensor-enabled pervasive applications. The IEEE International Workshop on Information Quality and Quality of Service for Pervasive Computing (IQ2S) was created with this complementary view of QoI and QoS in mind. Now in its second year, the goal of the Workshop is to provide a forum to exchange ideas, present results, share experience, and enhance collaborations among researchers, professionals, and application developers for advancing the theory and practice of this new, important and challenging area in wireless sensor networks for pervasive computing.
