Rapid advancements in smartphones, wireless sensors and mobile communications have led to the development of cyber-physical systems, smart environments, and pervasive computing with important applications in environmental, civilian, military, industry, and government sectors. Sensor networks and smartphones play significant roles in this context as they not only act as effective interface between physical and cyber worlds, but also bring in human social aspects. However, increasing scale and heterogeneity at all levels - users, devices, networking and computing technologies, information and services - implies a high degree of uncertainty in distributed control and operations of pervasive and cyber-physical systems, thereby posing significant challenges in providing desired information quality, assurance, and reliability for intelligent decision making. This is particularly important for applications like smart health care, smart energy management, and pervasive security.
