**** Scope *****
Ubiquitous sensors, connected devices, smart objects, networking advances, and diverse data sets are the driving force towards a smart world within which computational intelligence is embedded in the physical environment to provide trustworthy, personalized, and adaptive services to people. This ubiquitous intelligence (UI) changes the computing landscape by enabling new breeds of applications and systems previously impossible. For example, by coupling everyday objects with intelligence (i.e., sensing, computing, and reasoning capabilities), many tasks can now be simplified and automated. As a result, our living and working environments become smarter, more comfortable, and more efficient.

Crowd sensing technology has become an important part of ubiquitous computing, and it has found pervasive use in a variety of applications ranging from environment/residential monitoring, intelligent transportation and traffic planning, urban dynamics sensing, public health and safety, to location based services. The need of understanding urban, society and environment dynamics to enable large-scale ubiquitous computing applications leads to a number of challenges on crowd sensing technology, such as 

(1)Task allocation. Considering the large population of mobile nodes, a sensing task must identify which node(s) may accept a task. Meanwhile, a set of criteria should be considered in filtering irrelevant nodes, such as the specification of a required region (e.g., a particular street) and time window, acceptance conditions, device capabilities, and termination conditions.

(2)Team formation. Interactions among volunteers are necessary during the sensing process, but absent in most existing crowd sensing systems. Therefore, grouping users and facilitating the interaction among them should be a challenge of CSUI.

(3)Incentive mechanisms. To sense and process the desired data, participating devices may incur energy and monetary costs, or even explicit efforts from their owners. Without strong incentives, individuals may not be willing to participate in the sensing task with cost of their own limited resources. Therefore, a successful crowd sensing system must have an appropriate incentive mechanism to recruit, engage, and retain its participants

(4)Data Redundancy, Quality, and Inconsistency. In crowd sensing, there can be multiple participants involved in the same sensing activity, providing data with various quality. Therefore, CSUI would raise data redundancy and inconsistency issues.	

(5)Ubiquitous intelligence extraction. With the increase in the large-scale, interlinked data collected from crowds, advanced techniques on mining, association, aggregation, and semantic fusion of the crowdsourced cross space and heterogeneous data will become more and more important.
	
(6)Trust, security and privacy issues. Malicious users may deliberately pollute crowdsourced data for their own benefits. Therefore, trust maintenance and abnormal detection methods should be developed to determine the trustworthiness and quality of collected data. Meanwhile, to motivate user participation, a crowd sensing system must be capable of effectively protecting the privacy of participants while allowing their devices to reliably contribute high-quality data to these large-scale applications.
