1、填空题：
Mobile phone sensing is a relatively new topic that requires further academic research. Below are extracts from several academic articles discussing mobile phone sensing. Read the extracts and write down the number of the sentence or sentences that indicate the literature gaps identified by the authors that require further research. (答案写句子编号，若有多个选择，编号间空格)TEXT 11.Most examples of community sensing only become useful once they have a large number of people participating; for example, tracking the spread of disease across a city, the migration patterns of birds, congestion patterns across city roads[5], or a noise map of a city[24]. 2.These applications represent large-scale data collection, analysis, and sharing for the good of the community. 3.To achieve scale implicitly requires the cooperation of strangers who will not trust each other. 4.This increases the need for community sensing systems with strong privacy protection and low commitment levels from users.

2、填空题：
TEXT 21.Even though they possess much more computing, bandwidth, and energy resources than mote-class sensors, mobile devices nevertheless face resource limitations. 2.Resource constraints in traditional sensor networks have been well studied. 3.However, MCS applications introduce new aspects in this regard. 4.First, the set of devices that are collecting sensor data are highly dynamic in availability and capabilities. 5.Due to this highly dynamic nature, modeling and predicting the energy, bandwidth requirements to accomplish a particular task is harder than traditional sensor networks. 6.Second, when there are a large number of available devices with diverse sensing capabilities, identifying and scheduling sensing and communication tasks among them under resource constraints is more complex.

3、填空题：
TEXT 31.An important aspect of MCS [mobile crowdsensing] applications is that they potentially collect sensitive sensor data pertaining to individuals. 2.For example, GPS sensor readings can be utilized to infer private information about the individual, such as the routes they take during their daily commutes, home, and work locations[9]. 3.On the other hand, these GPS sensor measurements (from daily commutes) shared within a larger community can be used to obtain traffic congestion levels in a given city[4]. 4.Thus, it is important to preserve the security and privacy of an individual, but at the same time enable MCS applications. 5.It is also necessary to ensure that an individual’s sensor data is not revealed to untrustworthy third parties. 6.A problem that arises from the opt-in nature of crowdsensing applications is when malicious individuals contribute erroneous sensor data (e.g. falsified GPS readings), maintaining the integrity of sensor data collected is an important problem.Source: Ganti, R. K., Ye, F. & Lei, H. (2011). Mobile crowdsensing: Current state and future challenges. IEEE Communications Magazine, 49 (11): 32-39.
