As a new paradigm of sensing in the Internet of Things, the mobile crowdsensing network takes advantage of ubiquitous sensing device within a specific range to collect sensing data of individuals, situations and environments for a variety of applications. This paper introduces the current application development of the mobile crowdsensing network, analyzes the development trend of intelligent transportation services, infrastructure and municipal management, environmental monitoring, early warning, social relations and public safety, public health and medical services. Then it proposes a number of security challenges faced by the mobile crowdsensing network in the future, including user privacy protection, security of the sensing data and platform, the improvement of sensing quality and efficiency, and resources consumption optimization.
