Crowd-Based Mobile Sensor Cloud Services — Issues, Challenges and Needs

As an important part of IoT infrastructures, sensors have become essential elements of today and future connected smart world. The fast advance of sensor and mobile sensor technologies and the increasing deployments of connected sensor networks bring a strong demand and many business opportunities in develop new mobile sensor cloud infrastructures and related services applications. Mobile sensor clouds based on crowd sensors from users is one of them. This paper focuses on this topic by discussing the trend and opportunities first. Then it presents an overview of crowd-based mobile sensors in terms of its concepts, features, process and applications. Moreover, it discusses a reference infrastructure on a crowd-based mobile sensor cloud. Finally, it discussed its issues, challenges and needs.
