Challenges in collecting and transmitting data from resource-constrained IoT devices

The Internet of Things (IoT) is the new hot trend in computer science and information technology. IoT devices collect different types of data through a diversity of sensors. Today IoT data is very much valuable. There are two types of data transmission requirements - real-time or batch. Usually, the IoT data is unstructured and the IoT devices from different manufacturers format the data in different ways. This should be considered when the data is received in the cloud to transform it into a unified format to facilitate its further storage, processing, and analysis. A very important concern is to maintain data integrity and ensure security while transmitting the IoT data. The main challenge is how to store and transmit the collected information to achieve data aggregation. The current paper summarizes the challenges involved in the process of collection and transmission of IoT data. Specific approaches are proposed to address some of the communications challenges involved in the process of transmitting the collected information.
