Survey on IoT-based Big Data Analytics

Nowadays, the fast development of the internet and 5G technology encouraged the emergence of many technologies that enhanced the human lifestyle. Moreover, the wide spread of Internet of Things (IoT) gadgets contributed significantly to this technological transformation and provided individuals with pleasure and simplified their lives. Many systems have been developed using sensor-based devices, i.e., IoT devices, e.g., smart healthcare, smart transportation, smart agriculture…etc. Consequently, it became the main source of huge amount of data that are collected frequently, named Big Data. However, such collected data is useless without applying analytics that discover new insights. This data is massive, collected at a rapid speed, and in different formats, constituted the big data main characteristics; volume, velocity, and variety (3Vs). Performing analytics on big data, i.e., Big Data Analytics (BDA) has many challenges that are most probably related to its characteristics. This paper will undertake a survey on Big Data technologies covering various IoT domains. This survey discusses overview of IoT as the main source of big data, big data analytics mechanisms, methodologies, architecture, use cases, challenges and finally the existing frameworks and tools for analytics.
