“…LoRaWAN is becoming more popular in Smart cities and industrial applications because it is a low-cost long-range bi-directional communication protocol with very low power consumption. Using the LoRaWAN protocol to connect street lights to a LoRa gateway is an example of smart street lighting [6] [9] [37] [56] [57].…”

“…In order to get specific messages to specific Subscribers, MQTT introduced the Topic concept, as well as the MQTT Broker, which is a central point to which all subscribers will be connected. A Subscriber will subscribe to a specific topic then, and the MQTT broker will filter the messages by topic, sending each message to the Subscribers who have subscribed to each Topic [12] [17] [53] [54] [56] [57].…”

“…Developers consider reference architecture to be the cornerstone of their work since it allows them to map their work to a guiding model; so, what are the key functions that architecture should provide, and who are the major players involved in a structure to make it consistent and sustainable? [50] [65] In its most basic form, an IoT system architecture should enable the transmission of data from Things, which are essentially sensors, to the cloud over a network, as well as the transmission of commands or instructions derived from processing and analyzing the stored data to actuators, which represent the parts that allow the system to respond to its environment [8] [57].…”

“…Gubbi et al introduced the 3-layers design in 2013, which is considered the most straightforward architecture among the others because it is made up of three layers and the majority of IoT architectural research starts here [57] [69].…”

“…The components of this model are organized into three layers (Figure 4(a)) [13] Advances in Internet of Things [42] [51] [57] [60] [69] [70]:  The perception layer represents sensors, actuators, and other edge devices, or "things", this layer is in charge of tying the whole structure together with its surroundings.  The Network layer sits on top of the Perception layer, allowing items to be extended by connecting them to other objects such as software, network devices, and servers.…”

The Internet of Things (IoT) is a technological revolution that has changed everything we do and given us a new perspective on our daily lives, but despite the fact that numerous publications have focused on characterizing the many edges and technologies that make up an IoT system, the IoT ecosystem is still seen as too complex to be recognized as a stand-alone environment due to its significant diversity; hence, the objective of this research is to address such a complex environment in a way that highlights its components and distinguishes them both individually and in relation to their broader context. Therefore, the definition of IoT and its emergence were discussed and organized around the timeline of Internet development phases demonstrating that IoT has been a need that has accompanied the presence of the Internet since its early stages, and then its growth and impact were discussed and highlighted with estimates and numbers. On the technical side, each of the following groups, IoT components, protocols, and architectures, was defined, discussed, and grouped in such a way that their intergroup organization, as well as their placement and contribution to the overall ecosystem, was highlighted. This, in addition to the various examples mentioned throughout the discussion, will provide the reader with a better understanding of the Internet of Things and how deeply it has become entwined in our daily lives and routines as a result of its numerous applications.
