Internet of Things (IoT) and wireless sensor networks (WSN) are commonly confused. We’ll explain the two concepts with examples and will discuss the difference between Wireless Sensor Networks (WSN) and IoT in this article.
One of the most fascinating technologies is the Internet of Things (IoT). It affects our interactions with technology and social interactions. Other sensor network-related technologies are also becoming prominent. A wireless sensor network is one of the key. One of the main technological will discuss the components of Internet of Things is wireless sensor network.

IoT deployment requires the use of wireless sensor networks. Wireless sensor networks integrate IoT devices locally, whereas the Internet of Things connects the real world to the web.
Wireless Sensor Network
Wireless sensor network (WSNs) are ad hoc networks of autonomous devices that collect information from the physical environment. It includes cluster of sensor networks, mesh networks, field area networks (FANs), body area networks (BANs) and narrowband IoT (NB-IoT).
These low-powered devices need certain communication protocols to transfer data. IoT systems collect and analyze data from each autonomously linked device. Private cloud providers offer limited storage and applications, while public cloud providers serve all customers.
Example: Wireless Sensor Network
One example of a WSN is a network of sensors on a ship’s hull to detect water intrusion. Each sensor has a unique ID and operates independently. Each sensor is battery-powered which sends data to a central gateway using an ultralow-power protocol. The gateway aggregates data collected from the sensors before sending it to the IoT platform.
A network of nodes used for infrastructure management is another example of a WSN. They have improved the efficiency and convenience of people’s lives.

Internet of Things
A network of interconnected devices that can interact via the internet and can communicate with each other is known as the Internet of Things (IoT). Anything from cellphones to home appliances can be included in these devices. The devices may send and receive data since they are online and connected. The information can then be used to control devices or provide user information.
All of the sensors in an IoT system send data directly to the internet.
Example: Internet of Things
A sensor might be used, for example, to monitor the temperature of a body of water. The data will be instantly or repeatedly sent directly to the internet, where a server can process it and allow for front-end interface interpretation.

WSN as an IoT Subset
WSN is a technology that is frequently used in IoT systems. In an IoT system, a large collection of sensors, like those in a mesh network, can be used to collect data on their own and transfer it via a router to the internet.
It’s also crucial to remember that “the internet of things” encompasses far more than the term “wireless sensor network.”

WSN is a network made up entirely of wireless sensors. A wired sensor would prevent the network from still being referred to as a “wireless sensor network.”
IoT is not like this. IoT devices may essentially be any device that connects to the internet. As a result, a “IoT system” can be thought of as a collection of numerous IoT devices.

Difference Between Wireless Sensor Networks (WSN) and the Internet of Things (IoT)
- WSNs are used to track and gather information about physical or environmental conditions.
In contrast, the IoT is a technology that links hardware to the internet so that it can communicate with other devices and share data. - WSNs are frequently made to function in certain settings for a particular need. In contrast, the IoT is intended to be more general and versatile.
- In challenging or hazardous situations, WSNs are frequently utilized for monitoring purposes.
While the IoT is used to connect multiple devices and objects in in more everyday settings. - While the IoT relies on industry-standard protocols like TCP/IP, WSN frequently use proprietary technologies and protocols.
- IoT typically consists of a smaller number of devices that are connected to the internet via wired or wireless connections, whereas WSN typically consist of a large number of small, low-power sensors that wirelessly transmit data to a central base station.
- While the IoT is more dynamic, with devices and things being moved around and connected to multiple networks. WSNs are often static, with sensors being put in a specific location and remaining in that location.
- A single organization typically deploys and operates WSN. The IoT, on the other hand, is more decentralized and involves many organizations and people.
- IoT is more open, where data is shared and utilized by a range of organizations and individuals, WSNs are frequently closed systems with data being collected and used by the deploying organization.
- Data collection and monitoring generally involve WSN. Whereas the IoT can be used for a number of purposes, such as data gathering, monitoring, control, and communication.
- IoT market is more developed, the WSN market is still emerging.

Internet of Things vs Wireless Sensor Networks
| Basis | Internet of Things | Wireless Sensor Network |
|---|---|---|
| Protocols | In NetSim IoT, the AODV and RPL routing protocols are used. | The NetSim WSN uses DSR, AODV, OLSR, and ZRP routing protocols. |
| Architecture | IOT has a gateway that can connect to internetworks (having routers, switches, APs, etc.) | WSN is a network of only sensors. |
| Devices | IOT uses IPv6 in the sensor network (802.15.4 MAC/PHY) and IPv4 on the internetwork portion. | WSN uses IPv4 and includes a sink (not a gateway). |
