What is a Mesh Network?

In the field of Computer Networks, a Mesh Network is one of the revolutionary concepts for communication and data transmission in a set of various nodes. The Mesh Network is a decentralized communication system that is used for data transmission and data collection In this approach the nodes are directly connected, where there is the dynamic web interconnections among them, and the transmission takes place. In this article, we will go through the detailed concept of Mesh Network.

What is a Mesh Network?

A mesh network is a network in which devices — or nodes — are linked together, branching off other devices or nodes. These networks are set up to efficiently route data between devices and clients. They help organizations provide a consistent connection throughout a physical space.

Mesh network topologies create multiple routes for information to travel among connected nodes. This approach increases the resilience of the network in case of a node or connection failure. Larger mesh networks may include multiple routers, switches, and other devices, which operate as nodes. It can include hundreds of wireless mesh nodes, which allows it to span a large area.

How does it work?

Mesh networks rely on network nodes, which are the connection points among network devices. These devices include routers, printers, and switches that can send data from one point to another.

In a mesh network, every node is connected to every other node. They give multiple sources for a device to connect to rather than just a single router. Mesh networks provide a web, or ‘mesh,’ of wireless network connections that completely cover the area within its mesh nodes.

It is very common in homes and office buildings where a high-quality connection throughout a building or place is important.

The benefits of a mesh network

• Increased stability. Single points of failure don’t harm the whole network.
• Increased range. It can transmit signals over a greater distance. They have fewer dead spots where Wi-Fi signals don’t reach.
• Direct communication. Nodes can message each other directly. There is no need for intervention from a central access point.
• Less power is needed for each node. Each device in the network doesn’t need to put out a signal strong enough to reach a central access point.
• Better security. If attacked, single nodes are easily replaced.
• Simpler topology. It requires less infrastructure than other types of network configurations.

Disadvantages of Mesh Network

• Less Cost Efficient. As compared to other networks the mesh network is less cost effective. It costs more as the devices are interconnected in the networks.
• Overhead Installation. In the mesh network, there are various nodes, and each node or device is connected to the other node in the same network. So due to this, the paths or shouts become more in the initial phase. The installation becomes complex and extremely difficult for the administrator.
• Difficult Maintenance. Maintenance as compared to other networks is challenging in mesh networks, as there are various nodes. And each node is connected to another node with various parts. So due to this, the maintenance of each path becomes complex.
• Power Requirement. The needle power requirement is slightly higher in this mesh network because all the nodes that are connected in the structure remain active all the time and share the data or load in case of load balancing.

Mesh Network vs Traditional Networks

Mesh networks connect the infrastructure nodes in an easy, effective, and wireless way, using inexpensive, existing technology. It makes every object in IoT become possible.

Traditional networks connect users and devices counting on a small number of wired access points or wireless hotspots. In the wireless mesh network, the network connection stretches among dozens or hundreds of wireless mesh nodes that communicate with each other to share the network connection across a large area.

Mesh works in a different way. There’s no central hub, switch, or computer which handles all computer traffic. Instead, each device on the mesh network can talk to every other device. It uses a particular kind of protocol for moving information from one place to another. These multiple relays can quickly direct traffic across devices. This creates a mesh-like pattern of connectivity.

Mesh networking examples

• Home mesh Wi-Fi systems: These systems use multiple wireless access points or nodes to provide seamless Wi-Fi coverage throughout a home, eliminating dead zones and improving network performance.
• Community mesh networks: Grassroots initiatives that create community-owned networks to provide internet access to underserved areas or promote digital privacy and net neutrality.
• IoT mesh networks: Wireless mesh networks that connect IoT devices and sensors, enabling efficient data collection and communication in smart homes, industrial automation, and environmental monitoring.

Conclusion

In conclusion, mesh networks are an ideal infrastructure for IoT projects, as they provide additional flexibility by allowing them to operate regardless of broken paths or faulty devices. It is bound to become more and more practical, completely making the IoT era march forward. The future applications for wireless mesh networks are limited only by our imaginations.
