Advantages and Disadvantages of Mesh Topology

Mesh topology is a type of network topology in which every node is connected to every other node in the network. This topology provides a high level of redundancy and error tolerance, making it a popular choice for large-scale networks. However, the major disadvantage is it is costly because it consumes a lot of wires to connect it’s like connecting n-size mesh requires $\mathrm{n_{c_{2}}}$. In this article, we will discuss the advantages and disadvantages of Mesh topology.


  • High Reliability − Mesh topology offers a high level of reliability, which is one of its biggest advantages. There is no single point of failure, if one node fails, the network still functions as long as there are other paths available. This redundancy ensures that the network stays up and running even if some nodes are down. This makes mesh topology an ideal choice for critical applications that require, the availability of the network all the time.

  • Scalability − Mesh structure is very trustworthy. By connecting new nodes to the current nodes, mesh networks can be easily expanded. Due to this, it is a great option for big sales networks that must support a lot of devices. Small networks can also use mesh topology, but because so many links are needed, it might not be as cost-effective.

  • Security − High-security levels are provided by mesh structure. There are numerous paths for data to move because every node is connected to every other node. Because of this, it is challenging for attackers to intercept or eavesdrop on network data. To further improve the security of the network, mesh topology also enables the use of numerous security measures like encryption and identification.

  • Fault Isolation − Mesh topology facilitates fault separation. If one of the nodes fails, the remaining nodes of the network can continue functioning consistently. And the not working node can be identified and replaced.

    This makes it easier to maintain the network and ensures that it remains trusty and available.

    Furthermore, the fault isolation feature is particularly useful in applications where network downtime is unacceptable, such as in critical infrastructure, healthcare, or financial services. The ability to quickly identify and replace a failed node makes sure that the network remains available and functional, which is essential for these missions.

  • High Performance − High speed is provided by mesh topology. Data can be transmitted effortlessly and quickly because every node in the network can communicate directly with each other. Because of this, a mesh topology is a great option for apps like multiplayer gaming and viewing videos that demand fast data transfer rates.


  • Complexity − Mesh topology is complex because every node is having a connection with all other nodes which consumes a lot of time. In a small network, it’s okay to maintain, but as the network size grows, the number of devices connected to it or router connected to it grows then it would be very difficult to maintain. And keep up to date. That’s why this method of connecting networks is comparatively complex concerning other topologies.

  • High Cost − This is a measure issue of mesh topology because it costs more because it takes all way wires one node is connected to (n-1) other nodes. An n-1 connection is required so for n nodes n_(C_2 ) connections. This is the reason for the high cost.

  • Limited scalability − Such topologies are difficult to scale when a big setup with mesh topology is created then, to add one node we have to connect all the available nodes which means n connections we have to make. And this cost a lot with so much effort as the network grows.

  • Redundancy − While redundancy is a key advantage of mesh topology, it can also be a disadvantage. Mesh topology requires a larger number of connections between nodes. Which can result in a high level of redundancy.

  • Bandwidth Issues − Mesh topology can suffer from bandwidth issues. This is because data must go through multiple nodes to reach its destination. this can result in slower network speeds and increased congestion. However, this can be mitigated by using speed connections between nodes and implementing quality-of-service measures to prioritize network traffic.


Mesh topology has many benefits, including high speed, scalability, security, and fault isolation. It does, however, have some drawbacks, such as high expense, complexity, bandwidth problems, constrained scalability, and redundancy. One area where mesh networks may see increased adoption is in the Internet of Things (IoT), where a large number of connected devices require reliable and robust network connectivity.

Mesh topology's ability to support a large number of nodes and provide redundancy and fault tolerance could make it a popular choice for IoT deployments. As technology continues to advance, it will be interesting to see how mesh topology evolves to meet the demands of this rapidly growing field.
