Advantage and Disadvantage of Mesh Topology

Prerequisite – Types of Network Topology

Mesh Topology :

In mesh, all the computers are interconnected to every other during a network. Each computer not only sends its own signals but also relays data from other computers. The nodes are connected to every other completely via a dedicated link during which information is travel from nodes to nodes and there are N(N-1)/2 links in mesh if there are N nodes. Every node features a point-to-point connection to the opposite node. The connections within the mesh are often wired or wireless.

There are two types of Mesh topologies –

1. Fully-connected Mesh Topology
2. Partially-connected Mesh Topology

1. Full Mesh Topology :

All the nodes within the network are connected with every other If there are n number of nodes during a network, each node will have an n-1 number of connections. A full mesh provides an excellent deal of redundancy, but because it is prohibitively expensive to implement, it’s usually reserved for network backbones.

2. Partial Mesh Topology :

The partial mesh is more practical as compared to the full mesh. In a partially connected mesh, all the nodes aren’t necessary to be connected with one another during a network. Peripheral networks are connected using partial mesh and work with a full-mesh backbone in tandem.

Advantages of Mesh Topology :

• Failure during a single device won’t break the network.
• There is no traffic problem as there is a dedicated point to point links for every computer.
• Fault identification is straightforward.
• This topology provides multiple paths to succeed in the destination and tons of redundancy.
• It provides high privacy and security.
• Data transmission is more consistent because failure doesn’t disrupt its processes.
• Adding new devices won’t disrupt data transmissions.
• This topology has robust features to beat any situation.
• A mesh doesn’t have a centralized authority.

Disadvantages of Mesh Topology :

• It’s costly as compared to the opposite network topologies i.e. star, bus, point to point topology.
• Installation is extremely difficult in the mesh.
• Power requirement is higher as all the nodes will need to remain active all the time and share the load.
• Complex process.
• The cost to implement mesh is above other selections.
• There is a high risk of redundant connections.
• Each node requires a further utility cost to think about.
• Maintenance needs are challenging with a mesh.

What is Mesh Topology? Advantages and Disadvantages of Mesh Topology

With the help of mesh topology, we have been able to achieve a full or partial connection. In case of a complete connection, all computers are connected, and we can calculate the number of connections with a specific formula. If there is a partial connection, then at least two of the computers will connect to multiple devices. It is an excellent way to implement primary connections without worrying about any computer failing to operate and disrupting the connection. Here are the advantages and disadvantages of mesh topology.

Advantages of Mesh Topology

There are several advantages of Mesh Topology, and learning about these can help you decide how to set up the network and benefit from it.

1. Mesh Topology can manage a high level of traffic: Mesh Topology does not have a hierarchical relationship. Suppose any device is connected to it and attempts to contact any other one by directly taking advantage of the routing ability of the devices. In that case, they will be able to do it.
2. Failure of one single device does not affect thenetwork: Mesh topology is exceptional when it comes to being resistant to problems. Each node of the network receives and translates information. The structure provides its users with a sufficient level of redundancy so that they can keep it running even if some malfunctions occur. If one node goes down, the network has the strength to use the other ones and complete the mesh.
3. Data transmission is consistent since failure in the network does not disrupt the process: Multiple paths for data transmission are available in Mesh Topology. It requires each node to be connected to all the other ones so that the network can create a successful set of ways to operate. As a result, the overall data transmission is more consistent. Furthermore, multiple node failures do not affect the pathway and can still send a message.
4. Adding new devices does not affect data transmission: Mesh Topology’s structure enables users to add new widgets to add new devices without disrupting the messages that were occurring at that time. Since every node is connected, a breakdown in one of the equipment will not disrupt the flow of information.
5. Scalability is simple:Mesh topology does not require additional routers since each node acts as an individual router that allows one to change the size of the network comfortably. Hence, one can easily add new technology to any room in a corporate situation at the current speed of operation temporarily.
6. Easy to add mesh topology:Usually, adding Mesh Topology is easy and goes about without any problem. One needs to connect the nodes to the gateways so that the messages can pass through to the remaining network for it to work. It allows the technology to become self-optimized.
7. Taking down the network is nearly impossible:The modern structure of Mesh Topology in the world means that it is almost impossible to take it down unless there is a global disaster where all the devices we use around the globe get wiped out.
8. There is no need for a centralized authority:Mesh topology does not need to incorporate a centralized control to send data. Hence, one set up an individual-based secure method of communication that lets them have the option to be anonymous if desired. They don’t need to run a firewall or other such software solutions to maintain their privacy.
9. Flexible:The Mesh Topology has immense flexibility due to its partial shortfall option. Therefore, one is not forced to have a complete set of connections for each node, but the network can be built with a partial web to take advantage of the enhanced communication.
10. It can manage a massive volume of data:A network with Mesh Topology can handle a tremendous volume of data compared to traditional systems since it is possible to connect multiple devices at a time and transmit data simultaneously.

Disadvantages of Mesh Topology

Though Mesh Topology has many advantages, there are some disadvantages. Knowing these can help one to understand the flip side of the coin. The disadvantages are as follows.

1. High cost:The cost for implementing Mesh Topology is higher than others due to the requirement of several parts of equipment that is quite extensive. It cannot operate correctly until you have all the hardware, cabling, internet bandwidth, etc., necessary for the installation.
2. Time-consuming to build and maintain:Once it is operational, adding new nodes is simple, but the initial process is complex and time-consuming.
3. High risk of redundant connection:Since Mesh Topology can handle a large number of networks, there is a chance of setting redundant connections.
4. Each node has an increased workload:The nodes have many responsibilities, and each one must act as a router. Hence, the system is very complex.
5. Latency issues:Low power Mesh Topology does not have the processing capacity to handle data transfers in a timely manner. Hence there are plenty of latency issues.

Question 3.
Why are the nodes essential for mesh topology?

Answer:
The potential node distribution points in a building or other areas are an essential factor because there aren’t enough nodes, then linkage problems may occur while processing the messages.

Mesh networks

In a mesh topologythere is no central connection point. Instead, each nodeis connected to at least one other node and usually to more than one. Each node is capable of sending messages to and receiving messages from other nodes. The nodes act as relays, passing on a message towards its final destination.

There are two types of mesh topology:

• full mesh topology
• partial mesh topology

Mesh networks are becoming increasingly popular due to their efficiency.

With a full mesh, each node is directly connected to every other node. This enables a message to be sent along many individual routes.

How does the Mesh topology Work

To understand in detail the procedure of mesh topology, let us first discuss the usual process of the network connection. Commonly, all the devices, Computers, routers connected in usual network connection like the end to end connection, router to the server, and vice versa.

A Single Server connected to different client servers, hosts, and remote users. Where in Mesh Network, the connection is quite different from the usual network connection.The devices in a network connected to all the other networks in a Device. The Devices also be known as nodes or Hosts in a network.

This Nodes or devices send data to the other nodes within the range. The data moves from one node to the other node until it reaches its destination device. These devices or nodes can send the data in many forms as long as it attains the correct destination node. The connection to these nodes is connected through the wireless routers, similar to the network we use at home.

However, Mesh topology should behave differently than the common internet connection. The Mesh Topology not only sends the data from sender to receiver but also find the efficient path to transmit the data. The Devices who accomplish this process is called the Routing protocol.

A Routing protocol is a set of rules coded into the nodes that use a global or local plan to find the efficient path from the sender to the receiver.

It uses various protocols and algorithms to find the best path to end the data from the sender to the receiver. OLS, HWMP algorithms are used to forward the data around the mesh. These data create network traffic that sometimes influences the data congestion in the topology.

The Mesh Topology is used to share the network connection. Nevertheless, Many of the Mesh networks doesn’t involve a Large internet connection. The Mesh networks use their servers to transfer the data. Due to the utilization of their own servers, the users can communicate and exchange information within the Mesh network connection. There is no need the use larger network connections

The Mesh topology has many properties and algorithms to obtain an efficient path and performance

• The Mesh Network is also called self-healing as it finds multiple ways to transmit the data across the mesh topology. It finds its path as long as the network functions.
• These are self-discovering and configuring, When new nodes enter into the mesh network, it automatically integrates these nodes. The transmission path of these nodes is inexpensive. These nodes are built with wireless routers which are very inexpensive.
