Wireless mesh network provides stability when compared to the rest of the network topologies rather than the node addition or deletion in the network. In infrastructure mesh network, the data forwarding and receiving are via gateway, whereas in

The frequency of link breakage is higher in the case of wireless mesh networks when there is a high mobility which results in low performance in communication

Wireless mesh networks are categorized into three types based on the function-

Mesh routers together act as a wireless back bone for infrastructure mesh architecture. Client node is passive in mesh infrastructure via Ethernet links; conven-

If the traditional network and the mesh router are operating under the same radio range, then it is easy for the mesh network to communicate with the mesh router. Alternatively, if the radio ranges differ, the nodes will communicate to the base station so that with the help of Ethernet, it can be further communicated to the mesh routers. **Figure 1** shows the mesh architecture for infrastructure-based network.

Mesh architecture based on client is the one in which the client nodes are connected from peer to peer. Each node can act as a routing node to transfer the data. Here, the client performs the role of mesh routing by acting in the forwarding of the data packets.

tional clients with Ethernet interfaces can be connected to mesh routers.

In hybrid mesh architecture, usually the mesh nodes/router acts as a back bone of the entire network operation. With the help of network mesh router, it performs routing and forwarding of data packets toward its destination [5] which is shown in **Figure 3**.
