Architectural design of Wireless mesh Network Wireless mesh network consisting of a network having mesh routers not connected with the help of the cables. It’s constructed of noble radio devices that don’t need to be connected by cable to a wired port as it is done in existing access point in case of wireless network. In mesh network data are carried through a big distances by dividing the distances into small pieces of small hops. Based on the information of the network available to the intermediate nodes it boosts the signal and transmits the towards the destination from the source. i.e. achieve routing by initially by deriving the network topology.
The architecture in WMNs can be categorized in three different classes depending on the functions of their nodes:
- Client Wireless Mesh Networks
- Hierarchical Wireless Mesh Network
- Hybrid Mesh Networks
Client Wireless Mesh Networks
In client WMN, the network is made up of only client devices, where they act both as routers and hosts. In this network the level of every nodes are same and they synchronize between them so that they are able to offer configuration of networks, finding route, other service and application provisioning. It is the simplest architecture amongst all the three variations of WMNs architecture and is somehow nearly similar to ad hoc wireless network. One of the basic benefits of this architecture simplicity while lack of scalability in the network and higher constraints on the resources. The main challenges in the design of client wireless mesh networks are the addressing system, routing, and service detection systems. Out of which the addressing system is the most challenging part that provide bottleneck against scalability. The basic architecture is shown in figure.
