MESH TOPOLOGY
Mesh Network is a network where all the nodes are connected to each other and is a complete network. In a Mesh Network every node is connected to other nodes on the network through hops. Some are connected through single hops and some may be connected with more than one hope. It also
A type of network setup where each of the computers and network devices are interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. This type of topology is not commonly used for most computer networks as it is difficult and expensive to have redundant connection to every computer. However, this type of topology is commonly used for wireless networks.
A wireless mesh network is made up of two or more wireless access points, working in harmony with each other while sharing each other routing protocols, in a collection of cross-connect links to create an interconnected electronic pathway for the transmission between two or more computers. When a wireless mesh is form it creates a single name identifier for access and the signals between wireless access points are used with each other to clearly distinguishable from another network. The organization of sharing access points working in harmony is known as the mesh topology. The defined mesh topology of a given area defined by the access points is known as mesh cloud. Access to this mesh cloud is dependent on the network created by the access points.
There are three types of mesh networks
a.Fixed wireless installations that connect multiple locations using Ad-hoc mode
b.Mobile, peer-to-peer, ad-hoc networks that have variable availability and a potentially ever changing set of nodes and finallyc.Node-to-node infrastructure network that connect multiple locations and combine with mobile giving the best of the both world.
Fixed mesh networks are generally built with the expectation that many nodes have no direct backhaul, network, or Internet access. In fact, if each location had some kind of enterprise or Internet access, distributing service by wireless would be almost unnecessary.
In a fixed installation, locations for nodes are chosen with an eye for providing the right overall level of bandwidth with the fewest points. Fixed mesh networks also can effectively offer non-line-of-sight service by ringing an obstacle -- a tall building, a hill, a cluster of trees, an area of known interference -- with enough nodes to bypass it. These fixed networks are typically directional enough over each link to avoid major security risks.
In contrast, peer-to-peer mobile mesh networks -- which are a long way from actual deployment -- rely on individual devices connecting to each other through devices within radio range. Scalability can be an is
