What is Mesh Networking???
Mesh networking (topology) is a type of networking where each node must not only capture and disseminate its own data, but also serve as a relay for other sensor nodes, that is, it must collaborate to propagate the data in the network.
A mesh network can be designed using a flooding technique or a routing technique. When using a routing technique, the message propagates along a path, by hopping from node to node until the destination is reached.
A mesh network whose nodes are all connected to each other is a fully connected network. Mesh networks can be seen as one type of ad hoc network.
Mobile ad hoc networks (MANET) and mesh networks are therefore closely related, but MANET also have to deal with the problems introduced by the mobility of the nodes.
Internet is a Mesh Network
MAN as Mesh Network
Mesh networks were originally developed for military applications and are typical of mesh architectures.
Over the past decade the size, cost, and power requirements of radios has declined, enabling more radios to be included within each device acting as a mesh node.
Nodes can be customized to handle a unique set of functions and frequency bands.
Devices Used
MeshBox is an item of computer hardware which is used to provide large scale wireless broadband networks. Manufactured by LocustWorld, the devices are designed to co-operate with other MeshBoxes within range, passing the internet service from one box to the next, over the air, until it reaches the final destination. The coverage area of a mesh is typically measured in square miles.
Meraki
Meraki is a wireless networking company that provides hardware and software for building large scale wireless networks. These networks are used by businesses, schools, and other organizations that need several access points or have multiple sites. It uses a centralized control system hosted on Meraki's servers.
Applications
There are various applications of mesh networks like
Wireless mesh network
BioWeb
Wireless ad hoc network
Mobile ad hoc network (MANET)
Vehicular ad-hoc network
Intelligent Vehicular AdHoc Network
Wireless Mesh Network
A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. Wireless mesh networks often consist of mesh clients, mesh routers and gateways.The mesh clients are often laptops, cell phones and other wireless devices while the mesh routers forward traffic to and from the gateways which may but need not connect to the Internet.
Vehicular Ad hoc Network
A Vehicular Ad-Hoc Network, or VANET, is a technology that uses moving cars as nodes in a network to create a mobile network.
VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range.
As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes.
