Every node not only
captures and disseminates its own data, it also serves as a relay for
the other nodes. Mesh networking is a type of networking that needs
collaboration for propagation. A mesh network is designed using
either, a flooding technique or a routing technique. The latter is when
the message propagates along a path by hopping from one node to another
until the destination is reached. And to make sure that all of the paths
are available, a routing network using self-healing algorithms should
allow continuous connections and reconfiguration around broken or
blocked paths. This self-healing capability enables a routing based
network to operate when one node breaks down or gets disrupted. As a
result, the network is usually reliable since there is often more than
one path between a source and a destination in the network.
The self-healing capability concept can also be used to wired networks
and software interaction, although it is usually for wireless
scenarios. Wireless mesh networks were originally developed for military
applications and usually of mesh architectures. However, on the next
years after that, the size, cost and power requirements of radios
declined causing more radios top be included within each device acting
as a mesh node. The additional radios then within each node enable it to
support multiple functions, like access, backhaul service, and scanning
which requires a high speed handover in mobile applications.
Additionally, the reduction in radio, size, cost and power enabled the
mesh nodes to be more modular. One node or device can now contain
multiple radio cards or modules, allowing the nodes to be customized to
handle a unique set of functions and frequency bands. Work in this
field has been relieved by the use of game theory methods to analyze
strategies for the allocation of resources and routing of packets. Game
theory is a mathematical method for analyzing calculated circumstances,
such as in games, where a person's success is based upon the choices of
others. Mesh networks can also be seen as a kind of ad hoc network,
-œfor this purpose,- a self-configuring infrastructure-less network of
mobile devices connected by wireless links.For more info,Please visit meraki
This and mesh networks are therefore closely related, although MANET
also has to deal with the problems brought by the mobility of the nodes.
A mesh network having nodes connected to each other is a
fully-connected network. In early 2007, the US-based firm Meraki
launched a mini wireless mesh router, an example of a wireless mesh
network on a claimed speed of up to 50 megabits per second. The 802.11
radio within the Meraki Mini has been optimized for long-distance
communication, providing coverage of over 250 m, an example of a
single-radio mesh network being used within a community as opposed to
multi-radio long range mesh networks like BelAir or MeshDynamics that
provide multifunctional infrastructure.
