What is Mesh Networking?
Mesh networking 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.
WMN Architecture Classifications
WMesh networking is typically implemented in two basic modes: infrastructure and/or client meshing. To gain the maximum benefit that meshing can offer, both modes need to be supported simultaneously and seamlessly in a single network.
Infrastructure Meshing
Client WMNs
Hybrid WMNs
WMNs Characteristics
Advantages of WMN
Application Scenarios
Broadband Home Networking
Current home network realized through IEEE 802.11 WLANs
Metropolitan Area Networks
WMNs provide higher transmission rate than cellular networks,
The communication between nodes does not rely on a wired backbone.
Transportation Systems
WMNs can extend access from stations & stops into buses, ferries, & trains.
Two key techniques are needed
High-speed mobile backhaul from a vehicle to the Internet
Mobile mesh networks within the vehicle.
Health and Medical Systems
Monitoring and diagnosis data need to be processed and transmitted across rooms for various purposes.
Large data volume by high resolution medical images, various periodical monitoring information
Wi-Fi based networks must rely on the existence of Ethernet connections, cause high system cost, complexity and dead spots.
However, these issues do not exist in WMNs.
Community and Neighborhood Networking
Community networks based on cable, DSL and last-hop wireless
Enterprise Networking
IEEE 802.11 WLANs
Isolated islands, connections among them are achieved through
wired Ethernet
