Mesh networking. Illustration of a mesh network.
A mesh network can be designed using a flooding technique or a routing technique. When using a routing technique, the message is propagated along a path, by hopping from node to node until the destination is reached. To ensure all its paths' availability, a routing network must allow for continuous connections and reconfiguration around broken or blocked paths, using self-healing algorithms. Power over Ethernet. Given a single Power over Ethernet connection (single gray cable looping below), a PoE splitter provides both data (gray cable looping above) and power (black cable also looping above) connections for a wireless access point.
The splitter is the silver and black box in the middle, between the wiring box on the left and the access point (with its two antennas) on the right. The PoE connection eliminates the need for a nearby power outlet. Power over Ethernet or PoE describes any of several standardized or ad-hoc systems which pass electrical power along with data on Ethernet cabling. This allows a single cable to provide both data connection and electrical power to devices such as wireless access points or IP cameras. Unlike standards such as Universal Serial Bus which also power devices over the data cables, PoE allows long cable lengths.
Wireless mesh network. Diagram showing a possible configuration for a wireless mesh network, connected upstream via a VSAT link (click to enlarge) History[edit] Network structures[edit] Architecture[edit] Wireless mesh architecture is a first step towards providing cost effective and dynamic high-bandwidth networks over a specific coverage area. Wireless mesh architectures infrastructure is, in effect, a router network minus the cabling between nodes. Wireless mesh networks have a relatively stable topology except for the occasional failure of nodes or addition of new nodes. B.A.T.M.A.N. The Better Approach To Mobile Adhoc Networking (B.A.T.M.A.N.) is a routing protocol for multi-hop ad hoc mesh networks which is under development by the "Freifunk" community and intended to replace OLSR.
In early 2007 the batman developers started experimenting with the idea of routing on layer 2 (Ethernet layer) instead of layer 3. To differentiate from the layer 3 routing daemon the suffix "adv" (spoken: advanced) was chosen. Instead of sending UDP packets and manipulating routing tables, it provides a virtual network interface and transparently transports packets on its own. The batman-adv kernel module is part of the official Linux kernel since 2.6.38. [1] Operation[edit] B.A.T.M.A.N. does have elements of classical routing protocols: It detects other B.A.T.M.A.N. nodes and finds the best way (route) to these. In static networks, network administrators or technicians decide which computer is reached via which way or cable. History[edit] Version one[edit] Version two[edit] See also[edit] IEEE 802.11s. IEEE 802.11s is an IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create a WLAN mesh network, which may be used for static topologies and ad hoc networks. 802.11 is a set of IEEE standards that govern wireless networking transmission methods.
They are commonly used today in their 802.11a, 802.11b, 802.11g, and 802.11n versions to provide wireless connectivity in the home, office and some commercial establishments.
