Introduction to Wireless (WiFi)
Mesh Network
What is WiFi Mesh Network?
A collection of wireless devices maintaining RF connectivity to create a
seamless path for data packets to travel.
– At least one wireless device (or node) is connected to a wired Internet backbone
and each data packet is bound for the same destination but not necessary using
the same sequential path of nodes.
The Internet router determines a path between the user and the physical
– In the wireless mesh environment, a network can be envisioned as a collection of
access points, routers, or end users (equipped with wireless receiver/transmitters)
that are free to move arbitrarily but maintain a reliable communication that sends
and receive messages.
A semi-mobile system
– the connectivity position among the nodes may vary with time due to node
departures, new node arrivals, and roaming nodes
Combining at least two P-to-P or P-to-MP wireless cells create a roaming
– Roaming is the ability to maintain network connectivity while moving from one
access point to another

WiFi Mesh Network – Solving Coverage
Vehicular networks
Combat the awful side-effects of road traffic
– In the EU, around 40’000 people die yearly on the roads; more than 1.5
millions are injured
– Traffic jams generate a tremendous waste of time and of fuel
Most of these problems can be solved by providing appropriate
information to the driver or to the vehicle
Vehicular networks
The way
is clear
• All automakers are working on vehicular comm.
• Vehicular networks will probably be the largest incarnation of mobile Mesh
A Wireless Mesh Network constructed from WiFi Technology
alleviate a number of roaming challenges from laptops, IP phones,
PDAs, and IP base devices:
– No geographical limitations – User can take a handheld or laptop
computer anywhere without losing the connection in their home
– No physical connection required – Mobile IP connect automatically
and obtain local IP router information
– Supports security – Authentication is performed to ensure that rights
are being protected
– Access Anytime, Anywhere – Network access is assured at all times
and from all locations. No missed E-mails and increase productivity
due to constant connectivity.
– Emergencies – Rapidly deployable and robust communications
between each member when emergencies are involved in difficult
operations inside buildings, towers, or surrounded in forest fires
– Military Usage – Soldiers in a battlefield are exchanging information
about their position and giving and receiving orders, or the
