2.  The term ‘mesh networks' describes wireless networks in
which each node can communicate directly with one or more
peer nodes.
 Wireless mesh networks (WMNs) are regarded as an
economical alternative key technology for next generation
wireless networking.
 Wireless mesh networks can easily, effectively and wirelessly
connect entire cities using inexpensive,existing technology.

3.  Wireless mesh networks (WMNs) are dynamically self
organized and self-configured and they are comprised of two
types of nodes:
I. Mesh routers
II. Mesh clients.

4. 1) INFRASTRUCTURE MESHING
2) CLIENT MESH NETWORKING
3) HYBRID MESH NETWORKING

5.  This includes mesh routers that form an infrastructure for
clients that connect to them.
 This can be built using various types of radio technologies
 With gateway functionality, mesh routers can be connected to
the Internet.

6.  For example, community and neighborhood networks can be built
using infrastructure meshing.
 The mesh routers are placed on the roof of houses in a
neighborhood, which serve as access points for users inside the
homes and along the roads.
 Typically, two types of radios are used in the routers, i.e., for
backbone communication and for user communication,
respectively.

8.  Client meshing provides peer-to-peer networks among client
devices.
 A mesh router is not required for these types of networks.
 A packet destined to a node in the network hops through
multiple nodes to reach the destination.
 Moreover, the requirements on end-user devices is increased
when compared to infrastructure meshing; the end-users
have to perform additional functions such as routing and
self-configuration.

10.  This architecture is the combination of infrastructure and
client meshing.
 Mesh clients can access the network through mesh routers as
well as directly meshing with other mesh clients.
 While the infrastructure provides connectivity to other
networks such as the Internet, Wi-Fi, WiMAX, cellular, and
sensor networks; the routing capabilities of clients provide
improved connectivity and coverage inside the WMN.
 The hybrid architecture will be the most applicable case!!!

12.  Fewer wires -> less cost to set up a network
 More nodes -> bigger and faster wireless networks
 Same WiFi standards (802.11a, b and g)
 “Self configuring" networks
 “Self healing" networks
 Wireless mesh configurations allow local networks to run
faster local packets don't have to travel back to a central
server.

13.  Price: 802.11 radios are quite cheap, but the radios are often
still expensive
 Ease and simplicity
 Organization and business models:
 Integration
 Power

14.  Scalability
 Mesh Connectivity
 Broadband and QoS
 Compatibility and Inter-Operability
 Security
 Ease of Use

15.  Health and Medical Systems:
 Security Surveillance Systems:
 Building Automation
 Transportation Systems:
 Broadband Home Networking
 Warehouses
