Wireless mesh networks are self-organizing networks that can connect entire cities using existing wireless technology in an economical way. They are comprised of mesh routers that form the infrastructure and connect to the internet, and mesh clients that can access the network through the routers or directly connect with other clients. The hybrid mesh architecture combines infrastructure and client meshing to provide improved connectivity inside the network. Wireless mesh networks offer benefits like lower setup costs, larger network size, and self-configuration, but also face challenges regarding scalability, compatibility, and security. Potential applications of wireless mesh networks include health systems, security, building automation, transportation, and broadband home networking.

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
