Heterogeneous mesh network (ad hoc)
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.
Heterogeneous mesh network (ad hoc)
- 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
