Wireless mesh network

In a WMN, each router forwards packets on behalf of other nodes (thatwhich may not be within direct wireless transmission range of their destinations). Moreover, the gateway functionalities enable the integration of WMNs with various existing wireless networks, such as Wi-Fi, cellular networks, WiMax, and others. In this type of network, the nodes automatically establish and maintain mesh connectivity among themselves (forming an ad hoc network). As a result, a WMN is self-organized, self-configured, and redundant (the failure of one node does not prevent other nodes from communicating).

WMNs have the potential to improve the performance and capacities of other types of ad hoc networks, including wireless local area networks (WLANs), wireless personal area networks (WPANs), and wireless metropolitan area networks (WMANs). WMNs are an universal solution applicable to a variety of small, medium, and large-scale scenarios, including personal, local, campus, and metropolitan areas. Mesh technology finds many applications in wireless multi-player gaming, campus connectivity, military communication, municipal networks, and more. Some of the specifications of WMNs include:

Client meshes are mobile ad hoc networks, where each client acts as an independent router with no centralized routing control. In this type of infrastructure, clients can perform network tasks such as routing and forwarding.

Hybrid meshes are the most generic type of architecture, combining both infrastructure and client meshes. Infrastructure provides connectivity to other networks such as Internetinternet, and clients provide a dynamic extension of the network.

To lessen the interference and increase the capacity of a wireless mesh network, the devices may also transmit over different non-overlapping channels provisioned in the IEEE 802.11 standards. This is done by equipping the routers with multiple radio interfaces tuned to isolated individual channels. The network capacity of a multiradiomulti-radio wireless mesh network is dependent on how various channels are assigned to each radio interface to form a minimum-interference mesh network. For the mesh network to remain connected, the number of channels assigned to a router has to be at most the number of interfaces on the router.

Extended bandwidth and redundancy are the primary benefits of wireless mesh network architecture. By rerouting traffic through multiple paths, wireless mesh networks can cope with link failures, interference, power failures or network device failures. Each device in a wireless mesh network is typically called a mesh node and is connected with multiple other mesh nodes. Wireless mesh networks are also called multi hopmulti-hop networks because each mesh node can reach another node by going through multiple hops and leveraging other nodes as repeaters.

Wireless mesh radios can communicate only with other mesh radios using similar protocols, such as SSID, end-to-end encryption, wireless encryption, etc. Mesh nodes do not function as wireless access points (APs) and communicate exclusively with other wireless mesh nodes, in a particular SSID and mesh ID network, which provides added security at the physical layer.

• The disaster management &and rescue operation segment: withsegment—with the increasing proportion of climatic disasters due to rise in temperatures, there is incentive for rescue operations to be improved with the aid of mesh networks.

The 2.4 GHz radio frequency band segment made up the largest portion of the WMN market in 2018. Various industrial, medical, and scientific instruments mostly operate in the radio frequency bands, which is expected to boost the segment growth. Moreover, this radio frequency band covers longlong- and small rangesmall-range antennae that are used to keep the system compact. This segment is also expected to dominate the North American market as this region has the largest number of innovations in communications infrastructure.

The reduced latency provided by 5G networks will be beneficial for autonomous vehicles, as they will be able to respond 10-100 times faster than over ordinary cellular networks. A vehicle-to-everything (V2X) communication network is a possibility in the future. This would enable vehicles to automatically and instantaneously respond to objects and changes around them. It is necessary for autonomous vehicles to be able to send and receive signals in milliseconds in order to brake or shift directions in response to road signs, hazards, and people crossing the street.

The low latency of 5G will enhance the immersiveness and interactivity of AR and VR applications. In industrial applications, for instance, a technician equipped with 5G-powered AR goggles could have their vision augmented with an overlay whichthat would aid them by identifying parts of machinery, providing repair instructions, or highlighting hazards.

• Mesh routers and links used to support communication in the backbone of the network are relatively static.

• Mesh routers are typically connected to the electrical grid and therefore are not power constrained; mesh routing protocols do not have energy consumption restrictions.

• The traffic model may concentrate in certain paths, predominantly between mesh routers and gateways; the majority of links are used in the zones near the gateways.

• WMNs have high user and traffic volume capacity, making them suitable for establishing broadband connections for Internet access in populated communities.

• Transmission errors: the unreliability of the wireless medium may lead to transmission errors.
• Link and node failures: nodes and links may fail due to unfavorable environmental conditions.
• Incorrect routes: due to node/link failures or alterations in the network, routes may become obsolete or refer to an incorrect system state.
• Congested nodes or links: due to the topology of the network and the nature of the routing protocols, congestion among certain nodes or links may occur and cause higher delay or packet loss.

• Fault tolerance: introducing redundancy in the network or providing backup routes to be used in case of a failure increases fault tolerance at the routing level.

• Throughput enhancement: in a mesh network, some links can have limited bandwidth. Routing along a single path may not provide enough bandwidth for a connection. The establishment of multiple paths to route data could potentially satisfy greater bandwidth requirements.

• Load balancing: since traffic distribution is not uniform throughout the network, spreading traffic along multiple routes can alleviate congestion and bottlenecking.

• Security: single-path routing protocols are more vulnerable to routing attacks; multipath solutions offer superior attack resilience.
