Wireless mesh networks (WMNs) will dominate in the coming decade as they are one of the primary technologies. They will assist in understanding the awaited dream of network connectivity anywhere, at any time, at a low cost. As a result, in the next-generation Internet, they will play a significant part. Their ability to self-organize greatly minimizes the complexity of network implementation and maintenance, necessitating a low initial investment. Simple mesh clients and mesh routers make up these networks, which make the backbone of WMNs. Mesh routers have limited mobility. They connect mesh and traditional clients to the network. The bridge functionalities and the gateway in mesh routers can be used to connect WMNs to other networks like the cellular, Internet, IEEE 802.16, IEEE 802.15, IEEE 802.11, sensor networks, etc. Mesh clients can be mobile or motionless, and they can establish a client mesh network with mesh routers and other mesh clients. Wireless personal area networks (WPANs), wireless metropolitan area networks (MAN), Ad hoc networks, and wireless local area networks (WLANs) are expected to benefit from WMNs, which are expected to overcome restrictions and considerably increase performance. These networks provide wireless services to various applications in metropolitan locations, local, campus, and personal.
