Explanation / Answer
1) Wireless mesh network:
A wireless mesh network (WMN) is a mesh network created through the connection of wireless access points installed at each network user's locale. Each network user is also a provider, forwarding data to the next node.
The networking infrastructure is decentralized and simplified because each node need only transmit as far as the next node.
Wireless mesh networking could allow people living in remote areas and small businesses operating in rural neighborhoods to connect their networks together for affordable Internet connections.
