Wireless Mesh Network (WMN) - a communications network made up of radio nodes organized in a mesh topology. Clients can be laptops, cell phones, and other devices. Mesh routers forward traffic to/from gateways that may or may not connect to the Internet. This is a good way to communicate with others when the Internet goes down or in any communications emergency situation.

It’s Time to Take Mesh Networks Seriously (And Not Just for the Reasons You Think)
Mesh networking - To ensure all its paths' availability, the network must allow for continuous connections and must reconfigure itself around broken paths, using self-healing algorithms such as Shortest Path Bridging. Self-healing allows a routing-based network to operate when a node breaks down or when a connection becomes unreliable.
