If the Lightning Network is so useful today, it is in great part thanks to the fact that payments can be routed inside the network: if Alice wants to pay Bob, it isn’t necessary that she has a direct channel with him. Instead, she can have a channel with Carol and, if Carol has a channel with Bob, use Carol’s channel to reach Bob.

Intro Mesh networks are networks were nodes connect to one another dynamically and without any hierarchy. There is no central authority, every node is connected to other nodes with which it exchanges data. Bitcoin already looks a lot like a mesh network at the protocol level. Consider transactions or blocks propagation for example....
