Mesh architecture is a multipoint-to-multipoint architecture with one or more Internet interconnection points. In a mesh network, each network node can connect to any other network node that is turned on and within wireless range. Mesh networks are usually deployed in areas where many end users are located relatively close to each other, such as from one block up to one mile apart.
Each mesh network node performs two functions:
As a wireless router/repeater
As an end node
Packets can travel through several intermediate wireless nodes to reach the desired end user node. If one or more of the intermediate nodes is down, the packet is dynamically rerouted through other intermediate nodes. Figure 3-5 shows a diagram of a mesh architecture ...
