3.1 Star Network

Star topology is the easiest topology in the three kinds of network structures. It consists of one central node and several peripheral nodes. Each peripheral node can only communicate with the central node and cannot communicate directly with the other peripheral nodes. Peripheral nodes can communicate indirectly through forwarding by the central node.

The star topology has the advantage of simplicity and directness, thus it has the lowest latency of the networks presented here. However, this network coverage is the smallest because of the limited number of peripheral nodes that can be connected with the central node.
