NettetIn the star topology shown in Figure (2.5), the communication is established between devices and a single central controller, called the PAN coordinator [45]. Nettet30. sep. 2024 · The disadvantages of star topology are: Higher cost – Usage of switch/router in the topology incurs high cost. Increased maintenance – Installation of hub needs frequent maintenance as this is the central part of the system. Immobile – Even there are wireless topology connections, mostly wired connections are used.
NettetThe extended star topology is mostly used where there is a need for connecting multiple nodes to one central node and control all nodes from the central node. Some of the uses are as mentioned below: It can be … NettetSENSOR NETWORK TOPOLOGIES 3.1 Star Topology In Star Topology, ...
