The network topology is the way that the devices are connected and communicate with each other and with the gateway or the cloud. The network topology affects the power consumption of the devices, as it determines the distance, the interference, the routing, and the redundancy of the communication. You should manage the network topology of your IOT devices by choosing the best layout, the optimal number of nodes, the appropriate routing algorithm, and the suitable redundancy level. You can do this by using techniques such as mesh networking, clustering, multi-hop routing, and load balancing. For example, mesh networking allows the devices to form a self-organizing and self-healing network, where they can relay data to each other and to the gateway, reducing the power consumption and improving the coverage. Clustering divides the network into groups of devices, where one device acts as a cluster head and communicates with the gateway, reducing the power consumption and the interference. Multi-hop routing finds the shortest and least congested path for the data, reducing the power consumption and the latency. Load balancing distributes the traffic and the workload among the devices, reducing the power consumption and the congestion.
