Wireless Sensor and Low-Power Networks

Start with sensor networks

The Sensor networks mind maps offer a starting point for this page. They describe wireless sensor networks in terms of low power, small size and low cost. They also connect sensors to measurements such as pressure, temperature and humidity. Start with one of these maps and follow its branches from the network’s features to what the sensors monitor.

Afterward, look at the IEEE 802.15.4 Standard for Low-Rate Wireless Networks mind map. It introduces a standard intended for applications with low power consumption and relaxed data-rate requirements. Compare those points with the features in the sensor network map.

Explore design and optimization

The WSN Optimization mind maps connect coverage and connectivity with factors such as time, energy and the number of nodes. They also include node deployment and reallocation. Use the branches to organize these ideas before returning to the maps for a closer look at how they relate.

The LoRa mind map covers chirp spread spectrum, bandwidth and interference, as well as a comparison between LoRa and WiFi. It offers another way to explore the low-power networking material on this page.

Use a quiz alongside the maps

The IoT Sensors & MATLAB quiz includes questions about Bluetooth uses and unauthorized access through a Bluetooth connection. Try it after looking through the maps, then return to the listed resources to organize the points you want to study further. The quiz and maps address different details, so use each for the material it covers.

Place the topic in the unit

Wireless Sensor and Low-Power Networks is a section of the Wireless Networking unit in Networks and telecommunications. The resources here give university students material to study and teachers material to use when covering this section. Pick a map that matches the idea you want to explore next.
