A project team has been contracted by a company to develop a bushfire detection system to sense, locate and track bushfire smoke and monitor weather conditions such as temperature and wind direction. As part of the project, a prototype is developed. A network of sensor nodes placed 100 m apart is located in the bushland. The nodes communicate with each other while sampling the air to detect bushfire smoke in the immediate area. The central command centre monitors each sensor node to locate the source of a bushfire, sending instructions to emergency services. (a) Describe the benefits of creating a prototype for this system. (b) Explain why live data should be used to test the bushfire detection and monitoring system. (c) Suggest and justify suitable transmission media for each of the following: between sensor nodes from the central command centre to the sensor nodes within the central command centre.
