Wireless Sensors refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. Wireless Sensors typically measure environmental conditions like temperature, sound, vibration, pollution levels, humidity, wind, etc.Thuê IoT Engineers
The main research is about how to optimize LoraWAN performance (maximize throughput, minimize latency/delay, minimize sensor power consumption, and maximize network coverage).You can use MatLab, NS2, NS3, OMnet++, Cooja and so on. There is no limit which simulater you can use. I just need the result as I mentioned above.
