Alice is a farmer who lives in a remote ranch in Texas. She has chosen to improve the way she monitors her corn field. She wants to install wireless sensors to monitor her crops, and collect environmental data. She has a good understanding of electronics, and has decided to design her own sensors and communication infrastructure based on off-the-shelf products.

Problem 3) (10 points) Alice wants to wirelessly connect the sensors to her phone and view the status of her crops and field on a phone app. Additionally, she wants to wirelessly connect some actuators, such as sprinklers, to the app on her phone so that she can turn them on and off. She thinks that if the sensors used WiFi (802.11) in the ad-hoc mode, it will be the best solution for her. Is she right in thinking so? Are there any potential issues she is overlooking? Can you suggest a better suited protocol? Explain your answer.
