If I have four Raspberry Pi acting as different sensors and I want to communicate their sensor data to a central computing device located in the same physical space, what type of network communication should I use?
Based on my limited understanding of network communication and a little bit of research, it seems like I can establish some type of ad-hoc wireless network without an access point. An example would be a mesh network where every device has communication to each other. But isn't this redundant if I just want to send my sensor data to a central node? I also want to avoid any physical wiring hence I'm looking for a wireless network setup that has low energy consumption and fast performance as I intend to do real-time image and object recognition on the central computer.
