hi,
I'm trying to draw up a plan for a wireless sensor network that is going to be integrated into a system which monitors the activites of elderly people to see if they need some sort of assistance. I wanted to know if any one had any experience of building a WSN and if so what parts i should be looking to use?
I've built a wireless link before, but it was an omnidirection link, with one transmitter and one reciever. I think for the WSN i'm going to need a set of transcievers with one transciever acting as a central node that dictates when the other nodes with the sensors attached can transmitt data. Has anyone done anything like this before does this sound right?
