Abstract
We consider the communication from a cooperative sensor network to a mobile access point. We assume that sensors are informed with a global message and some nodes are misinformed with random messages. Nodes transmit to the mobile access point in a pre-scheduled order. We derive an achievable rate for the information retrieval process when sensors are transmitting at a time. For the Gaussian multiple access channel under the total network power constraint, we show that the maximum achievable rate for the Gaussian multiple access channel is O(log 2 d), obeying the same scaling law as the capacity of an Gaussian multiple-input-single-output channel.
