Cooperative Sensor Networks with Misinformed Sensors

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. The mobile access point employs a polling-based multiple access control to collect information from the sensor network. We derive the maximum achievable rate for the information retrieval process when d sensors are activated at a time. For the Gaussian multiple access channel under the total network power constraint, we derive an achievable rate expression and 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-singleoutput channel.
