Normal Network State

This simulation shows a 100 node network operating under the control of the sas protocol in its normal steady state. Note that there is very little activity—1 receive attempt by each node and only a few random transmission attempts. The sensor network spends almost all of its time in this state, so reducing energy consumption in this state is of prime importance.

In this short snippet of data (a single 1 second frame), transmissions are shown as red circles about the node location, completed receptions are shown as blue circles with a vector back to the transmitting node, receive opportunities that did not result in a reception are shown as green circles, and collisions are shown as yellow circles.
