Abstract :
More attention has been paid to congestion control in the emerging area of wireless sensor network (WSN). However, most research works in the past stayed at the level of algorithm design or modification, and seldom sought solutions on the viewpoint of architecture. In this paper, Active Networking (AN) technology is used to make congestion control more responsive to detect/recover congestion in WSN. We design a simple Active Backpressure (BP) mechanism to allocate bandwidth Proportional to the Size of tree (ABPS). ABPS introduces programs in each data packet that tell nodes how to react to congestion, and quickly converges to a fair and efficient rate. Finally, we evaluate ABPS extensively on a 50-node wireless sensor network. Simulation results validate the effectiveness of our ABPS.
