Abstract

Network Congestion is a highly undesirable situation for every type of network. Especially in low powered Wireless Sensor Networks (WSNs), congestion can be proven critical for the network's proper operation. In case of congestion in a WSN, the network is programmed to react, either by reducing the data rate of the sources or by creating multiple routing paths to the sink, thus avoiding the network's congested point. In this paper we perform a comparison of these two techniques, comparing one algorithm of each category. Results depict the advantages and disadvantages of each category.
