Performance Assessment of Congestion Control Transport Protocols for Wireless Sensor Networks

In wireless sensor networks (WSNs), congestion may bring about degradation of overall channel quality and increased loss rates, leads to buffer drops and enlarged delays, and tends to be disgustingly unfair toward nodes whose data has to traverse a larger number of hops. Provisioning a WSN so that congestion is an infrequent occasion is quite challenging task. This paper presents a performance comparison study focusing the most relevant congestion control transport protocols for wireless sensor networks. The main objective is to study some characteristics of these types of protocols, focus in energy saving and penalty fidelity with the help of simulations.
