If network congestion occurs, packets cannot be delivered timely, the data rate decreases significantly and the required level of QoS cannot be achieved for all nodes. Especially in Home Area Networks (HANs) with limited uplink bandwidth for internet access, congestion is a major problem. Different approaches for congestion aware link sharing and QoS provisioning exist. Also the Distributed Fair Congestion Avoidance Protocol has been proposed for this purpose, but has to be modified to work efficient in HANs. In this paper, we present an enhanced version of the former proposed DiFCAP protocol which works proactive and independent of the congestion handling capabilities of Transport Layer protocols.
