Abstract
Congestion is a significant problem that faces streaming media applications in Wireless Sensor Networks (WSN). This problem occurs when the sensor receives traffic that exceeds its maximum forwarding rate causing more packet loss, more delayed data and overall network quality degradation. The Datagram Congestion Control Protocol (DCCP) is a congestion control protocol that works on the transport layer and is suitable for use by multimedia applications. DCCP supports many congestion control mechanisms that the application can choose among them according to the type of the application. We propose an algorithm to enhance the performance of DCCP protocol using TCP-like mechanism by modifying the sending rate through tuning some critical parameters which are, slow start threshold (ssthresh), congestion window (cwnd), maximum retransmission timeout (max rtx to) and initial retransmission timeout (initial rtx to) with respect to the reset function, as this function is invoked to recover from congestion or any error happening in the network.
