ABSTRACT: The performance of the congestion control algorithms of most of the reliable transport protocol of internet, particularly wireless sensor networks (WSN) and mobile ad-hoc networks, are not satisfactory under a high density sensor network applications, since those algorithms were designed mainly for wired networks and not for WSN. Authors in their previous work ,  and , have evaluated the performance some of the well-defined transport protocols on a congested sensor network scenario and established that the DCCP transport protocol is more suitable for sensor network applications. An improved reset frequency controlled parameter re-estimation method for enhanced Congestion Control in DCCP_TCPlike protocol, RC_DCCP_TCPLike, is suggested in this paper. The proposed protocol was implemented on a typical network scenario, simulated using ns2, and its performance was evaluated with respect to standard metrics viz.throughput, dropped packets, energy consumption, routing load, MAC load and end-to-end delay and compared with those of the networks with normal DCCP_TCPLike protocol. From the results it is observed that the performance of RC_DCCP_TCPLike protocol based networks is better than normal DCCP-TCPLike based networks.
