In today＊s most of the Adhoc networks needs the reliable connection to transfer the data. Most number of data packets loss is experienced in the Adhoc networks due to Transfer control protocol(TCP)＊s high channel error rate and link failure. To improve TCP performance in Adhoc networks a number of schemes have been proposed, where Adhoc networks use the multi-hop wireless connectivity, where the network has quickly changing network topology. ELFN (Explicit Link Failure Notification) is one mechanism to manage link failures with dynamic cache update scheme to improve the TCP performance considerably. In this paper, we propose a mechanism which significantly increases the throughput of TCP＊s performance with ELFN based Dynamic cache update scheme using Dynamic source routing protocol. Our simulation results using ns-2 simulator, mentions that our scheme can handle link failures in effective way, and improves TCP＊s performance considerably.
