TLP ALGORITHM USED EFFECTIVELY IMPROVES TCP PERFORMANCE IN DATA TRANSMISSION AND RECOVERY FOR CLUSTER BASED IN WSN’S

TLP's goal is to reduce tail latency of short transactions. It achieves this by converting retransmission timeouts (RTOs) occurring due to tail losses (losses at end of transactions) into fast recovery. TLP transmits one packet in two round-trips when a connection is in Open state and isn't receiving any ACKs. The transmitted packet, aka loss probe, can be either new or a retransmission. When there is tail loss, the ACK from a loss probe triggers FACK/early-retransmit based fast recovery, thus avoiding a costly RTO. In the absence of loss, there is no change in the connection state. Basic of this paper Identity based digital Signature and Identity based online of line algorithm for the cluster based wireless sensor networks is used. Identity based digital signature computes the digital signature signing process. Identity based online of line algorithm reduces the complexity of computational overhead in cluster head. This project effectively avoids long timeouts and thereby improves TCP performance. The method for efficient data transmission using Identity based digital signature is also implemented for minimizing end-to-end delay using network simulator
