An Approach Using Dynamic Deferred Acknowledgement to Improve TCP Performance in Multi-Hop Wireless Networks
The network communication protocol designed for sending data packets over the Internet is the Transmission Control Protocol. This paper proposes an approach to improve the performance of TCP in Multi-Hop Wireless Networks. The approach aims to minimize the number of acknowledgements using Delayed Acknowledgement mechanism. The performance of TCP is reduced due to the generation of acknowledgement for each of the incoming data packet. The TCP performance wanes chiefly when the ACK and data packets encounter and impact one another as they traverse the same path. The performances of TCP in Multi-Hop Wireless Networks are affected due to contention and collision. Transmission Control Protocol performance can be improved by decreasing the number of acknowledgements using Delayed Acknowledgement mechanism. A receiver with an adaptive Delayed Acknowledgement mechanism is proposed to improve the performance of TCP in Multi-Hop Wireless Networks. A Delayed Acknowledgement (DAK) Algorithm is proposed to improve the Transmission Control Protocol throughput compared to the regular Transmission Control Protocol. The proposed approach is simulated in Network Simulator-2 (NS-2). The simulation results illustrate the efficiency of our approach in terms of packet loss.
