Abstract

With the advancement in technology, today most of the end-host devices are equipped with multiple wired/ wireless interfaces and capable of using them in parallel. This has led to research in taking advantage of utilizing additional available network resources simultaneously such as multiple paths between the multi-homed end devices to achieve better performance. In Mobile Ad hoc Network communication concept among the mobile nodes or users allows to communicate with each other in a multi hop fashion without any fixed infrastructure and centralized administration. Due to dynamic forming topology the efficient and reliable routing is the main issue in MANET. The multipath protocol like AOMDV is provide the multiple path for data transmission and receiving by that the reliability of data successful receiving is enhanced and possibility of congestion is reduces. The TCP protocol is the reliable protocol for communication because of the mechanism of Acknowledgement (ACK) that reduces the possibility of congestion. In this research we proposed a new Local Route Repare (LRR) approach to enhance TCP variant performance of BIC, Vegas and combination of BIC and Vegas (Hybrid) approach with AOMDV routing protocol and reduces the congestion in network. The each TCP Variant protocol has different strategy of communication and the TCP hybrid provides the better performce also as compare to BIC and Vegas. The LRR mechanism is applied on BIC, Vegas and Hybrid with AOMDV protocol that provides the mich better performance as compare to normal TCP Variant performance. The proposed approach provides the assistance on the network inside information such as failure of a link, more accurate available bandwidth and packer drop analysis. By utilizing this information, TCP at the terminal nodes will be able to adjust its data rate closer to the network capacity and to improve the performance of both TCP variants and network accordingly.
