摘要：A few numbers of packets are locked in the network for random time periods may occur due to the mobility of nodes in Mobile Ad hoc networks, �This problem may leads to packet drop, as it stays longer time period in the loop than the allowable Time to Live (TTL) value�. The objective of the paper is to provide Loop-Free Multipath routing to reduce the packet drop and hence the network performance will be enhanced. In this paper, our proposed work of �Loop-free Multipath Probabilistic Scheme based AODV (LMPSAODV)� is simulated using network simulator NS-2.34 to evaluate network performance and the results are presented on various scenarios in terms of packet delivery ratio (PDR), total dropped packets, routing overhead, end-to-end delay and retransmission rate. The performance will be measured with two different TCP variants namely TCP Tahoe and SACK. Each TCP variant uses different ways of congestion control algorithm. The simulation result shows that �the performance of LMPSAODV with TCP SACK performs better to the changing network sizes�.
