Abstract

Mobile Ad Hoc networks are collections of mobile nodes, dynamically forming a temporary network without pre-existing network infrastructure or centralized administration. Transmission control protocol (TCP) provides connection oriented, reliable and end to end mechanism. Comparing to wire networks, there are many different characteristics in wireless environments. In this paper an improved mechanism for TCP congestion control is presented. It considers the influences sending rate to TCP sender’s packet only by the congestion. The drop rate for TCPM is calculated according to total packet received and total packet acknowledgment in network. So, there is less packet drop in transmission. The comparative study of Modified TCP (TCPM) with other TCP variants is also carried out on various parameters like pause time, size of network. The improved mechanism was implemented with fewer overheads and effectively improves reliability with small variances of throughput and delay. Implementations and Simulations were performed in QualNet 5.0 simulator.
