"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."
