In Mobile Ad-hoc NETwork (MANET), mobile nodes act as routers themselves, keeping route information to reach other mobile nodes, and helps to forward data packets from one mobile to another. The performance of the different mobility models such as Random Walk (RW), Random Way-Point (RWP), Manhattan Mobility (MM), Reference Point Group Mobility (RPGM) are analyzed in TCP (Transmission Control Protocol) environment using NS2 software under Linux platform. Depending on the type of TCP implementation the behavior was different, due to the activation/missing of the following congestion control algorithms: \"Slow-start\", \"Congestion avoidance\", \"Fast recovery\" and \"Fast retransmit\".
