Model Name: OPNET M-TCP model Opnet Modeler version: 11.0 PL1 Release date 2004-12-08 Opnet Model Library: 11.0 Release date 2004-12-01 The OPNET model implements M-TCP, a TCP variant proposed by K. Brown and S. Singh. M-TCP was designed to perform well in the presence of frequent and lengthy disconnections in mobile cellular networks. Such networks are characterized by low bit-rate wireless links subject to dynamically changing bandwidth. The model is employed to evaluate and compare the performance of TCP Reno and M-TCP with and without disconnections. The OPNET M-TCP model contains a network architecture consisting of a fixed host (FH), a supervisor host (SH), and mobile host (MH). The FH is connected to the SH via a full duplex wired 10Mb/s Ethernet link while the MH is connected to the SH through an IEEE 802.11 11Mb/s wireless link. The OPNET M-TCP model includes an M-TCP process as a transport protocol in the SH, which is modeled using the OPNET WLAN Ethernet advanced router. It handles the routing and transport protocol adaptation for the mobile users. Revised model (version 11.0.PL1) created by Modupe Omueti. Original model (version 8.0.C) created by Wan Gang Zeng, Meihua Judy Zhan, and Zhiwen Lin.
