The characteristics of Mobile Ad hoc Network (MANET) like error and reordering degrades the performance of TCP-based applications. Among the many proposals to reduce the impact of non-congestion events, TCP-NCE has been designed as the unified solution to discriminate between non-congestion and congestion events, and to respond to the events. Our initial analysis on TCP-NCE and other schemes (TCP-DCR and SACK-TCP) showed that the existing schemes including TCP-NCE fail to improve end-to-end performance in the presence of congestion, error, and reordering due to mobility and multipath routing. To overcome this problem, we designed ``Enhanced TCP NCE'' protocol to reduce the false differentiation on non-congestion events and to optimize the response procedure to those events. Our simulation results showed that the enhancement increased the performance by 15–20{%} over TCP-NCE. In addition, the consistency in yielding the higher performance throughout the simulation is observed for our protocol
