In mobile ad hoc networks (MANETs), congestion can occur due to limitation in resources and lead to high packet loss, long delay and waste of resource utilization time. The major objective of congestion control is to best utilize the available network resources by keeping the load below the capacity. The great demand for capacity, place particular emphasis on congestion management approaches. Recently, researchers have developed many effective and well studied algorithms for congestion control within Transmission Control Protocol (TCP) to improve its performance over MANET environment. TCP is designed to be reliable and ensure end to end delivery in wired network. However, each existing TCP variant over MANET has its weaknesses and strengths when changing MANET factors like: node mobility, traffic loads, network size and wireless channel conditions. In this paper a new approach to decrease packet loss using dynamic path congestion estimation. The simulation results show an improvement in TCP performance over MANET in different scenarios.
