Abstract: This paper proposed an IADTCP (improvement ad hoc network tcp congestion control) algorithm, which improved TCP congestion control algorithm for mobile Ad Hoc networks through employing end-to-end identification. The IADTCP improved the slow-start strategy in traditional Ad Hoc network to resolve the problem that the congestion window grows un-smoothly, used two metrics IDD(inter delay difference) and STT (short term throughput) to perform multi-metric joint identification for congestion detection, used PLR (packet loss ratio) and POR (packet out of-order delivery ratio) to identify the network states of CHANNEL ERR and ROUTE CHANGE. Then the sender side would take advisable measures in light of network state information carried by back ACK package. The simulation resups have validated the feasibility and efficiency of the proposal.
