Due to the frequently changing topology and high mobility of nodes in multihop wireless network, there may be chances of congestion which results in loss of TCP sequence and degrades the network performance. In existing congestion control works, hop by hop detection incurs huge overhead. Moreover, the waiting time of the source node in obtaining the acknowledgement from the receiver, will be high when the number of hops in creases. To overcome these issues, this paper proposes a Proxy based intelligent acknowledgment technique for multihop wireless network. In this technique, proxy nodes are selected along the transmission path, which determine any missing TCP sequence. In this way, packet loss is monitored and retransmission is requested from the source node, thus, ensuring proficient data transmission in the network. Simulation results show that the proposed technique reduces the delay and improves the throughput.
