In this Letter, a combined algorithm known as receiver‐assisted slow start (RASS) and feedback‐assisted recovery (FAR) proposed to address the joint optimisation problems of transmission control protocol (TCP) such as non‐optimal initial window (IW) size, slower window growth and spurious window deflation under multi‐hop wireless (MHW) networks. The RASS fix the sender's optimum IW size from the receiver's advertised value and replaces the conventional exponential window growth with enhanced window increment mechanism that significantly accelerates the transmission rate. The FAR uses relay router's feedback information to regulate false transmission rate reduction during packet drops. The simulation result reveals that the proposed algorithms had a substantial improvement in throughput and reduction in packet latency over the existing standard New Jersey and non‐congestion events algorithms under MHW environment.
