Abstract: This paper presents the new throughput analysis of the adaptive three modes for Packet Combining (PC), Modified Packet Combining (MPC) and Aggressive Packet Combining (APC) techniques. The three modes in this paper consist of X (low probability of packet error), Y (moderate probability of packet error) and Z (high probability of packet error) channel states. The three states are based on the number of received acknowledgement (either positive acknowledgement (ACK) or negative acknowledgement (NACK)) by Transmitter (Tx). The PC, the hybrid PC+MPC and the hybrid MPC+APC techniques are implemented in X, Y and Z channel states respectively for enhancing the fast error correction and also to reduce retransmission of duplicate copies. Thus, the proposed protocol is simulated using MATLAB and the results yield better performance over conventional PC, MPC and APC techniques in terms of throughput, the probability of packet error correction and energy consumption.
