Size Based Throughput Optimization of Dly-Ack Over the IEEE 802.15.3 Networks
In this paper, the authors study on the one hand under Delayed-ACKnowledgement (Dly-ACK) mechanisms the option of using ACK Request to improve system robustness, and on the other hand the incorporation of effective retransmission schemes such as Hybrid Automatic Repeat reQuest (HARQ) to improve system throughput for an IEEE 802.15.3 compliant system. An expression of throughput is derived in terms of system parameters and channel conditions. A constrained optimization problem for system throughput is formulated. It is then solved numerically due to the high degree of nonlinearity in the payload size.
