Abstract:

This paper proposes an environment-aware bestretransmission count selected optimization control scheme over IEEE 802.11 multi-hop wireless networks. The proposed scheme predicts the wireless resources by using statistical channel state and provides maximum retransmission count optimization based on wireless channel environment state to improve the packet delivery success ratio. The media access control (MAC) layer selects the best-retransmission count by perceiving the types of packet loss in wireless link and using the wireless channel characteristics and environment information, and adjusts the packet forwarding adaptively aiming at improving the packet retransmission probability. Simulation results show that the best-retransmission count selected scheme achieves a higher packet successful delivery percentage and a lower packet collision probability than the corresponding traditional MAC transmission control protocols.
