Counting the Number of re-transmission for a single UDP packet transmission in IEEE 802.11

I was working with a client-server project based on UDP and 802.11 as a link and physical layer. There, Client was trying to probe some packets in the wireless channel to gauge channel condition. This function is required to set up the transmission speed & estimate packet drop rate in my client application. To carry out that function, It is required to measure the number of re-transmission that is occurring in IEEE 802.11. In the transport layer, there won't be any re-transmission as UDP is used but if the wireless channel is bad (no acknowledgement from the receiver MAC) the IEEE802.11 wifi NIC will re-transmit. How should I measure the number of re-transmission in IEEE 802.11 layer? Say for 200 packets from application how many re-transmission in IEEE 802.11 layer?
Or Is there any kernel hack that will stop the IEEE802.11 re-transmission feature?

I think you need to clarify the difference between the network layers. Packets are at the network level, where addressing happens (i. e. TCP/IP addresses for TCP and UDP packets); 802.11 doesn't come into play here. That's a specification for the physical and data link layers. The wireless network infrastructure retransmitting is not the same as a host retransmitting a network packet (which doesn't happen over UDP anyhow; that's one of the main differences between UDP and TCP).

I think you need to clarify the difference between the network layers. Packets are at the network level, where addressing happens (i. e. TCP/IP addresses for TCP and UDP packets); 802.11 doesn't come into play here. That's a specification for the physical and data link layers. The wireless network infrastructure retransmitting is not the same as a host retransmitting a network packet (which doesn't happen over UDP anyhow; that's one of the main differences between UDP and TCP).
