I would like to use a wifi protocol for image transmission. I am planning to use 802.11p or ac. I would like to know the important differences between these two so that I can finalize a suitable one for my outdoor application. Thanks in advance.
I think 802.11 ac will be suitable for your application as it has higher throughput. 802.11 p is designed specially for VANET. For more information read following links.

802.11p is for ITS intelligent Transport servies or VANETS. This is for both PHY and MAC layer.
This is another reference:

with 802.11ac the maximum number of MIMO streams is increased to eight. So with no other improvements (even though there ARE many more), 802.11ac would double the overall available throughput.
speed 1Gbps. As consequence, the frequency is higher (from 2,4 to 5GHz). Away from a crowdy frequency (shared with wireless phone and other services)
They have quite different scopes. 802.11p has a specific target in the vehicular scenario; it is intended for higher reliability and limited throughput (from 3 to 27 Mbps raw data rate) in short range vehicle-to-vehicle and vehicle-to-roadside communications, to be used in dedicated frequencies mainly for safety purposes. 802.11ac is instead designed for high throughput, through the use of large bandwidth and many antennas.
