Narrative:
I was circumnavigating the las vegas class B airspace after departing ZZZ and flew to the west side of the class B at 3900 feet. The floor in this area is 4000 feet. My destination was hnd. I contacted the hnd tower and was given instructions to enter a midfield downwind for 17 right. Tower called out a 737 at my 12 o'clock and 500 feet above that was landing at las runway 1. I had that airplane in sight. I was concerned that I would encounter wake turbulence from the jet as I crossed his flight path at only 500 to 600 feet below. I adjusted my crossing angle by approximately 10 degrees to the left to lessen the chance of an aircraft upset. I may have inadvertently brushed the edge of the inner ring of the class B airspace as I was flying parallel to it. My eyes were on the jet not the moving map. There were no other airplanes in close proximity to my position at that time. The terrain around the las vegas class B is mountainous with little vertical room to maneuver. My actions were based on my [many] years of experience and my desire to fly in a safe and proficient manor. I did encounter the wake turbulence; but it was an up and down series of jolts and not a dreaded wing roll; because of my actions. I believe that the best way to prevent the chance of an encroachment would be to fly a greater distance from the class B inner ring.
