Gain from mobility The gain from mobility, G, can be characterized as the ratio of Pmiss (static sensor node) to that of Pmiss (mobile sensor node). Using the same set-up as Problem 12.6, let a¼100, l 2 (5, 20) and the distance of the obstacle x 2 (20, 35). Plot the curves of gain versus obstacle distance for l in steps of 5. What conclusions may be drawn?
