In Section 5.3, we provided an outline of the derivation of the efficiency of slotted ALOHA. In this problem we'll complete the derivation.
a. Recall that when there are N active nodes, the efficiency of slotted ALOHA is Np(1-P)^N-1. Find the value of p that maximizes this expression.
b. Using the value of p found in(a), find the efficiency of slotted ALOHA by letting N approach infinity. Hint:(1-1/N)^N approaches 1/e as N approaches infinity.
