Q4. Formulate the amount of energy saved (E) during offloading for the given data.
Energy cost/second while when mobile phone is doing computation = C1
Energy cost/second while when mobile phone is idle = C2
Energy cost/second while when mobile phone is transmitting the data = C3
Speed of cloud to compute k instructions = Sc
Speed of mobile to compute k instructions = Sm Data need to transmit = D
Bandwidth of the wireless Internet = B
A) E = C2(k/Sm) – C1(k/Sc) – C3(D/B)
B) E = C1(k/Sm) – C2(k/Sc) – C3(D/B)
C) E = C3(k/Sm) – C2(k/Sc) – C1(D/B)
D) E = C1(k/Sc) – C2(k/Sm) – C3(D/B)

Answer: B) E = C1(k/Sm) – C2(k/Sc) – C3(D/B)
