Pricing Model

We introduce a pricing model as a fair-enough price-determining mechanism to motivate providers and users to participate. We adopt the same pricing model as Zhai et. al. (2018) which considers a fixed allocation matrix. Then, the winning resources of each user will be as follows:

resource𝑖 =∑𝐴𝑖,𝑗 ×∑𝑠𝑗,1≤𝑖≤𝑚,1≤𝑗≤𝑛

The following two equations are the per unit price for tasks and providers accordingly.

price (task per unit)𝑖 = 𝑣𝑖 , 1 ≤ 𝑖 ≤ 𝑚, 1 ≤ 𝑗 ≤ 𝑛 ∑𝑥𝑖,𝑗*∑𝑠𝑗

price(provider per unit)𝑗 = 𝑐𝑗 ,1 ≤ 𝑗 ≤ 𝑛 ∑𝑠𝑗
