By leveraging convex optimization theory and the Gibbs sampling method, the statistical approach is illustrated. A statistical computation model and a statistical transmission model is proposed. In the statistical computation model, the CPU clock is configured to save more energy, thus providing a statistical QoS guarantee. The traditional transmission rate is provided with a statistical delay exponent for QoS guarantee in the statistical transmission model. MINLP (Mixed Integer Non-Linear Program) is then formulated with statistical delay constraint for task offloading. The statistical delay constraint is then converted to the number of CPU cycles and constraints on statistical delay using the probability and queue theory. A holistic task offloading algorithm is proposed. The first resource allocation problem is solved to achieve offloading decisions. Efficiency is met by convergence and scalability. An algorithm with these conditions into consideration will provide a solution with much accuracy and efficiency [32].
