Privacy-preserving edge computing offloading scheme based on whale optimization algorithm

Abstract Aiming at the problem of user’s task offloading in mobile edge computing and potential leakage location privacy during process, a privacy-preserving scheme based on whale optimization algorithm is proposed. Using differential technology to obfuscate user's information, user can make decisions according obfuscated distance. Considering delay, energy consumption, their weighted sum, modeled as convex problem. Then, adopted solve this achieve balance between protection resource consumption. Experiments are conducted verify relationship degree leakage, computation-offloading cost real distance, impact factor, respective weights time delay consumption The experimental results show that proposed paper has good performance terms protection.
