The invention discloses a
delay and
energy consumption joint optimization MEC computing unloading method, and aims to solve the problems that in computing unloading of multiple users to multiple servers of an MEC,
server resources are scrambled by unloading requests of the users, optimal unloading occurs, the effective
utilization rate of the resources is low, the unloading
service quality is poor and the like. According to the method,
delay and
energy consumption serve as constraints, an unloading
cost evaluation model is constructed and calculated, in order to determine an unloading target, a
server selection operator is designed, a
server meeting task
response delay is preferentially selected to execute unloading calculation, and an improved difference
algorithm with
response delay,
energy consumption and
server load serving as fitness functions is designed; an unloading decision with a low
adaptive value is searched, and low-overhead and load-balanced efficient calculation unloading is realized;
simulation experiments prove that the method reduces the
delay and energy consumption of the
mobile edge computing network, improves the task satisfaction
response delay rate, balances the load of the server, and improves the
user satisfaction, energy consumption efficiency and stability of the
mobile edge computing system.
