A Joint Computation Offloading and Resource Allocation Strategy for LEO Satellite Edge Computing System

Abstract

Low Earth Orbit (LEO) satellite edge computing system is becoming an emerging topic and technology aiming to meet the ever-increasing computation requirements in extensive coverage. In this paper, a novel cost model of the system is established firstly, which can be formulated as a mixed integer nonlinear programming problem. And then the problem is decomposed into two sub-problems, i.e. computation offloading problem and resource allocation problem. Furthermore, a joint computation offloading and resource allocation (JCORA) strategy is proposed to tackle the two sub-problems as a whole. Simulation results show that the proposed JCORA strategy can reduce the average cost of system significantly.
