Abstract

In this paper, we propose Arbiter-Recall, which is a new kind of function code update management. When a function requires updating, Arbiter-Recall adaptively selects an energy-efficient method, deciding between a remote-call and a local-call after updating a function. The run-time decision is made by analyzing the cost of a remote-call, and a local-call with dynamic function update in terms of the energy consumption. Simulation results show that Arbiter-Recall significantly reduces energy consumption compared to existing schemes.
