Human immune system inspired architecture for self-healing digital systems

Abstract

This paper proposes an architecture for implementing self-healing digital systems. The adopted self-healing mechanism is inspired by the human immune system. A digital system based on the proposed architecture is composed of a number of functional cells that are interconnected to perform a desired function. As in the immune system, the error detection in the cell based digital system is done without using any centralized fault detection mechanism. Once a faulty cell is identified a spare cell replaces it; the spare cells are distributed throughout the system.
