D-FLASH: Dynamic Fault Localization And Self-Healing for Battlefield Networks

The necessity for mechanisms that provide service survivability (i.e., seamless restoration of networking services affected by random failures) in battlefield networks, is both obvious and critical. This paper addresses the fundamental challenge of providing service survivability via efficient fault localization and self-healing techniques in the Army’s Future Battlefield Networks, examples of which include the FCS, WIN-T and Objective Force Nets. More specifically, we develop efficient fault diagnosis techniques and self-healing mechanisms in order to both rapidly and accurately pin-point the root cause of a problem and to provide uninterrupted services amidst unforeseen failures, in the ad-hoc battlefield environment.
