Reactive/proactive connectivity management in a tactical service-oriented infrastructure

This paper introduces a model to represent the information systems using a tactical service-oriented infrastructure (TSI) together with the orchestrations of core services providing the reactive/proactive connectivity mechanisms within TSIs in/out chains. The model was instantiated with services realizing an algorithm behaving differently under stable or unstable network conditions. A quantitative analysis was performed over simulated results from a network using ns-3 and OLSRv2 with nodes organized in three mobility patterns: random, group and grid. The results suggest that connectivity graph metrics such as link changes, link duration and path availability can be used to trigger a cross-layer and service-oriented mechanism.
