Disruption Tolerance

Disruption tolerance is the ability of a system to tolerate disruptions in connectivity among its components. Disruption tolerance is a superset of tolerance of the environmental challenges: weak and episodic channel connectivity, mobility, delay tolerance, as well as tolerance of power and energy constraints.

Abstract: "Delay-tolerant Networking has been discussed for mobile environments, both with predictable (e.g., between buses) and unpredictable opportunistic (e.g., between people) contact schedules. While some research projects have envisioned the larger scale use of DTNs to perform message forwarding based upon social interactions between humans, the geographic dimension of simulations has mostly been limited to rather local areas such as (parts of) cities or modestly sized areas covered by public transportation. In this paper, we explore how messages could be carried over a realistic large scale global network, between airports based upon scheduled flight connections. We investigate the interaction with different routing protocols, the impact of scheduling uncertainties, and the limiting factors by means of simulations and analysis. While we do not consider in depth the integration of aerial-carrier-based DTN message delivery into regional and local social networks, we provide some initial approximation on this subject and discuss some potential roles for message forwarding based upon mass transportation."

Abstract: "In this paper the synthetic storm technique is evaluated on an event-by-event basis by comparing measured 40 GHz satellite link attenuation series with calculated series using concurrent rain intensity recordings. The results of a limited validation are presented."

Notes: Useful reference for Storm front modeling used in the Millimeter wave mesh networks project. It should be useful to look at the rest of the papers in Cost Action 280 - "Propogation Impairment Mitigation for Millimeter Wave Radio Systems".
