nd planning of contingency responses Adaptation and evolution. To manage current and future threats for the network The Survivable Mobile Wireless Networking project introduced the following techniques for managing survivability, with a key focus on mobile wireless networks (Survivable Mobile Wireless Networks: Issues, Challenges, and Research Directions, by James P.G. Sterbenz and Rajesh Krishnan): Proposed use of adaptive and agile networking concepts where the link layers are aware of the environmental conditions and adapt to adjust operational parameters to enhance survivability, for example, selection of alternate frequencies based on feedback from channels. Support for routing techniques that uses geographic knowledge to enhance survival operations, such as use of alternate routing nodes when information about geographic redundancy is available. Adaptive networking could also include selective use of MAC (Medium Access Control) and network layer parameters to help adapt to varying communication layer requirements. For example, at some instant, ensuring correctness of delivery at lower performability regions may be the requirement, while in some other conditions maximizing throughput with low RTT could be the goal. Usage of satellite communication to enhance and provide connectivity in scenarios to exploit specific requirements is also part of the proposal. This includes using satellites to connect network segments that have become isolated and also exploiting specific availability and dependability windows provided by the satellite communication to be able to perform multicast operations to a large set of listener nodes for reasons of security and communication. The ResiliNets initiative argues for a strategy based on the following axioms: Faults are inevitable Understanding normal operations is necessary Expectations and preparation for adverse events and conditions is necessary Response to adverse events and conditions is necessary The resilience strategy of ResiliNets includes dual components: Defend, De
