Secure Wireless Fault Tolerant Networks Introduction: Swift is aWireless Networking project at the Computer Science Department of UC Riverside. The project is funded by Defense Advanced Research Projects Agency (DARPA). Swift is aimed at developing novel approaches to enhance the security, Fault-tolerance and Tunability of the Mobile Wireless Ad Hoc Environment. Reconfigurability: Unlike most other work on fault tolerance, SWIFT also addresses reconfigurability at higher system layers. This enhances the degree of flexibility available during the strategic and tactical planning process, not simply during the implementation. SWIFT builds frameworks for the high-level specification of the communication and organizational entities needed to implement a given deployment, the inter-relationships between these entities, and the automated assignment of the roles and tasks defined in the plan to the resources actually available. If changes become necessary after deployment, our work will enhance the ability of the system to automatically reconfigure the earlier assignment of roles and tasks. Tunability: Typically flexibility in role assignment, fault-tolerance, and security characteristics can be achieved at the expense of resources and power. Instead of finding a single point of balance in this spectrum of choices for trading off resources against flexibility, SWIFT can be tuned to operate at different tradeoff points in the spectrum of choices between flexibility and resource consumption. Furthermore, different parts of the infrastructure may operate at different points in a local spectrum of tradeoffs. |
