- Adaptive Correctness Monitoring for Wireless Sensor Networks Using Hierarchical Distributed Run-Time Invariant Checking
- This paper presents a hierarchical approach for detecting faults in Wireless Sensor Networks (WSNs) after they have been deployed. The developers of WSNs can specify "Invariants" that must be satisfied by the WSNs. It presents a framework, Hierarchical SEnsor Network Debugging (H- SEND), for lightweight checking of invariants. H-SEND is...

- It's the Sun's fault
- OK, we finally know the REAL reason for global warming: it's the Sun's fault!http://news.bbc.co.uk/1/hi/sci/tech/56456.stmI think we should start a movement to banish the Sun from our Solar System to protect the planet. But we have to act quickly, before it's too late. Call your Government Representative today!Puzzlement.Maxwell posted...

- They think I'm relaying?
- We recently upgraded to Exchange 2003 on a Win 2003 server. Since that upgrade (from 5.5 on Win2k), I've had this happen several times. Not sure if it's a problem on my end, or other people tightening up, or what. I made sure we're not set up...

- fault-Scalable Byzantine fault-Tolerant Services
- A fault-scalable service can be configured to tolerate increasing numbers of faults without significant decreases in performance. The Query/Update (Q/U) protocol is a new tool that enables construction of fault-scalable Byzantine fault-tolerant services. The optimistic quorum-based nature of the Q/U protocol allows it to provide better throughput and fault-scalability than...

- IBM Tivoli Workload Scheduler 8.2: Switch fault Tolerance
- Switch Fault Tolerance offers additional resilience for the data being transferred. Switch Fault Tolerance is designed to improve fault tolerance in an IBM Tivoli Workload Scheduler network. This feature removes a single point of failure and the possible loss of messages in the event a domain manager should fail. Switch...

- Toward Sharing Reasoning to Improve fault Localization in Spreadsheets
- Although researchers have developed several ways to reason about the location of faults in spreadsheets, no single form of reasoning is without limitations. Multiple types of errors can appear in spreadsheets, and various fault localization techniques differ in the kinds of errors that they are effective in locating. Because end...

- A Kernel-Based Communication fault Injector for Dependability Testing of Distributed Systems
- Software-implemented fault injection is a powerful strategy to test fault-tolerant protocols in distributed environments. This paper presents ComFIRM, a communication fault injection tool developed which minimizes the probe effect on the tested protocols. ComFIRM explores the possibility to insert code directly inside the Linux kernel in the lowest level of...
