Byzantine fault tolerant systems behave correctly when no more than f out of 3f + 1 replicas fail. When there are more than f failures, traditional BFT protocols make no guarantee...
Fault tolerance is an important issue for large machines with tens or hundreds of thousands of processors. Checkpoint-based methods, currently used on most machines, rollback all ...
Reliability is a key issue of the Service-Oriented Architecture (SOA) which is widely employed in critical domains such as e-commerce and e-government. Redundancy-based fault tole...
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typi...
While extensive studies have been carried out in the past several years for many sensor applications, they cannot be applied to the network with extremely low and intermittent con...
