There are many applications in which the reliability of the overall system must be far higher than the reliability of its individual components. In such cases, designers devise mechanisms and architectures that allow the system to either completely
Election algorithms arewidely used in the primary-backup replication, and ithas been proved to be harder than the con- sensus problem. In this paper, the relation between the election problem and the consensus problem is analysed, and a new fault- t
This paper describes an I/O scheme for use in a highspeed bus which eliminates setup and hold time requirements between clock and data by using an oversampling method. The I/O circuit uses a low jitter phase-locked loop (PLL) which suppresses the ef
The problem of choosing the best forwarders in Delay-Tolerant Networks (DTNs) is crucial for minimizing the delay in packet delivery and for keeping the amount of generated traffic under control. In this paper, we introduce sociable routing, a novel
Delay tolerant networks (DTNs) are a special type of wireless mobile networks which may lack continuous network connectivity. Multicast is an important routing function that supports the distribution of data to a group of users, a service needed for
A wide range of fault tolerance methods for FPGAs have been proposed. Approaches range from simple architectural redundancy to fully on-line adaptive implementations. The applications of these methods also differ; some are used only for manufacturin
The performance of portable and wearable biosensors is highly influenced by motion artifact. In this paper, a novel real-time adaptive algorithm is proposed for accurate motion-tolerant extraction of heart rate (HR) and pulse oximeter oxygen saturat
The standardization of the IP protocol and its mapping into network-specific link-layer data frames at each router as required supports interoperability using a packet-switched model of service. Although often not explicitly stated, a number of key
