Fault-tolerance and network routing have been among the most widely studied topics in the research of parallel processing and computer networking. A fault- tolerant routing algorithm should guarantee the delivery of messages in the presence of faulty components. In this paper, we present a comparative performance study of nine prominent fault-tolerant(More)
In recent years, the Elliptic Curve Cryptosystem (ECC) has attracted a great deal of attention due to its advantages. In this paper, a new ECC based scheme in a hierarchical mobile agent framework is presented. In the proposed scheme legality of agents is verified by hosts to avoid the masquerade attack. Analyzing the security criteria and performance(More)
Parallel computers, such as multiprocessors system-on-chip (Mp-SoCs), multicomputers and cluster computers, are consisting of hundreds or thousands multiple processing units and components (such as routers, channels and connectors) connected via some interconnection network that collectively may undergo high failure rates. Therefore, these systems are(More)
One of the fundamental problems in parallel computing is how to efficiently perform routing in a faulty network each component of which fails with some probability. This paper presents a comparative performance study of ten prominent adaptive fault-tolerant routing algorithms in wormhole-switched 2D mesh interconnect networks. These networks carry a routing(More)
Several analytical models have recently been proposed for circuit-switched interconnect networks under the uniform traffic pattern. However, there has been hardly any model reported yet that deals with other important non-uniform traffic patterns, such as hot-spots. This paper presents a new mathematical model to capture the mean message latency in the(More)
