An online fault tolerant routing algorithm for 2D Mesh Networks-on-Chip is presented in this work. It combines an adaptive routing algorithm with neighbor fault-awareness and a new traffic-balancing metric. To be able to cope with runtime permanent and temporary failures that may result in message corruption, message loss or deadlocks, the routing algorithm is enhanced with packet retransmissio...

Reliable broadcast is an important primitive in wireless mesh networks (WMNs) for applications such as software upgrade, video downloading, etc. However, due to the lossy nature of wireless link, it is not trivial to achieve the reliability and efficiency at the same time. In this paper, we put forward R-Code, a reliable and efficient broadcast protocol based on intra-flow network coding. The k...

Backscatter radio communication typically has less reliability than conventional links, hindering adaptation. Retrodirective arrays have been shown to enhance the link with gain and a recently-observed resistance small-scale fading. However, statistical advantages of retrodirective backscatter channels only theoretically studied for ideal, infinite arrays. This article studies practical finite ...

proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...

Mobile ad-hoc networks (MANETs) are dynamic by nature; this dynamism comes from node mobility, traffic congestion, and other transmission conditions. Metrics to evaluate the effects of those conditions shine a light on node's behavior in an ad-hoc network, helping to identify the node or nodes with better conditions of connection. In this paper, we propose a relative index to evaluate a single ...

The usability of wireless sensor networks in modern applications requires the fulfillment of dynamic Quality of Service (QoS) requirements that can only be met in a reactive manner by the introduction of composite routing metrics, capturing several distinct network characteristics. However, combining routing metrics is neither a trivial nor an arbitrary task, given the routing protocol requirem...

In wireless sensor networks, a good cost metric encapsulating wireless link quality is essential to an energy-efficient routing topology. For many wireless network scenarios, rapid variation in the channel precludes an efficient mechanism for knowing instantaneous link quality at the time of transmission, thus making it difficult to estimate the instantaneous value of the cost metric. This pape...

This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, confidentiality, integrity, maintainability, etc. Basic definitions are given first. They are then commented upon, and supplemented by additional definitions, which address the threats to dependability (faults, errors, failures), and ...
