A method is proposed to estimate the fault tolerance of feedforward Artificial Neural Nets (ANNs) and synthesize robust nets. Fault models are presented and a procedure is developed to build fault tolerant ANNs by replicating the hidden units. Based on this procedure, metrics are devised t o quantify the fault tolerance aa a function of redundancy. A significant amount of redundancy is shown to...

Please cite this article in press as: P.M. Yaghini Syst. Architect. (2010), doi:10.1016/j.sysarc.201 This paper presents comparison of transient fault effects in an asynchronous NoC router and a synchronous one. The experiment is based on simulation-based fault injection method to assess the fault-tolerant behavior of both architectures. The effort has been accomplished by employing fault injec...

ÐThe current fault-tolerant routing methods require extensive changes to practical routers such as the Cray T3D's dimension-order router to handle faults. In this paper, we propose methods to handle faults in multicomputers with dimension-order routers with simple changes to router structure and logic. Our techniques can be applied to current implementations in which the router is partitioned i...

The failure-prone complex operating environment of a standard multi-robot application dictates some amount of fault-tolerance to be incorporated into the system. Being able to identify the extent of fault-tolerance in a system would be a useful analysis tool for the designer. Unfortunately, it is difficult to quantify system fault-tolerance on its own. A more tangible metric for evaluation is t...

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...

Existing hierarchical routing schemes, employing distance vector and link state routing algorithms, require the exchange of routing information for the construction and maintenance of routing tables [1]. As networks increase in size, the memory requirements for the routing tables and the time taken to search the tables increase proportionally [11]. Further, as the popularity of computer network...

Abstract: In this chapter, we introduce fault tolerance in Wireless Sensor Networks. Firstly, we start with a short description of sensor networks, fault tolerance and its different techniques. Then we discuss the different phases of fault tolerance (fault models, fault detection and identification at five levels of abstractions (physical, hardware, middleware, system software and applications)...

In many application domains there is an increasing trend for mixed-criticality systems with functions of different assurance levels on shared computing platforms. Today’s CAN-based platforms do not support the requirements of mixed-criticality systems. A single CAN bus provides low cost, real-time support and flexibility for applications where the communication service is not safety-relevant. F...
