By increasing, the complexity of chips and the need to integrating more components into a chip has made network –on- chip known as an important infrastructure for network communications on the system, and is a good alternative to traditional ways and using the bus. By increasing the density of chips, the possibility of failure in the chip network increases and providing correction and fault tol...

The incorporation of fault tolerance techniques into robot systems improves the reliability, but also increases the hardware and computational requirements in the overall system. It is not always clear how to evaluate the merit, orèeectiveness' of diierent fault tolerance approaches for a given application. In this paper, we present a new set of performance criteria designed to measure and comp...

The recursive training algorithm for the optimal interpolative (OI) classification network is extended to include distributed fault tolerance. The conventional OI Net learning algorithm leads to network weights that are nonoptimally distributed (in the sense of fault tolerance). Fault tolerance is becoming an increasingly important factor in hardware implementations of neural networks. But faul...

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...

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...

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)...
