Aspect Oriented Modeling

Software fault tolerance makes system complicated by means of diverse fault-tolerant mechanisms. Aspect-oriented programming has been confirmed as a well suited candidate to ease the problem. However, most of the existing works only focus on implementation level. This paper proposes an AOFTM model for aspect-oriented fault tolerance modeling with Coloured Petri nets at design level. Moreover, the weaving mechanism formally defined conducts the way to derive a woven net from AOFTM. A case study presents how AOFTM works, and its properties are analyzed using the CPN Tools.

This chapter resumes our survey of application-level fault-tolerance protocols considering approaches based on aspect-oriented programming. Aspect-compliant programming languages allow a source code to be regarded as a pliable web that the designer can weave so as to specialize or optimize towards a certain goal without having to recode it. This useful property keeps concerns separated, bounds complexity, and enhances maintainability. Aspect programs may be used for different objectives, including non-functional properties such as dependability. To date, it is not known whether aspect-orientation will actually provide satisfactory solutions for fault-tolerance in the application layer. Some researchers believe this is not the case (Kienzle & Guerraou, 2002)—at least for some fault-tolerance paradigm. Some preliminary studies have been carried out (for instance in (Lippert & Videira Lopes, 2000)), but no definitive word has been said on the matter. It is our belief that, at least for some paradigms, aspects may reveal themselves as invaluable tools to engineer the application-level of fault-tolerance services. For this reason their approach is described in this chapter.

Load balancing makes cloud computing greater knowledgeable and could increase client pleasure. At reward cloud computing is among the all most systems which offer garage of expertise in very lowers charge and available all the time over the net. However, it has extra vital hassle like security, load administration and fault tolerance. Load balancing inside the cloud computing surroundings has a large impact at the presentation. The set of regulations relates the sport idea to the load balancing manner to amplify the abilties in the public cloud environment. This textual content pronounces an extended load balance mannequin for the majority cloud concentrated on the cloud segregating proposal with a swap mechanism to select specific strategies for great occasions.

Tolerance Approach

In this study, satellite formation flying guidance in the presence of under actuation using inter-vehicle Coulomb force is investigated. The Coulomb forces are used to stabilize the formation flying mission. For this purpose, the charge of satellites is determined to create appropriate attraction and repulsion and also, to maintain the distance between satellites. Static Coulomb formation of satellites equations including three satellites in triangular form was developed. Furthermore, the charge value of the Coulomb propulsion system required for such formation was obtained. Considering Under actuation of one of the formation satellites, the fault-tolerance approach is proposed for achieving mission goals. Following this approach, in the first step fault-tolerant guidance law is designed. Accordingly, the obtained results show stationary formation. In the next step, tomaintain the formation shape and dimension, a fault-tolerant control law is designed.
