Due to recent advances in mobile wireless communication and computing technologies, Mobile Ad hoc Networks (MANETs) have become the network of choice for use in various applications. But this advantage comes with serious security concerns, in particular from a wireless transmission medium perspective where such networks may be subject to data tampering and dropping attacks. This paper enhances a recently proposed AODV-based protocol named Highly Secured Approach against Attacks on MANETs (HSAM) that deals with this issue in at least two ways: (a) by performing for the first time a simulation study of the HSAM protocol;(b) by introducing a more efficient approach to securing the routes in the route selection phase of the HSAM scheme. Simulation results are provided, showing that the proposed enhanced HSAM scheme (so-called E-HSAM) outperforms HSAM in terms of packet delivery ratio, throughput rate, and number of broken links;chosen as performance metrics, when malicious nodes are present in the network. © 2012 IEEE.

In this paper, we consider a two-dimensional (2-D) formation problem for multi-agent systems subject to switching topologies that dynamically change along both a finite time axis and an infinite iteration axis. We present a distributed iterative learning control (ILC) algorithm via the nearest neighbor rules. By employing the 2-D approach, we develop both the asymptotic and exponentially fast convergence of our formation ILC, which can be guaranteed by conditions in terms of the spectral radius and the matrix norms, respectively.

The auto-design of electronic circuits for the next generation Information Technology (IT) computing environments is currently one of the most extensively studied issues in the field of evolvable hardware (EHW) architectures. It aims to improve the reliability and fault-tolerance of hardware systems using embedded techniques. As the scalability of logic circuits becomes larger and more complex nowadays, its auto-design is more and more difficult. In order to improve the efficiency and the capability of digital circuit auto-design, in this paper, a multi-objective simulated annealing (MSA)-based increasable evolution approach is proposed in an embedded system. First, an extended matrix encoding method is used to indicate the potential performance of a circuit. Therefore, the risk of deleting a circuit with a good developing potential during evolution can be reduced. Second, we consider each output of a digital circuit as an objective, and MSA is designed for digital logic circuits with gradual evolution scheme. In the process of evolution, each objective is evolved in parallel with adaptive mechanism of neighborhood and a performance evaluation. Finally, a framework of online evolution with macro-blocks is employed to implement MSA on a field-programmable gate array efficiently and securely. In our experiments, six arithmetic circuits are designed to assess the performance of MSA with gate-level and function-level approaches comparing to other algorithms. The comparison results show that our method is very efficient in the auto-design of EHW. © 2010 John Wiley & Sons, Ltd.

Working IEEE/IFIP Conference on software Architecture

Business and design decisions regarding software development should be based on data, not opinions among developers, domain experts or managers. The company running the most and fastest experiments among the customer base against the lowest cost per experiment outcompetes others by having the data to engineer products with outstanding qualities such as power consumption and user experience. Innovation experiment systems for mass-produced devices with embedded software is an evolution of current R&D practices, going from where innovations are internally evaluated by the original equipment manufacturer to where they are tried by real users in a scale relevant to the full customer base. The turnaround time from developing and deploying an embedded product to getting customer feedback is decreased to weeks, the limit being the speed of the software development teams. The paper presents an embedded architecture for realising such a novel innovation experiment system based on a set of scenarios of what to evaluate in the experiments. A case is presented implementing an architecture in a prototype in-vehicle infotainment system where comparative testing between two software alternatives was performed.

Finite-difference, stencil-based discretization approaches are widely used in the solution of partial differential equations describing physical phenomena. Newton-Krylov iterative methods commonly used in stencil-based solutions generate matrices that exhibit diagonal sparsity patterns. To exploit these structures on modern GPUs, we extend the standard diagonal sparse matrix representation and define new matrix and vector data types in the PETSc parallel numerical toolkit. We create tunable CUDA implementations of the operations associated with these types after identifying a number of GPU-specific optimizations and tuning parameters for these operations. We discuss our implementation of GPU auto tuning capabilities in the Orio framework and present performance results for several kernels, comparing them with vendor-tuned library implementations.

International Symposium on software Reliability engineering (ISSRE)

Objective: Defect classification is an essential part of software development process models as a means of early identification of patterns in defect inflow profiles. Such classification, however, may often be a tedious task requiring analysis work in addition to what is necessary to resolve the issue. To increase classification efficiency, adapted schemes are needed. In this paper a light-weight defect classification scheme adapted for minimal process footprint -- in terms of learning and classification effort -- is proposed and initially evaluated. Method: A case study was conducted at Volvo Car Corporation to adapt the IEEE Std. 1044 for automotive embedded software. An initial evaluation was conducted by applying the adapted scheme to defects from an existing software product with industry professionals as subjects. Results: The results showed that the classification scheme was quick to learn and understand -- required classification time stabilized around 5-10 minutes already after practicing on 3-5 defects. The results also showed that the patterns in the classified defects were interesting for the professionals, although in order to apply statistical methods more data was needed. Conclusions: We conclude that the adapted classification scheme captures what is currently tacit knowledge and has the potential of revealing patterns in the defects detected in different project phases. Furthermore, we were, in the initial evaluation, able to contribute with new information about the development process. As a result we are currently in the process of incorporating the classification scheme into the company's defect reporting system.

Modern technical systems are increasingly built to exhibit self-x properties as, e.g., self-healing or self-optimization. For this, they require adaptation at runtime. This is even true for embedded or mechatronic systems which often operate in safety-critical environments. There, the effects of the adaptation with respect to safety must be analyzed carefully. However, not all parameters needed for safety analyses, e.g., the concrete system architecture, are known at design time. Consequently, safety analyses need to be executed during runtime. Current approaches of runtime safety analysis typically react to anomalies that already occurred in the system. Thus, unsafe system states cannot be excluded completely. We present a runtime safety analysis that prevents system states with an unacceptable risk that have not yet occurred. For this, we generate the reachable component structures at runtime and analyze them with respect to risk. The system is modified such that component structures with an unacceptable risk are not reachable any more and are thus prevented.
