Wireless sensor networks consist of a large number of small, low-power sensors that communicate through wireless links. Wireless sensor networks for healthcare have emerged in recent years as a result of the need to collect data about patients’ physical, physiological, and vital signs in the spaces ranging from personal to hospital and availability of the(More)
With advance in technology and working frequency reaching gigahertz, designing and testing interconnects have become an important issue. In this paper, we proposed a BIST-based boundary scan architecture to at-speed test of crosstalk faults for inter-switch communication links in network on chip. This architecture includes enhanced cells intended for MVT(More)

Pourfak In recent years wireless mesh networks have been deployed and grown in popularity in many metropolitan areas. The deployment of such networks has allowed clients to gain access to(More)
In general, distributed flexible manufacturing systems (FMS) scheduling problems are more complicated than the classical FMS scheduling, because it has to focus on two different issues: first, allocation of jobs to suitable factories and second, determination of the corresponding production scheduling in each factory. On the other hand in distributed FMS(More)
Task scheduling is essential for the suitable operation of multiprocessor systems. The aim of task scheduling is to determine an assignment of tasks to processors for shortening the length of schedules. The problem of task scheduling on multiprocessor systems is known to be NP-complete in general. Solving this problem using by conventional techniques needs(More)
In recent years, grid technology has had such a fast growth that it has been used in many scientific experiments and research centers. A large number of storage elements and computational resources are combined to generate a grid which gives us shared access to extra computing power. In particular, data grid deals with data intensive applications and(More)
In this paper we present a novel congestion control scheme based on fuzzy logic systems for a wireless sensor network (WSN). In sensor networks existence of malicious nodes is undeniable. These nodes aggravate congestion problem by diffusing useless packets. In our approach using in-network fuzzy based processing, each node monitors the behavior of its(More)
The goal of grid computing is to aggregate the power of widely distributed resources. Considering that the probability of failure is great in such systems, fault tolerance has become a crucial area in computational grid. In this paper, we propose a new strategy named RFOH for fault tolerant job scheduling in computational grid. This strategy maintains the(More)
The increasing demand on execution of large-scale Cloud workflow applications which need a robust and elastic computing infrastructure usually lead to the use of high-performance Grid computing clusters. As the owners of Cloud applications expect to fulfill the requested Quality of Services (QoS) by the Grid environment, an adaptive scheduling mechanism is(More)
One of the most important challenges in a densely wireless sensor network (WSN) with potential congestions and packet loss is dissemination of distrusted packets. In this paper we present FCCTF: Fairness Congestion Control for a disTrustful WSN using Fuzzy logic. FCCTF increases each node capability for detecting and isolating malicious nodes in order to(More)
