Performance of a Heterogeneous Computing Environment (HCE) mainly depends on the efficiency of application workflow scheduling algorithms. Achieving high efficiency of application workflow scheduling algorithms in HCE is an NPComplete problem. A novel application workflow scheduling algorithm called Heterogeneous Dynamic List Task Scheduling (HDLTS) for HCE is proposed in this paper. The functionality...
Cloud computing model provides global and ondemand access to resources in a seamless manner with minimal interaction with the service provider. A typical cloud data center consists of several computational resources interconnected with each other through high-speed networks. In cloud the program execution can be visualized as a collection of multiple tasks represented by Directed Acyclic Graph (DAG)...
With the progressive development of information and communication technologies, we are now forming a new world called hyperworld that is composed by the cyber world and the physical world with various digital explosions including data, connectivity, service and intelligence. Therefore, Cyber-I has been proposed, which is a real individual's counterpart in cyberspace, and is to create a unique, digital,...
Network lifetime maximization with guaranteed coverage is an important issue in wireless sensor networks. Based on our recently proposed confident information coverage (CIC) model, this paper studies the multi-modal confident information coverage (M2CIC) problem. Assuming that each node is equipped with different types of sensors, the objective is to schedule the multi-modal sensors’ activity, such...
Currently, most tasks submitted to earth observation satellites (EOSs) are with deadlines, to satisfy users' timing requirements. Especially, in emergency, the timing needs are more apparent. Unfortunately, traditional scheduling algorithms do not efficiently deal with this issue. Hence, it is nontrivial to propose a real-time scheduling algorithm for multiple EOSs. In this paper, we establish a multi-objective...
In multiprocessor systems, passive replication is a technique that trades processing power for increased reliability. One approach of passive replication, called primary-backup task scheduling, is often used in real-time multiprocessor systems to ensure that deadlines are met in spite of faults. Briefly, it consists in scheduling a secondary task conditionally, in such a way that the secondary task...
