Datacenter networks are becoming crucial foundations for our information technology based society. However, commercial datacenter infrastructure is often unavailable to researchers for conducting experiments. In this work, we therefore elaborate on the possibility of combining commercial hardware and simulation to illustrate the scalability and performance of datacenter networks. We simulate a Datacenter...
A wireless sensor network (WSN) is a collection of sensor nodes which can monitor the physical activities and attributes of a whole spectrum of objects and environments. The purpose of collecting this data and processing it in a meaningful manner requires that it adds significant value to the end user. WSN are deployed ever more frequently and applications vary from providing an early alert system...
The recent growth of interest for in-memory databases poses the question on whether established prediction methods such as response surfaces and simulation are effective to describe the performance of these systems. In particular, the limited dependence of in-memory technologies on the disk makes methods such as simulation more appealing than in the past, since disks are difficult to simulate. To...
In this work, we focus on the problem of virtual machines (VMs) placement in geographically distributed data centers, where tenants may require a set of networking VMs. The aim of the present work is to plan and optimize the placement of tenant's VMs in a distributed Cloud environment while considering location and system performance constraints. Thus, we propose ILP formulations which have as objective...
From a single SoC to a network of embedded devices communicating with a backend cloud-computing server, emerging classes of embedded systems feature an increasing number of heterogeneous components that operate concurrently in a distributed environment. As the scale and complexity of these systems continues to grow, there is a critical need for scalable and efficient simulators. We propose a networked...
The management of multiple systems such as machine tools, vehicles, aircraft, among others, results in a very intense flow of data between the server and embedded systems, using wired and/or radio frequency structures, demanding performance and interest in real time systems. The objective of this study is to propose a low cost scalable architecture for embedded applications, using pools of personal...

Recently mobile robots act in various situations such as disaster areas, office buildings, factories and homes. When these new mobile robots are released, they should be confirmed to work correctly and safety from evaluation. In this paper, we propose large-scale simulation environment of mobile robots on StarBED which is a large-scale networked testbed. By using the simulation environment, we could...
Petascale computing requires I/O subsystems that can keep up with the dramatic computing power demanded by such systems. TOP500.org ranks top computers based on their peak compute performance, but there has not been adequate investigation of the current state-of-the-art and future requirements of storage area networks that support petascale computers. Dependable scaling of an I/O subsystem to support...
