In this paper, we present Intercom, a simulator framework that provides separate components to address the interdependent aspects of IoT systems, such as sensing, physical interaction, wireless communication, and computation. We initially evaluate a scalable sensing and communication model, which simulates wireless signal strength measurements with an average error of 6.1dBm.
From a system perspective, cost effectiveness and high-precision location information are important in wireless sensor networks (WSNs). Since a weighted centroid localization (WCL) algorithm can reduce hardware installation cost and guarantee localization accuracy, this algorithm is considered as one of the promising localization algorithms for WSNs. In this paper, we propose a test node-based WCL...
Wireless Sensor Networks(WSNs) consists of hundreds of nodes which are of low power, low cost, and tiny devices. The main functionality of these nodes is to sense the environment and send the sensed data to the observer. In order to validate and get the significance of sensing data, location information of the sensor node needs to be combined with the sensed data. In addition to this, there are many...
We present the architecture and design of a general purpose robotics development kit, called X10ABOT, which aims to facilitate the rapid development of robotic solutions to a wide variety of problems. Robotics kits of this sort are usually aimed at casual hobbyists and children, and as a result, usually have severe limitations in the number of sensors and actuators that they can manage. In contrast,...
In this paper we present a cycle-accurate performance analysis method for real-time systems that incorporates the following phases: (a) profiling SW components at high accuracy, (b) modeling the obtained performance measurements in MARTE-compatible models, (c) generation, scheduling analysis and simulation of a system model, (d) analysis of the obtained performance metrics and (e) a subsequent architecture...
The paper suggests the methodology for validation of designed systems and experiments through the use of the developed simulation tools and interactive models. The primary idea is prototyping on the basis of virtual visual samples imitating interacting physical objects. The desired electronic functionality is implemented in reconfigurable hardware and, therefore, can easily be changed, which significantly...
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...
