Abstract: Cyber Physical Systems (CPSs) integrate networked embedded computation systems with real-world physical installations. Programming of CPSs is not trivial, since CPSs combine traditional programming challenges and real-world timing, concurrency, and communication. This paper shows how a programming framework that allows students to implement and test CPS control programs in their Internet browsers, can improve both […]

Abstract: The smart building, as an application of the cyber-physical systems (CPSs), plays an important role in everyday lives of people. Thermal comfort and energy efficiency are primary goals for HVAC systems in smart buildings. Since the controllers of the HVACs heavily rely on data of sensors that are deployed in the buildings, temporary or permanent […]

Abstract: A good cyber-physical-systems (CPS) design methodology must conduct trade-off analysis of both the physical characteristics of the CPS as well as its cyber sub-system in a holistic manner. This paper presents a design space exploration (DSE) approach for CPSs that emphasizes the variabilities of the physical subsystem and control aspects of the system. We propose […]

Abstract: The Cyber-Physical System (CPS) is a term describing a broad range of complex, multi-disciplinary, physically-aware next generation engineered system that integrates embedded computing technologies (cyber part) into the physical world. In order to define and understand CPS more precisely, this article presents a detailed survey of the related work, discussing the origin of CPS, the […]

ACM SIGBED Review, vol. 11, num. 4, 2014
Abstract: In this paper we outline the Adaptive Resource Allocation Protocol (ARAP) as an improved resource synchronization algorithm for hierarchically scheduled real-time systems. ARAP exploits knowledge about task utilization, using a proportional- integral-derivative (PID) controller, to estimate required resource bandwidth and improve scheduling decisions. Our analysis and experiments with RTSIM show that ARAP provides better temporal […]

Abstract: The Constrained Application Protocol (CoAP) is a promising candidate for future smart city applications that run on resource-constrained devices. However, additional security means are mandatory to cope with the high security requirements of smart city applications. We present a framework to evaluate lightweight intrusion detection techniques for CoAP applications. This framework combines an OMNeT++ simulation […]

Abstract: The  demand  for  compute  cycles  needed  by embedded  systems  is  rapidly  increasing.  In  this  paper,  we introduce  the  XGRID  embedded  many-core  system-on-chip architecture.  XGRID  makes  use  of  a  novel,  FPGA-like, programmable interconnect infrastructure, offering scalability and  deterministic  communication  using  hardware  supported message  passing  among  cores.  Our  experiments  with  XGRID are  very  encouraging.  A  number  of  […]

Abstract: In hardware/software co-design for a multi-core platform, a crucial role is played by fast and accurate early performance estimation. One type of such estimation that is as fast as native simulation, cycle-approximate and applicable to both software and custom hardware is Transaction Level Model (TLM) Estimation that depends on TLM simulation. For every platform selection […]

Abstract: This paper presents hierarchy-aware mapping of a pipelined application to a given heterogeneous platform. The applications we target are executed in a pipelined manner and can be captured with a Model of Computation (MoC) with explicit representations of pipelined execution. Our optimization goal is to minimize execution time. It is crucial to balance the pipeline […]

Abstract: Online courses have been debated among the UC regents, numerous college administrators, faculty, and students. On one hand, online education can reduce overhead while enrolling more students. Administration wants to enroll more students while incurring minimal overhead costs. However, simply translating the classroom lectures and materials to an online environment does not necessarily produce equivalent […]
