In this paper, a project-based learning strategy is proposed as a pedagogical tool for embedded system education targeting for undergraduate engineering students. The proposed project-based learning can motivate students to integrate and formulate the multi-disciplinary knowledge previous learned into a real-world embedded system project development. To(More)
In this paper, a reinforcement learning-based throughput on demand (ToD) provisioning dynamic power management method (RLTDPM) is proposed for sustaining perpetual operation and satisfying the ToD requirements for today's energy harvesting wireless sensor node (EHWSN). The RLTDPM monitors the environmental state of the EHWS and adjusts their operational(More)
Surface plasmon resonance (SPR) sensing and an enhanced data analysis technique are used to obtain precise predictions of the dielectric constant and thickness of a nanolayer. In the proposed approach, a modified analytical method is used to obtain initial estimates of the dielectric constants and thicknesses of the metal film and a nanolayer on the sensing(More)
A reinforcement learning (RL) method for Quality of Service (QoS)-aware power management (PM) of an energy harvesting wireless sensor network, named QoS-aware RLPM, is proposed in this paper. The RL environment for each sensor node is represented by the observable measurements of harvesting energy and residual energy stored in the battery. To achieve(More)
Currently, several smart phones have GPS receivre built- in, such as Motorola E1000, HP iPAQ 6515 and Mio A700. Equipped with GPS receiver, the mobile phone has enabled its owner to become a personal position locator. The proposed project GPSenseCar is to use the WiFi smart phone with the built-in GPS receiver to develop a collision avoidance support system(More)
In this paper, embedded software engineering approach is employed for the development of a SIP-based VoIP server. Signaling control functions of SIP servers are integrated and implemented in an embedded system platform. This embedded SIP server also serves as network access server (NAS) client to a centralized RADIUS server to provide user's authorization,(More)
Use of adaptive energy management strategies is essential in improving energy utilization, efficiency, and sustainable operation of embedded systems. Accordingly, this paper presents embedded system applications, which are suitable for employing adaptive energy management utilized reinforcement learning. We proposed rewarding function for embedded system(More)
