Show moreThis thesis proposes the use of remote laboratory experiments in distance education as a tool to add a reality factor to the distance learning process, thus combining the convenience of distance education with the effectiveness of the traditional physical campus, through its laboratories and technological resources. Moreover, this research studies the different aspects of distance education and remote labs and then provides a proposition to develop an effective remote laboratory setup. Furthermore, it introduces and discusses the different components of a general remote lab experiment and applies the proposed process to an actual remote lab experiment, namely 'The Characteristics of a Resistor'.

Show moreIn the past few years many US institutions of higher education have established virtual classrooms where learners pursue higher education via the Internet. The true challenge in Distance Education however remains; how do students perform real lab experiments--such as electronics over the Internet? To examine this challenge, a survey was conducted on over fifty Web-based educational environments, to assess the shortcomings of laboratory facilities currently available on the Internet. The survey revealed that contemporary labs touted to be virtual environments are merely software simulations. Hence the new idea of a facility that will realistically provide lab experiments over the Internet. With this aim, an innovative system is designed using object-oriented methodologies in Unified Modeling Language to include all aspects of software and hardware. Java/RMI is used as the system's development tool. An experiment to measure the "VI characteristics of a Resistor" is built using National Instruments' DAQ systems. The students can logon through the Internet, register, and perform experiments by sending various current values, and measure the corresponding voltages across a resistor. The results are submitted for grade and the teaching assistant can grade the student after observing the input and output values over the Internet.

Low latency and energy efficient MAC protocols for wireless sensor networks

Abstract/Description
Energy consumption is a critical design issue in Wireless Sensor Networks (WSNs), since sensor nodes are battery operated, and replacing or recharging the battery is usually infeasible. Energy efficient solutions are sought at all network levels, especially at the medium access level. The IEEE 802.11 MAC protocol is optimized for Ad hoc Wireless Networks, but cannot be adopted for WSNs because it has the idle listening problem, which is a major source of energy waste.

Show moreEnergy consumption is a critical design issue in Wireless Sensor Networks (WSNs), since sensor nodes are battery operated, and replacing or recharging the battery is usually infeasible. Energy efficient solutions are sought at all network levels, especially at the medium access level. The IEEE 802.11 MAC protocol is optimized for Ad hoc Wireless Networks, but cannot be adopted for WSNs because it has the idle listening problem, which is a major source of energy waste. Several Medium Access Control (MAC) protocols have been proposed for WSNs to save the transceiver energy by introducing periodic listen/sleep cycles, and thus overcome the idle listing problem. The periodic listen sleep cycles, however, will increase the network latency and require extra overhead to establish and maintain synchronization among nodes in the network. This dissertation introduces a new MAC protocol for WSNs based on the SMAC protocol to improve its latency performance without compromising its energy consumption. The original SMAC provides an efficient solution for the energy consumption problem due to idle listening, but it increases latency especially in low duty cycle applications. TMAC was proposed to further reduce the energy consumption in SMAC and introduced the Forward Request-To-Send (FRTS) packet to solve the early sleep problem observed in TMAC. Later, Adaptive SMAC was proposed to reduce the latency problem in SMAC by at least 50% at light traffic load. Our new protocol, FASMAC, combines the advantages of both adaptive listening and the usage of FRTS packet in TMAC to further reduce the latency of SMAC. In FASMAC, a packet can travel at least three hops away from its source node within one time cycle. This results in at least 67% reduction in latency at light traffic when compared with the original SMAC. We also propose an energy model for performance evaluation of WSNs protocols using the network simulator NS2. The current energy model of NS2 was designed to handle Ad hoc Wireless Networks where the low power consumption sleep mode was not an issue. However, this is not the case in WSNs. We show that NS2 energy model is not suitable to evaluate the performance of WSNs protocols because it does not account for the low power sleep mode. This dissertation proposes a solution to this deficiency and provides simulation results that match real experimental results performed on the actual sensor motes.
