Wireless communication technologies have the potential to significantly reduce cabling cost, cut down on weight, and simplify the overall structure of industrial embedded systems. Potential risks and costs of a technological switch from wired interconnections toward a wireless solution are difficult to estimate, however. Model-based system engineering can help to reduce risk and cost and to increase...
Workflows offer a great potential for enacting co-related jobs in an automated manner. This is especially desirable when workflows are large or there is a desire to run a workflow multiple times. Much research has been conducted in reducing the make span of running workflows and maximising the utilisation of the resources they run on, with some existing research investigates how to reduce the energy...
As the demand for large-scale wireless multimedia sensor networks increases, so does the need for well-designed protocols that optimize the utilization of available networks resources. This requires experimental testing for realistic performance evaluation and design tuning. However, experimental testing of large-scale wireless networks using hardware testbeds is usually very hard to perform due to...
This paper presents a simulation prototype design for wireless sensor networks (WSNs). It allows the performance evaluation (e.g., packet delivery rate, transmission latency and energy consumption) at high level, but with elaborate models of the hardware and software of sensor nodes. Many hardware components are modeled and the IEEE 802.15.4 standard is implemented. The prototype uses a clock based...
Energy efficiency is a primary concern in Wireless Sensor Networks because in general, wireless sensor nodes run on non-rechargeable batteries. Therefore, the estimating a expected node lifetime is indispensable. Thus, energy is an important issue that should be optimized by the application developer. However, in order for the developer to realize that the program may not be developed in accordance...
This paper presents IDEA1, a validated SystemC-based simulator for WSNs. It allows the system-level performance evaluation (e.g., packet transmission and energy consumption) with elaborate models of sensor nodes. IDEA1 uses a clock-based synchronization mechanism to support simulations with cycle accurate communication and approximate time computation. Its accuracy has been validated by a testbed...
In the recent years, Wireless Body Sensor Networks (WBSNs) attracted much attention in the research community. The key to success for WBSNs is the utilization of highly efficient transceivers and the application of intelligent policies to handle the limited (energy) resources. Simulations are a frequently used tool to evaluate different policies and analyze the performance of wireless networks in...
