This paper presents an optimal design of dynamic wireless automatic charging system for roadway-powered electric vehicles (RPEVs), which can effectively improve the charging performance of wireless electric vehicles. For automatic charging, the optimization of industrial automation systems on the application of RPEVs can fundamentally solve a series of problems, especially for the central issue of...
This paper presents the quantitative analysis for the optimal design of wireless power transmission (WPT) systems based on magnetic resonant coupling (MRC) mechanism. In this paper, the exemplified MRC-based WPT system adopts the series–series topology and one resonant coil, which shows that the energy efficiency and transferred power are both significantly affected by the mutual inductance of the...
We propose a new routing algorithm for wireless sensor networks for post-disaster road monitoring in this paper in which the wireless sensor nodes are arranged in a linear manner. It thus becomes necessary for the design of more efficient routing algorithms for such types of applications. Our new algorithm includes route establishment, packet forwarding and route maintenance by considering the special...
Water-regime monitoring system is a wireless-sensor-network (WSN) based real-time system. It often collects, transmits, analyzes and processes water regime parameters in large areas. Since the cluster-head selection mechanism affects directly on the energy consumption and network lifetime, both the cluster selection mechanism and the energy saving strategy play an important role on the design of network...
The expectations for sensor networks are growing. The performance of wireless sensor networks (WSNs) is greatly influenced by their network topology. In this paper, we consider the four patterned topologies that best supports connectivity among these deployed sensor nodes in two-tiered WSNs. The theoretical and simulation results are shown that the triangle-based topology has smaller cell number,...
Estimating the reliability and lifetime distribution of wireless sensor network is very useful in various applications. This problem is known to be NP-hard. In this paper, we present a hexagon tessellation sensor network model with role assignment scheme and estimate the reliability and lifetime distribution by employing a new improved Monte Carlo scheme which incorporates both simulation and analytic...
