In this paper, a two-layer optimized railway monitoring system using Wi-Fi and ZigBee interfaced wireless sensor network (WSN) has been proposed for optimized bandwidth and power requirements. In the proposed network, a two-layer structure, i.e., wireless local area network (WLAN) and wireless personal area network (WPAN) of WSN is implemented and analyzed. The two-layer structure is implemented to...
Researchers throughout the years have been searching for methods to improve the available technologies to ease the users worldwide. In medical industries, researchers have made many improvements and development in medical equipment's to ease the medical professionals in serving patients. This work is the continuation of the previous research work in providing complete set of data for analysis on human...
The hierarchical routing protocol for wireless sensor networks is recognized as a technique that can reduce energy consumption of the networks and thereby increase their efficiency. Cluster head selection and network power management play important roles to improve the performance of this protocol. In this paper, a routing protocol for a small-scale wireless sensor network has been physically developed...
