Bluetooth has constantly evolved from its cradle in 1997 to the last 5.2 version 2020. With each update and amendment, it gained speed, range, versatility. One of latest introductions was Mesh Profile (BMP) making a technology suitable for wide variety applications. Nevertheless, BMP designed maintain compatibility with 4 devices already deployed market. This imposes some restrictions that plac...
Abstract. Bluetooth is a short-range radio link which originally was developed to eliminate cables between portable and/or fixed communicating devices. Bluetooth wireless technology is a de facto standard, as well as a specification for small-form factor, low-cost, short range radio links between mobile PCs, mobile phones and other portable devices. Today Bluetooth is a true ad-hoc wireless net...
When several Bluetooth networks interconnect through a number of bridge nodes, they form a scatternet. However, no routing protocol has yet been defined for Bluetooth scatternets. Meanwhile, because of its small size and low cost, Bluetooth is widely “pervasive”, in the sense that even low cost electrical appliances will be expected to become Bluetooth enabled. If so, scatternets consisting of ...
In past few years, automatic irrigation system has seen a rapid growth in terms of technology. At present cost-saving technology, labor-saving are the addressing key issues in irrigation. This paper gives a review of these systems based on existing technologies and also proposes an economical and generic automatic irrigation system based on wireless sensors with GSM-Bluetooth for irrigation sys...
Bluetooth is an important and increasingly popular wireless communication standard, and in recent years a large number of Bluetooth products have been introduced commercially. Its chief advantages are small and low power consumption, which make the technology an attractive choice when setting up short-range wireless ad hoc networks. A typical Bluetooth network, known as a piconet, consists of o...
The aim of this study is to assess the potential use of Bluetooth data for traffic monitoring of arterial road networks. Bluetooth data provides the direct measurement of travel time between pairs of scanners, and intensive research has been reported on this topic. Bluetooth data includes “Duration” data, which represents the time spent by Bluetooth devices to pass through the detection range o...
Even though home automation is a well-known research and development area, recent technological improvements in different areas such as context recognition, sensing, wireless communications or embedded systems have boosted wireless smart homes. This paper focuses on some of those areas related to home automation. The paper draws attention to wireless communications issues on embedded systems. S...
A Zigbee and Bluetooth converter is designed in this paper. A multi-sinks wireless sensor network is used to solve the notable problems appeared in the single node wireless sensor network. These problems are solved in converter system such as data transmission reliability and node energy consumption imbalance and so on. The converter system can be better adapted to the large-scale, high-density...
