Design and Implementation on Patchouli Growth Environment Monitoring System Based on IoT

With the development of the times, the concept of "interconnection of all things" has been deeply rooted in the hearts of people. As an early and developing Internet technology, the Internet of things(IoT) has shown its infinite potential in many fields of social life. In agriculture, the agricultural IoT is coverring a growing number of fields: greenhouse planting, climate factor collection, climate prediction and so on. Based on this idea, the design idea of "patchouli growth environment monitoring system" is put forward. In this paper, the medicinal plant "patchouli" is studied, and its medicinal value and growth factors are discussed. Meanwhile, based on zigbee technology, we design a set of feasible monitoring scheme including hardware and software. The hardware part used ZigBee wireless network design, mainly relies on the cc2530 chip and the esp8266 wifi chip to carry on the wireless distance transmission to the sensor data. It interacts between OneNET cloud server and mysql database through MQTT protocol, TCP/IP protocol and HTTP protocol.

Optimal Energy-Delay Scheduling using Improved Beetle Antennae Search (BAS) for Energy-Harvesting WSNs

Optimal energy delay scheduling for capacity allocation issues on interference chan- nel energy harvesting wireless sensor networks (EH-WSN) addresses for static data streams and energy topography. To create the optimizations issue of unique and multi-time interval corre- spondingly. The goal is for reducing overall regression of the network. Though, the optimization issue is not convex, creating it hard to get an optimal solution. The main objective of this manuscript is directly addressing the original non-convex formulation using the enhanced Beetle Antennae Search (BAS) algorithm that efficiently finds the optimal solution. This algorithm is also better for another complex optimization issues on wireless network design. The simulations under delay, delratio, drop, energy, network lifetime, overhead and throughput are carried; the expected outcome displays that improved BAS algorithm executes considerably better than the convex approximation technique. This idea is useful for other complex optimization issues on wireless network design.

Implementación de una red IoT con GPRS para monitorear los parámetros en un vehículo en tiempo real

This Project seeks a new alternative to connect wireless networks with the Internet of Things (IoT), both for the collection of information, transmission and reception of data in real time, facilitating the visualization of them through a database and generating historical reports which contributes to the supervision of vehicles on the roads. When working with the acquired data, these are constantly updated since it usually tends to lose valuable information, therefore, it is necessary to consolidate connectivity through GSM in conjunction with GPRS technology to implement a prototype and explore the operation of LoRa. This prototype focuses on census the parameters of speed, temperature, water level and fuel level through virtual platforms that give evidence of the status of each sensor incorporated in the vehicle, therefore, this wireless network design seeks to find the drawbacks that are presented in a section of poor accessibility to cellular coverage.

Data Science in Vehicular Ad-Hoc Networks

Vehicular Ad-hoc Networks (VANET) is a mobile ad-hoc network in which vehicles move rapidly through the road and topology changes very frequently. VANET helps to provide safe, secure, and more comfort travel to travelers. Vehicles intelligence is an important component in high mobility networks, equipped with multiple advanced onboard sensors and contain large volumes of data. Datascience is an effective approach to artificial intelligence and provides a rich set of tools to exploit such data for the benefit of the networks. In this chapter, the distinctive characteristics of high mobility vehicular ad-hoc networks are identified and the use of datascience is addressing the resulting challenges. High mobility vehicular ad-hoc networks exhibit distinctive characteristics, which have posed significant challenges to wireless network design. Vehicle traffic data, and road traffic future condition data are analyzed and incorporated to enhance the VANET performance. VANETs technologies are useful to efficiently model and reliably transmit big data.

Optical Wireless Network Design for Off-Body-Sensor Based Monitoring

In this article, we propose an all-optical bidirectional wireless communication system for off-body sensor communication. Optical technology uses infrared (IR) for uplinks and visible light communication (VLC) for downlinks. From numerical simulations, we discuss the impact of body sensor positions on IR and VLC channels. Our goal is to evaluate the possibilities of using optical technology to transmit sensor data for extreme positions such as the ankle, for which the presence of the body creates blockages. In addition, we also consider the variations in orientation of transceivers due to random mobility of body parts during normal movement. Based on a statistical approach, we evaluate performance in terms of outage probability using channel impulse response sets corresponding to the studied scenario, which is health monitoring. Considering a given quality of service, we address trade-offs related to emitting power and data rate. We discuss the results regarding sensor node position and body reflectivity specifically for ankle sensors, corresponding to an extreme but realistic position in the health-monitoring context.

Design of Wireless Network System for Digital Village Using Wireless Distribution System

The purpose of this research is to create a wireless network design in Cijambe Village using WDS so that Cijambe Village can enjoy internet services through wireless networks, which can be used to find information, communication, and market products owned by village communities. A wireless network is one of the best alternatives in building a computer network that is practical and flexible and has high mobility. Most organizations use wireless networks to support existing cable networks, but in reality, the wireless network still uses Unshielded Twisted Pair (UTP) cable media as the backbone of Access Points (AP). Cijambe Village is a village located in Paseh District, Sumedang Regency. Cijambe village is divided into two hamlets, namely Cijambe Hamlet and Parugpug Hamlet. Cijambe village has an area of 357 hectares. The research method used in this study is a qualitative descriptive research method. The steps taken in this research are analysis and design. the conclusion is that wireless network design for digital villages using Wireless Distribution System (WDS) has a better degree of flexibility than the backbone that uses Unshielded Twisted Pair (UTP) cable. Radio wave signals from 19 AP units can reach the entire area of Cijambe Village which has an area of 357 hectares and is divided into 2 hamlets namely, Hamlet Cijambe and Parugpug Hamlet. The design made has thought of a standard level of security with routers and firewalls.

Practical Design of a WSN to Monitor the Crop and its Irrigation System

Due to environmental problems, such as the lack of water for irrigation, each day it becomes more necessary to control crops. Therefore, the use of precision agriculture becomes more evident. When it comes to making decisions on crops, it is evident the need to apply the concept of Smart Agriculture, that focuses on utilizing different sensors and actuators. As the number of IoT devices used in agriculture grows exponentially, it is necessary to design the implemented network so that the data is transmitted without problems. The present work shows a wireless network design, in which we use the information collected by the sensors of a Wireless Sensor Network (WSN), and a Wireless Mesh Network (WMN) formed by Access Points (AP) to transmit the data to a network that monitors agriculture for smart irrigation. In addition, through simulations we have presented a proposal of the maximum number of nodes that must be connected to an AP so that the network is efficient.
