Wireless Data Transmission

Real-time monitoring systems and sensors are not complete without wireless data transmission modules. Improving energy efficiency requires examining various system parameters that affect the power consumption of transmitting and receiving devices. The most important parameter of any autonomous wireless network is its uptime. In this work, we used LoRa wireless modules on the SX1278 chip manufactured by Semtech to determine their power consumption in various operating modes. The obtained data were used to build a consumption model of the device when connected to a receiver. Three operating modes are considered: transmit mode, receive mode and sleep mode. In an ideal communication channel, all transmitted data reaches the receiver with 100% probability. In a real situation, data reaches the receiver with a certain probability, depending on the communication channel, transmission power, distance to the addressee, and network parameters. In this work, the occurrence of an error is random. In this case, the occurrence of an error during reception entails a lack of confirmation of receipt or a request for re-sending data. Sending data again increases the power consumption of the device and, consequently, decreases the operating time of the wireless device. This paper shows the dependences of the operating time on various initial monitored parameters of the device, such as: confirmation timeout, packet length, time of one transmission cycle and the maximum number of retransmissions in one cycle. The developed model for predicting the consumption of the device can be used in the design of autonomous wireless sensor monitoring networks.

Data security, privacy and authenticity are crucial in wireless data transmission. Low power consumption is the main requirement for any chip design targeting the Internet of Things (IoT) applications. In this research paper, a comparative study of eight authenticated encryption and decryption algorithms, selected from the “Competition for Authenticated Encryption: Security, Applicability and Robustness” (CAESAR), namely, ACORN, ASCON, CLOC, JOLTIK, MORUS, PRIMATEs, SCREAM and SILC, is presented. The FPGA and ASIC implementations of these eight algorithms are synthesized, placed and routed. Power, area, latency and throughput are measured for all algorithms. All results are analyzed to determine the most suitable algorithm for IoT applications. These results show that ACORN algorithm exhibits the lowest power consumption of the eight studied at the expense of lower throughput and higher latency. MORUS algorithm gives the highest throughput among the eight selected algorithms at the expense of large area utilization.

Abstract In this paper a prototype framework for simulation of wireless sensor network and its protocols are presented. The framework simulates operation of a sensor network with data transmission, which enables simultaneous development of the sensor network software, its hardware and the protocols for wireless data transmission. An advantage of using the framework is converging simulation with the real software. Instead of creating a model of the sensor network node, the same software is used in real sensor network nodes and in the simulation framework. Operation of the framework is illustrated with examples of simulations of selected transactions in the sensor network.

Wireless Sensor Network (WSN) is an emerging area in past few decades. Through the integration of low cost sensor nodes with Internet of Things (IoT), lots of applications are common now these days. Each application senses and transmits the fused data to the sink. This wireless data transmission is called routing and is the main governing factor for the span of the sensor network. This paper analyzes and presents different variety of routing techniques based on connectivity structure of the sensors. The type of application for which sensor nodes are used governs selection of a routing technique.

Fire Accidents

Disasters are happening due to drastic environmental destructions that may cause damage to wireless data transmission networks. There must be a system that monitors and takes necessary actions for reliable communication which can be provided by the wireless sensor network (WSN) that were organized as multiple nodes. In the heterogeneous environment these ubiquitous nodes are able to handle disasters like floods, drought, earthquake, and cyclone, or network fluctuations through fire accidents. Disasters can be monitored by augmenting a variety of sensors to sense and detect sudden changes in temperature, pressure, seismic wave, noises, etc. Large numbers of sensor nodes are distributed over a geographical area in WSN providing trustable data transfer with multi node sink. In this chapter, the authors review various WSN routing protocols for reliable data transfer in disaster management using multiple sink. The main objective of this chapter is to provide future research directions to enhance QoS in disaster management.

In agriculture, it becomes more and more important to have detailed data, e.g. about weather and soil quality, not only in large scale classic crop farming applications but also for urban agriculture. This paper proposes a modular wireless sensor node that can be used in a centralized data acquisition scenario. A centralized approach, in this case multiple sensor nodes and a single gateway or a set of gateways, can be easily installed even without local infrastructure as mains supply. The sensor node integrates a LoRaWAN radio module that allows long-range wireless data transmission and low-power battery operation for several months at reasonable module costs. The developed wireless sensor node is an open system with focus on easy adaption to new sensors and applications. The proposed system is evaluated in terms of transmission range, battery runtime and sensor data accuracy.
