“…Whereas, the measured values of LoRa currents and the various timings involved are given in Table 1 and Table 2 respectively. E T otal = 11 * t 1 +11.02 * t 2 +22 * t 3 +(11 + I LORA ) * t 4 +3 * 10 − 3 * t 5 (1) Substituting the values from Table1 and Table 2 in equation ( 1 Battery life as given in equation ( 3) is plotted for the N-hour cycle and depicted in Figure 7 below. It may be noted that the battery life depends on transmitter power and is more than 30 years for a transmitter power of 15 dBm or less.…”

“…The end node consists of an ultra-low-power microcontroller, sensor system, LoRa modem, and actuators as shown in Figure 2. In the embedded system design the interfacing protocols at the physical layer play an essential role and it must allow the transparent connection to the network of additional devices [1]. A bus system is a communication path required for transmitting and receiving information between two or more devices.…”

Wireless sensor network (WSN) architectures involve multiple sensor nodes that cover large areas. It is difficult to deploy such nodes efficiently. However, based on clustering and collaboration, WSNs can organize efficiently and prolong system lifetime. In this paper, we discuss the design and implementation of a collaborative LoRa WAN using ultra-low-energy hardware and smart utilization of battery power. We have chosen the robust LoRa modulation technique and clustering method to design the end nodes. The sensor data from each of the end nodes are transmitted using low-power, long distance, and noise-resilient LoRa radio channels to their corresponding Cluster Heads(CHs), where it is first stored and then processed before transmitting further to the Gateways. The storing and then transmitting technique reduces the bandwidth requirement significantly. Also, the stored sensor data can be analyzed for system optimization. Immediately after transmission, the microcontroller goes to hibernation mode, whereas, the sensor system and the LoRa module are powered off until the next cycle. In this way, the power consumption by the end node is kept at its minimum and the battery life is extended to 35 years. Several challenges related to hardware design and network parameters optimization to achieve energy-efficient IoT-based LoRa WAN are presented and discussed.

Home automation systems are widely offered and increasingly available. The number of people who would like to purchase a property with intelligent solutions or equip their own home with such solutions is increasing. The devices and solutions of the home automation systems being built are most often based on IEEE 802.11g Wi-Fi communication, whose operation depends on the level of the wireless signal and is characterised by high latency. The use of communication based on the Inter-Integrated Circuit (I 2 C) protocol in the control of home appliances significantly reduces the cost of building the system. The aim of this paper is to analyse, compare and identify the most optimal solution for home automation based on I 2 C transmission. The analysis covers commercially available systems for simply and cheaply increasing I 2 C transmission for the smart home.
