IRELESS sensor networks (WSNs) are just one of the presently hot research topics. With the energy consumption, the new route may be reconstructed with energy sufficient nodes. An Operating System (OS) for sensor nodes should implement a low-power task-scheduling. As wireless sensor nodes are typically very small electronic devices, they can only be equipped with a limited power source of less than 0.5-2 ampere-hour and 1.2-3.7 volts.

The access points (also called sinks) coordinate sensor nodes. Therefore, an accurate energy model is required for the … energy path to the sink towards the minimum energy consumption, which cause an unbalanced distribution of residual toward all sensor node in network partitioned. Despite the open problems in WSNs, there are already a high number of applications available. A widely employed energy-saving technique is to place nodes in sleep mode, corresponding to low-power consumption as well as to reduce operational capabilities. Section V briefly. INTRODUCTION Energy consumption and energy modeling are important issues in designing and implementing of Wireless Sensor Networks (WSNs), which help the designers to optimize the energy consumption in WSN nodes. When those algorithms are developed and tested with some well-known network simulators like NS3, OPNET, the energy estimation aspect is not a key criterion, because these simulators have their own specific energy models. However to solve this quite difficult problem there is a need to take a holistic approach to the issue of energy management in sensor nodes and networks. Wireless sensor networks are aggregates of numerous small sensor nodes. sensors Article Energy Consumption Model for Sensor Nodes Based on LoRa and LoRaWAN Taoufik Bouguera 1,2,, Jean-François Diouris 1, Jean-Jacques Chaillout 2, Randa Jaouadi 3 and Guillaume Andrieux 1 ID 1 University of Bretagne Loire, Polytech Nantes, IETR, 44300 Nantes, France; jean-francois.diouris@univ-nantes.fr (J.-F.D.
