In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

Rockfalls and landslides are hazards triggered from geomorphological climatic factors other than human interaction. The economic social impacts not negligible, therefore the topic has become an important field in application of remote monitoring. Wireless sensor networks (WSNs) particularly suited for deployment such systems, thanks to different technologies topologies that evolving nowadays. A...

LoRa technology is widely used in the Internet of things network applications. It enables low-volume data transmission via small wireless devices. The principle networks (an LPWAN technology: Low Power Wide Area Network) to transmit by air from sensors with a short range, about over ten kilometers. These should not be powered electricity, and batteries power them. Hospital visits are inevitable...

The industrial Internet of Things (IoT) is aiming to interconnect humans, machines, materials, processes and services in a network. Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. Radio Frequency Identification (RFID) and sensor networks are both wireless technologies that provide limitless future po...

one of the main challenges in wireless sensor network is energy problem and life cycle of nodes in networks. several methods can be used for increasing life cycle of nodes. one of these methods is load balancing in nodes while transmitting data from source to destination. directed diffusion algorithm is one of declared methods in wireless sensor networks which is data-oriented algorithm. direct...

Energy constraint is the biggest challenge in wireless sensor networks because the power supply of each sensor node is a battery that is not rechargeable or replaceable due to the applications of these networks. One of the successful methods for saving energy in these networks is clustering. It has caused that cluster-based routing algorithms are successful routing algorithm for these networks....

The growth of the Internet Things (IoT) continues to be rapid, making it an essential part information technology. As a result, IoT devices must able handle data collection, machine-to-machine (M2M) communication, and preprocessing data, while also considering cost, processing power, energy consumption. This paper introduces system for device indoor localization that uses variations in strength...

In recent years, wireless sensor networks data is taken into consideration as an ideal source, in terms of speed, accuracy and cost, in order to study the Earth's surface. One of the most important challenges in this area, is the signaling network coverage and finding holes. In recent years, wireless sensor networks data is taken into consideration as an ideal source, in terms of speed, accurac...

Sensors have become ubiquitous in buildings but are rarely connected to a network, and their potential analyse the performance, use, interaction with building is not yet fully realised. In coming years, we expect sensors part of Internet Things (IoT) grow numbers form Dense Indoor Sensor Network (DISN) that allows for unprecedented analysis buildings. Multiple technologies vie leading this tran...
