A wildland fire is an uncontrolled that occurs mainly in forest areas, although it can also invade urban or agricultural areas. Among the main causes of wildfires, human factors, either intentional accidental, are most usual ones. The number and impact fires expected to grow as a consequence global warming. In order fight against these disasters, necessary adopt comprehensive, multifaceted approach enables continuous situational awareness instant responsiveness. This paper describes...

The emergence and spread of Internet Things (IoT) technologies along with the edge computing paradigm has led to an increase in computational load on sensor end-devices. These devices are now expected provide high-level information instead just raw measurements. Therefore, processing tasks must share processor time communication tasks, both them may have strict timing constraints. In this work, we present empirical study, from perspective, process management carried out by IoT Operating...

Road traffic accidents are one of the main causes death and disability worldwide. Workers responsible for maintaining repairing roadways especially prone to suffer these events, given their exceptional exposure traffic. Since actuations usually coexist with regular traffic, an errant driver can easily intrude work area provoke a collision. Some authors have proposed mechanisms aimed at detecting breaches in zone perimeter alerting workers, which collectively called intrusion alarm systems....

The wireless Internet of Things (IoT) family grows without interruption. Every day more applications and devices are available to interconnect help solve multiple problems in areas such as health, critical infrastructure, industry, etc. Many the tasks be performed by IoT network require time synchronization for their correct operation, either use spectrum efficiently, add data from different sensors, or carry out coordinated communications. Each these has requirements regarding...

Cognitive wireless sensor network (CWSN) is a new paradigm, integrating cognitive features in traditional networks (WSNs) to mitigate important problems such as spectrum occupancy. Security an problem since these kinds of manage critical applications and data. The specific constraints WSN make the even more critical, effective solutions have not yet been implemented. Primary user emulation (PUE) attack most studied deriving from features. This work discusses approach, based on anomaly...

Wireless sensor networks (WSNs) have long been established as a suitable technology for gathering and processing information from the environment. However, recent applications new multimedia sensors increased demand more adequate management of their quality service (QoS). The constraints demands this QoS greatly depend on each individual network’s purpose or application. Low-Energy Adaptive Clustering Hierarchy (LEACH) is arguably most well-known routing protocol WSNs, but it not QoS-aware....

The increase in the number of mobile and Internet Things (IoT) devices, along with demands new applications services, represents an important challenge terms spectral coexistence. As a result, these devices are now expected to make efficient dynamic use spectrum, provide processed information instead simple raw sensor measurements. These communication processing requirements have direct implications on architecture systems. In this work, we present MIGOU, wireless experimental platform that...

Wireless body area networks (WBANs) present unique challenges due to their specific characteristics of mobility and over-the-body radio propagation. A huge amount factors—both internal external the network—affect WBAN channel conditions, so a reliable comprehensive theoretical model these communications is unfeasible impractical in real scenarios. Thus, an empirical performance analysis several channels presented this work, based on receiver signal strength indicator (RSSI) packet reception...

Cognitive Wireless Sensor Network (CWSN) is a new paradigm which integrates cognitive features in traditional Networks (WSNs) to mitigate important problems such as spectrum occupancy. Security an problem because these kinds of networks manage critical applications and data. Moreover, the specific constraints WSN make even more critical. However, effective solutions have not been implemented yet. Among attacks derived from features, one most studied Primary User Emulation (PUE) attack. This...

The growth of Device-to-Device (D2D) communications and the extensive use Wireless Sensor Networks (WSNs) bring new problems such as spectral coexistence spectrum saturation. Cognitive Radio (CR) appears a paradigm to solve these problems. introduction CR into WSNs solution utilization problem could be used not only increase reliability communications, but also optimize energy consumption. contribution this paper is cognitive lightweight strategy based on game theory collaboration proposed...

The loss of efficiency and dependability in wireless communications, caused by the increasing spectrum scarcity problem, is particularly critical for battery-powered devices such as sensor nodes. Cognitive Wireless Sensor Networks (CWSNs) arise order to mitigate this situation adding cognitive radio capabilities them. However, closed architecture limited resources traditional nodes represent a major constraint perform certain required tasks. On other hand, Software-Defined Radios (SDRs),...

With the fast expansion of Wireless Sensor Networks (WSNs) and increasing emergence new scenarios applications, extending their lifetime is crucial. Usually, WSN developers use generic algorithms deployment arrangements without considering specific needs network's application. Taking this application into account can result in a significant enhancement performance, both terms improving quality service (QoS). Furthermore, most do not consider final behavior network when nodes are nearly...
