In wireless sensor-actor networks, sensors probe their surroundings and forward data to actor nodes. Actors collaboratively respond achieve predefined application mission. Since actors have coordinate operation, it is necessary maintain a strongly connected network topology at all times. Moreover, the length of inter-actor communication paths may be constrained meet latency requirements. However, failure an cause partition into disjoint blocks would, thus, violate such connectivity goal. One...

The pipeline leakage problem is a very challenging and critical issue. Solving this will save the nation lot of money, resources more importantly, it environment. This paper discusses state-of-the-art leak detection systems (LDSs) data fusion approaches that are applicable to monitoring. A comparison LDSs performed based on well-defined criteria. We have classified critically reviewed these techniques. thorough analysis all recent works been provided.

Wireless sensor networks (WSNs) have proven to be an effective and dynamic paradigm for many applications, including structural health monitoring tracking systems. However, the supply of energy sensors plays a key role in success these applications as well design deployment networks. Currently, most WSNs are powered by batteries, which must replaced frequently, increasing maintenance costs operational complexity. In this paper, we propose practical framework, called wirelessly energy-charged...

Demand-side management (DSM) plays a key role in the future of smart grids. Recently, DSM researchers have developed various mathematical models to optimize demand response. Most these works ignore channel impairments' impact on optimization process. In this paper, we propose new noncooperative game theoretic model for grid's considering packet error rate our formulation. We set Nash equilibrium conditions proposed model.

Cyber Physical Systems (CPS) such as power plants, water desalination utilities are just a few examples of systems that may come under stealth attacks. These attacks can threaten the proper operations without any indication. This problem necessitates design control system is able to work In this paper, an improved observer-based stabilising controller proposed for CPS including random measurements and actuation delays it coming distributed denial service (DDoS) deception The occurrences DDoS...

In various practical scenarios, autonomous vehicles must navigate through unfamiliar areas to reach their destinations. This navigation is facilitated by two-dimensional (2D) and three-dimensional (3D) maps. Simultaneous Localization Mapping (SLAM) systems enable map surroundings while in motion. Traditionally, SLAM rely on physical sensors like LiDAR measure distances. However, these are costly consume significant power, particularly when used with drones. Consequently, the use of monocular...

In Wireless Sensor-Actor Networks (WSANs), actors collect sensor readings and respond collaboratively to achieve an application mission. Since coordinate their operation, a strongly connected network topology would be required at all time. addition, the path between may have capped in order meet latency constraints. However, failure of actor cause partition into disjoint blocks thus violate such connectivity goal. One effective recovery methodologies is autonomously reposition subset nodes...

Trust-aware routing in wireless sensor networks (WSNs) is a crucial problem that has drawn the attention of researchers. The motivation for tackling this arises directly from highly constrained nature WSN and its easy exposure to insecure conditions. In regard, reputation-based solutions are used provide trust-aware routing. However, approach requires node needs continuously monitor environment detect misbehaviour events. This considered be costly operation nodes because resource scarcity....

In most applications of Wireless sensor and actor network it is important to sustain connectivity among all actors at times. When an fails the inter-actor topology may get partitions into disjoint blocks application be negatively impacted. Tolerating failure restoring lost need performed while imposing least overhead on individual actors. this paper a Least Distance Movement Recovery (LDMR) algorithm proposed. LDMR distributed approach that exploits non cut-vertices in recovery process. The...

Wireless sensor and actor networks (WSANs) usually operate in harsh environment thus become susceptible to breakage connectivity due the failure of one or multiple nodes. The positions some these actors are critical sustainability inter-node communications. Specifically, node failures may cause network partition into disjoint segments. Given that WSANS deployed remote areas, restoring through self reconfiguring topology becomes most preferred solution. This paper investigates optimal...

This article focuses on cyber-physical systems involving a set of robots and sensors that are interconnected through wireless links. In applications operate in harsh environments, robot networks (WSRNs) may suffer simultaneous failures, which lead to partitioning the WSRN into unconnected subnetworks. The loss connectivity often leads degrade performance inability fulfill application mission. To address this issue, several proposals have been made literature where node mobility is exploited...
