Download or read book Coverage and Connectivity Aware Energy Charging Mechanism Using the Mobile Charger for WRSNs written by Yuanping Kan and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless rechargeable sensor networks (WRSNs) have become an important issue in recent years due to their important roles in many monitoring applications. The WRSNs usually consist of many small sensors powered by rechargeable batteries. Since the sensor is small, the capacity of its battery is limited. As a result, the lifetime of WRSNs is limited which obstructs the large-scale deployment of WRSNs. To prolong the lifetime of WRSNs, extensive efforts for energy recharging have been taken in recent years. Wireless energy transfer (WET) technology as a revolutionized energy supply technology provides an alternative solution to prolong the lifetime of the WRSNs. Wireless charging of sensors using a mobile charger (MC) has been widely discussed in recent years. In literature, a lot of recharging algorithms have been proposed to construct recharging paths and determine the stopping points for mobile chargers to recharge the sensors. Most studies treated all sensors as equally important and aimed to maximize the number of recharged sensors. However, different sensors have different contributions, especially for network connectivity and coverage. The sensor closer to the base station has a larger contribution to network connectivity since its failure can block more data transmissions. On the other hand, a sensor that has a small overlapped sensing coverage with others, has a larger contribution to network coverage, since few or no neighboring sensors can replace its sensing coverage if the energy is exhausted. This study proposes an energy recharging mechanism, called ERSQ, which partitions the monitoring region into several equal-sized grids and considers the important factors, including coverage contribution, network connectivity contribution, and the remaining energy, aiming to maximize surveillance quality for a given WRSNs. Performance studies reveal that the proposed ERSQ outperforms existing recharging mechanisms in terms of the coverage, the number of working sensors as well as the effectiveness index of working sensors. The above ERSQ does not consider the data quality of the recharging requested sensors. A sensor in a sparse region has a larger contribution to data quality because few or no neighboring sensors can execute the sensing operation instead of the sensor if it is energy exhaustion. This study proposes an energy recharging mechanism, called JDCC, which partitions the monitoring region into grids and considers the contribution of each grid in terms of network connectivity, data quality as well as path cost, aiming to maximize the surveillance quality. Performance studies reveal that the proposed JDCC outperforms existing recharging mechanisms in terms of the data quality, the number of working sensors as well as the effectiveness index of working sensors.

Download or read book Power aware Control Strategies in Wireless Sensor Networks written by Hassan Jaleel and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the trends towards decentralization, miniaturization, and longevity of deployment continue in many domains, power management has become increasingly important. In this work, we develop power-aware control strategies for wireless sensor networks to improve the lifetime of the network and to ensure that the desired performance is guaranteed. For the case of static networks (networks of agents with no mobility), we identify the problem of the effects of power variations on the performance of an individual sensing device and on the entire network. To address this problem in a randomly deployed sensor network comprising of sensing devices whose sensing range is a function of transmitted power, we propose power-aware controllers to compensate for the variations in available power and maintain desired performance. We also propose a novel energy-efficient sleep-scheduling scheme that is random in nature and allows limited coordination among neighboring sensors for making switching decisions. This scheme is based on the concept of a hard-core point process from stochastic geometry, in which neighboring points are allowed to interact with each other through some predefined interaction laws. For the case of mobile networks (networks of agents with mobility), we propose a solid framework for distributed power-aware mobility strategies that can achieve any desired global objective while minimizing total energy consumption. This goal is achieved by first exploring fundamental trade-offs among various modes of operations of mobile devices and then exploiting these trade-offs for minimizing energy consumption. Through this framework, a whole class of decentralized power-aware controllers emerge for solving canonical problems in multi-agent systems like connectivity maintenance, rendezvous, and coverage control.

Download or read book Energy Recharging Using Mobile Charger for Improving Surveillance Quality in Wireless Sensor Networks written by Bhargavi Dande and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless sensor networks (WSNs) are used in many real-life applications in recent days. WSNs consists of tiny sensors with limited battery. Therefore, energy recharging to the sensors has been a promising issue and received much attention recently. With the help of wireless power transfer (WPT) technology, the mobile charger (MC) can transfer energy to the sensor nodes. This technology provides a new solution to prolong the lifetime of wireless rechargeable sensor networks (WRSNs). In literature, many recharging path construction algorithms have been proposed. Most of them considered that all sensors are equally important and designed algorithms to increase the number of recharged sensors or decrease the path length of the MC. However, different sensors have different coverage contributions. Recharging the sensors with a larger coverage contribution can achieve better surveillance quality. The proposed recharging scheduling algorithm is divided into three phases, including the Initialization, Recharging Scheduling and Path Construction Phases. In the second phase, this study proposed two recharging scheduling algorithms, namely the Cost-Effective (CE) algorithm and Cost-Effective with Considerations of Coverage and Fairness (C^2 F) algorithm. The proposed two algorithms construct paths for MC and select the recharging sensors based on the higher weight in terms of larger coverage contribution and smaller path cost. Performance results show that the CE and C^2 F algorithms yield better performance in terms of the fairness of recharging, recharging stability and coverage ratio, as compared with the existing studies. The above CE and C^2 F does not consider the spatial and temporal qualities of the recharging requested sensors. This study proposes a Recharge Scheduling Algorithm for Maximizing Spatial and Temporal Data Accuracy called RS-STQ, aiming to maximize the data accuracy of the given network. The proposed recharging schedule considers the spatial quality contribution of each recharging requested sensor. In addition, an energy management strategy is proposed for each requested sensor to locally adjust the sensing time sequence, aiming to improve the temporal quality. Each sensor might have a different energy consumption rate, therefore this study also formulates an adaptive recharging request threshold for the sensor nodes, which is suitable for real applications. The experimental study shows that the proposed algorithm outperforms the literature in terms of data accuracy as well as recharged sensor's spatial quality contributions. Since the RS-STQ is not suitable for the dense sensor networks, this study proposes a work-load aware recharge scheduling algorithm (WLARS) which aims to maximize the surveillance quality of the network by considering the spatial and temporal surveillance qualities of the recharging requested sensors and schedules the MC for recharging. The proposed WLARS firstly partitions the network into many sub-regions by considering the routing load of the sensors, aiming to evenly distribute the charging load of the MCs. Then each sensor determines its threshold value based on the queuing theory. In addition, the adaptive buffer of the MC and cooperation between the neighbouring MCs is also considered in this study. Performance results show that the WLARS outperforms the existing mechanism in terms of spatial and temporal surveillance qualities, average waiting time as well as uncharged sensors spatial quality loss.
