Event detection has become a ubiquitous application in the domain of wireless sensor networks. In any distributed event detection system, duplicate event data that can increase the likelihood of network congestion is a primary concern, and in-network data aggregation is a popular approach to alleviate this problem; similarly, duplicate data can be discarded. We propose a novel approach that utilises...
Because of the limited energies of sensors, efficient data gathering in wireless sensor network has been received a great deal of attention recently. To prolong the network lifetime, in this paper, we study the problem of scheduling a mobile sink to some specific nodes, termed anchor nodes in this paper, for data collection and reducing the energy consumption of data transmission. While considering...
5G and Internet of things (IOT) develop rapidly, but the major applications of IOT-wireless sensor networks(WSNs) have numerous data, resulting in serious transmission load. In order to reduce the number of transmitted packets, this paper focuses on data aggregation for WSNs and proposes a novel event-based data aggregation mechanism using both principle component analysis(PCA) and support vector...
The recent proliferation of increasingly capable mobile devices has given rise to mobile crowd sensing (MCS) systems that outsource the collection of sensory data to a crowd of participating workers that carry various mobile devices. Aware of the paramount importance of effectively incentivizing participation in such systems, the research community has proposed a wide variety of incentive mechanisms...
This article looks at some of the challenges related to the deployment of the Internet Of Things (IoT), specifically to ascertain that security becomes an integral part of the technology rather than a bolted-on wrapper of limited efficacy. IoT security (IoTSec) is needed at all ‘layers’ of the IoT environment and may be specific to the IoT ‘layer’ in question.
Battery durability is often the major constraint in low power wireless sensor networks. Hence in most low power scheduling methods, nodes switch between the active mode and sleep mode periodically. This paper proposes an energy efficient data transmission scheduling for each node in a multi-channel multi-hop, data aggregation network. The proposed method reduces the active energy by scheduling each...
The wireless sensor networks (WSNs) is one of the developing and rapidly increasing field in the modern world. Due to this challenging task is to develop multi-function, low cost and low-power sensors. In WSNs, large number of sensor nodes within the cluster sensed the environment and send data to the cluster head. This paper contain new energy efficient clustering algorithm which is used for effectively...
Crowdsensing recently attracts great attention from both industry and academia. By fusing and analyzing multi- dimensional sensing data collected from crowdsensing users, it is possible to support health caring, environment mentoring, traffic mentoring and social behavior mentoring. Nonetheless, how to preserve users' data privacy during data fusing, e.g., data aggregation, has been rarely discussed...
In spite of the pronounced benefit brought by crowdsensing, a user would not participate in sensing without adequate incentive, indicating that effective incentive design plays a critical role in making crowdsensing a reality. In this work, we examine the impact of two conflicting factors on incentives for users' participation: 1) the concern about privacy leakage and 2) the (positive) network effect...
With the rapid development of portable mobile devices, crowd sensing systems have been recognized as a key technology to utilize the data collected by the portable mobile devices towards scalable and flexible mobile services. However, since the information provided by devices may not be reliable, the aggregated results of the collected data may not be accurate. To tackle this challenge, various truth...
Applicability of Wireless Sensor Networks is found in fields manifold. Energy issues proved to be a continuous setback to the performance of these networks. Data aggregation and the use of local base stations is seen as a promising solution to the problem. Clustering is a simple technique to achieve this. The local base stations or the cluster heads aggregate data from nearby nodes, process it and...
Internet of Things (IoT) is a new paradigm which is enormously gaining ground in today's world. In order to maintain desirable service quality in the transmission of sensed data, data aggregation schemes are highly used. The main goal of data aggregation scheme is to collect and aggregate data packets in an efficient manner so as to reduce power consumption, traffic congestion, and to increase network...

The object of the invention is to propose a model which overcome the disadvantages of an earlier system that...
Wireless sensor networks commonly implemented in such areas like volcano, fire observing, remote sensing and in army etc. Communication cost as well as energy utilization is minimized by implementing strategy called as data aggregation in wireless sensor networks. At the time of data routing, partial outcomes are consolidated by the data aggregation method from lower layer nodes. Related work illustrates...
In smart Wireless Sensor Networks (WSNs), clustering is one of the most power efficient techniques which minimize the transmission ranges of sensor nodes. Instead of sending packets directly to the BS with high power levels, sensor nodes in the sensing filed can be organized in groups (i.e. clusters), where Cluster Heads (CHs) manage the transmission by aggregating the whole group of packets and retransmit...
The rapid production, huge increasing features and capabilities of mobile sensing devices such as smart phones increases usage of variety of mobile sensing application. As WSN is having huge coverage area, data is collected from multiple mobile users. For this huge amount of data, statistics needs to be periodically updated for applications such as population monitoring, temperature monitoring and...
The number of connected devices — also known as Internet of Things (IoT) — is exponentially increasing.

For efficiently gather the data sink's mobility pattern should be...
The Energy Star standard is useful for comparing dryer models but gives much less information about performance once installed in a residence. All energy efficiency (EE) efforts need to consider the impact on the drying process and the textiles being dried. The length and efficacy of the drying process is affected by the temperature and humidity of the dryer's environment.
Data aggregation is known as the collection of data from a set of sensors toward a sink node with routing algorithms. For that, many structured protocols used for aggregation and forwarding packets. Since, sensor nodes are less battery powered devices, its maximum energy spent for constructing certain topologies. There are number of prior works based on tree-based or cluster-based, grid based and...
