In underwater sensor networks (UWSNs), information transmission is extremely challenging because of the underwater channel. Underwater acoustic channel suffers from long propagation delay and low bandwidth is inclined to packet losses. Hence, the design of an energy efficient communication system is challenging under the water. In this paper, we present an energy efficient clustered multi-hop routing...
Energy hole is regarded as one of the challenging issues in wireless sensor networks (WSNs). According to this problem, nodes that are closer to the sink lose their energy earlier than other nodes. Consequently, it leads to the early breakdown of the network. One approach for preventing this problem is to use mobile sink rather than one or more sinks with fixed positions. Also, using fuzzy logic and...
Due to the advances of wireless sensor networks, radiofrequency identification (RFID) and Web-based services, large volume of devices have been interconnected to the Internet of Things (IoT). In addition, the tremendous number of IoT services provided by service providers arises an urgent need to propose effective recommendation methods to discover suitable services to users. In this paper, we propose...
The recent enhancement of sensor devices, such as the Micro-Electro Mechanical Devices (MEMs) used for information collection and dissemination, has led to the emergence of the Internet of Things (IoT). This new paradigm overlaps with many research area such as the Wireless Sensor Networks (WSNs) where sensor nodes are deployed over an area to perform local computations based on information gathered...
One of the major concern of Wireless Sensor Networks (WSNs) is to minimize the energy consumption of the sensor nodes. In multi-hop clustering, sensor nodes closer to the Base Station (BS) deplete their energy faster as compared to far away nodes. Transmission of own data as well as other nodes data by the nearer nodes is the prime cause for this uneven energy consumption. Hence, the nodes closer...
One of the most well-known clustering methods for wireless sensor network is, no doubt, the so-called low energy adaptive clustering hierarchy (LEACH) because it is simple and easy to implement. Although LEACH tries to provide a fair selection mechanism by randomly selecting a number of sensors as the cluster-heads, it does not take into account the distribution of sensors, the main reason that LEACH...
Various clustering protocols for ad hoc networks have been proposed in order to optimise the networks energy efficiency. These protocols rely on the formation of highly dense clusters which resulted in a large variation of cluster size and thus suffers from a poor load balancing. This paper introduce a novel distributed clustering algorithm using fuzzy logic for the formation of uniform size clusters...
Performance parameters are pretty important as well as clustering and routing algorithm in order for conditioning network lifetime in Wireless Sensor Network (WSN). The parameters like number of nodes, network area and radius of node coverage affects network lifetime directly. In this study the radius of node coverage's effect on network lifetime was checked out on various number of nodes. In the...

Efficient power conservation is crucial concerns for sensor networks to operate in the hostile environment. Therefore...
In this paper, we purpose Energy Efficient logical Cubical layered Path Planning Algorithm (EECPPA) and Multiple Sink EECPPA (MSEECPPA) for acoustic 3D Under Water Sensor Networks (UWSNs). EECPPA and MSEECPPA algorithms are completely distributed and highly adoptive in their execution in logical divided 3D networks into multiple cubes. Proposed models are flexible during location variations of sensors...
Considerable efforts have been expended on the centralised administration of WSNs. However, only very small functions, such as processing, memory, battery unit, and communication ability, can be configured using WSN nodes due to the associated resource restrictions. Moreover, unbalanced cluster construction and unbalanced energy dissipation can reduce network lifespan by a large extent. Therefore,...
Consider the problem of energy loss caused by inefficient use of energy in Wireless Sensor Networks (WSN). A clustering energy-efficient transmission protocol for wireless sensor networks based on ant colony path optimization (CEETP-ACPO) is proposed. Firstly, use the distributed cluster computing energy-efficient routing scheme (DCCERS) to select cluster heads according to the center of gravity and...
This paper contributes to recent improvements in energy-efficient clustering algorithms for static and homogeneous wireless sensor networks. We propose a modified algorithm, called NREC, which considers information on the locally normalized residual energy of sensor nodes. This information is weighted with the probabilistic threshold used in standard algorithms for periodic election of cluster heads...
This paper presents a framework for constructing a hierarchical categorical clustering algorithm on horizontal and vertical partitioned dataset. It is assumed that data is distributed between two parties, such that for general benefits both are willing to detect the clusters on whole dataset, but for privacy concerns, they refuse to share the original datasets. To this end, we propose algorithms based...
In this paper, a method for attribute selection is used in a dispersed decision-making system with dynamically generated disjoint clusters. The system that is used has been proposed in the earlier studies of the author. The aim of the paper is to apply in this system, the method of attribute selection that is based on the rough set theory. Another objective is to compare the results obtained with...

Some of these properties are self-healing, self-configuring, self-optimization and self-protection which...
This paper studies the problem of using path constrained mobile sinks (MSs) to collect data in Wireless Sensor Networks (WSNs). Accounting the feature of nonuniform node distribution, the proposed protocol aims at balancing the energy consumption, including energy expenditure to transmit data packet and network overhead, to make the network operate as long as possible with all nodes alive. We propose...
The multi-tenancy aware discovery of configurable Cloud services is one of the most important and difficult issues, because of multiplicity and non-standardization of their description in the Cloud. In this paper, relying on a feature model based specification of configurable WSDL services, we develop a multi-tenancy aware approach for their discovery. Our approach empowers multiple tenants to discover...
