The main goal in this paper is to obtain low power consumption of wireless sensor nodes and collected distributed data in environmental parameters monitoring. Communication module and the controller should be in idle state as long as possible when they are not active. In design and development of Wireless Sensor Networks (WSNs), one of the main challenges is to achieve long lasting battery lifetime...
Node localization is one of main support technologies for wireless sensor networks, and the location information of sensor nodes plays a key role in many application areas of wireless sensor networks. The positioning is the basis of tracking where target tracking is a fundamental application of wireless sensor network. The nature of target tracking is multi-node cooperation, and the core issue of...
Nowadays, wireless sensor networks attract researchers because of their popular applications in the military, communications, intelligence and medical aspects of vitality. Wireless networks can provide solutions to a lot of major problems in the world as they are low-cost, limited energy services, and there must be mechanisms to raise the efficiency of energy consumption to ensure a long lifetime...
With the advent of the Internet of Things, body-worn sensor nodes are continuously becoming more important. In case of bio-medical, rescue-worker or military applications sensitive data are often transmitted, requiring the need for encryption. The distribution of symmetric encryption keys is often an issue leading to security risks. Body-worn sensor nodes are generally employed in quickly varying...

Sensor nodes are deployed in remote wireless sensor networks (WSNs) which are mainly constricted by battery life and communication range. Single path routing mechanisms in WSNs leads to drastic power utilization and path failure. A multipath routing scheme using cooperative neighboring node concept is presented in this paper. Based on the availability of the energy at the neighboring nodes, multipath...
Wireless Sensor Networks (WSNs) is collection of large number of sensor nodes which are of limited capabilities, to collect sensitive information. With the advancement of this technology, one of the major concerns these days is of security. There are so many attacks possible on WSN, in Distributed-Denial of Service (DDOS) attacks, malicious nodes adapts many attacks such as flooding attack, black...
A large number of wireless sensor nodes (SNs) are usually deployed in a remote area, where these nodes accurately monitor the environment and communicate the data collected by the SNs, to a central processing station wirelessly. Since the SNs are powered by batteries, therefore, to prolong the network operating life, they must utilize energy efficiently. In this paper, we propose a method to control...
To perform some operation there is a need of some amount of energy over the node is same to the sending the single bit of data in the network. Data transportation reduces the network lifetime when sending data in sensor network. So the need to reduce the energy consumption for improving the network lifetime. As cluster head is aggregator node of the cluster it can take part in communication many times...
In this work a new method is proposed to obtain the deployment of sensor nodes with a maximum coverage area using a minimum number of sensor nodes in three-dimensional surfaces. The deployment is performed using the dual Delaunay triangulation/Voronoi Diagram. The position selection process considered the vertices as candidate positions and the sensing radius. The positions were selected based on...

Wireless sensor network is built by deploying sensor nodes in the environment. Sensors perform the monitoring task substituting human presence at the site. Sensor nodes are freely deployed in the real time environment. Sensor nodes work on in-built batteries because it's not possible to provide power in the real time scenarios. Sensor nodes are freely deployed in the network without any supervision...
Widely used computer systems have always become a target for different type of attacks. With the specifications of easiness in deploying and setting up low cost and low power consumption systems, Wireless Sensor Networks (WSN) have also become a specific target for attackers. The WSNs, which consist of sensor nodes that sends information they perceive and forward to a base station/sink, cannot be...
The application of vibration and acoustic wireless sensor networks (WSN) for intrusion detection has been proposed previously. In such networks, signals produced due to natural disturbances, like wind induced vibration or noise, can lead to excessive computation and data transaction leading to drainage of the power source due to power hungry RF data transmission. Such unwanted bursts of data transaction...
