The Virtual MIMO scheme is a proven technique to reduce energy consumption in WSN but it cannot resolve the energy efficiency problem in WSN. In high node density WSN, sensor nodes transmitted correlated information to sink node that will decreases the energy efficiency of WSN. For enhancing the energy efficiency of WSN, we propose distributed source coding based on virtual MIMO. In DSC-MIMO, DSC...
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...
In this paper we have developed a system for web based environment monitoring using the WSN Technology. WSN sensor nodes transmit data to the cloud-based database via Web API request.

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...
Clustering algorithm incurs significantenergy consumption for clusters and its ClusterHeads (CH) in Wireless Sensor Network(WSN). WSN brings a new attention over a real-timeintelligent system with its limitations and gainedmore research challenges. In last few years, WSNcan be used and seen in many real time applicationslike disaster management, pollution monitoring, temperature monitoring, traffic...
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...
