In Wireless Sensor Networks (WSNs), the efficient use of sensor energy is a crucial point to extend the network lifetime and has been the focus of many industrial and academic researchers, since it is not a trivial task. Several methodologies for clustering, routing and energy saving in WSNs are available in the literature. However, the lack of detailed and crucial information from the analyzed studies...
Efficient power use is the fundamental to think about tried and true operation of wireless or remote sensor frameworks. This applies correspondingly to direct or linear sensor masterminds as they create when sensors are sent along linear frameworks such as pipelines. In this work, a innovative approach to manage imperativeness capable controlling to a dual base station or control center in a straight...
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...
The study and monitoring of wildlife has always been a subject of great interest. Studying the behavior of wild animals is a difficult task due to the difficulties of tracking and classifying their actions. Nowadays, technology allows designing low-cost systems that make these tasks easier to carry out, and some of these systems produce good results; however, none of them obtains a high-accuracy classification...
The research contribution presents data reporting using the adaptive dynamic pruning and data aggregation algorithms for query based wireless sensor network called as APDA. The aim of APDA is to reduce the network communication overheads through dynamic sub-network pruning to save the energy, minimize the unnecessary extra non relevant data transmissions. We construct tree rooted at base station BS...
Development of new type of multi-model sensor technology shows the importance of Wireless Sensor Networks (WSNs) where multi features can be sensed by a single sensor. Wireless sensor networks are mainly characterized by their limited amount of energy and memory. Constructing a network with this kind of sensor will lead to additional challenges with energy and memory constraints of wireless sensor...

WSNs composed of battery-powered nodes that happen to be connected with the base station to help for several measures and also task. Since sensor nodes will...
Aiming at the defects of the existing technology for Pleurotus eryngii cultivation environment monitoring system in Ningxia Pengyang County, such as: transmission of the data is not stable, small monitoring range and the sensors cannot move conveniently, only the environmental data in a fixed position within each mushroom shed can be collected, need to lay a lot of cables between the collector and...
Wireless sensor network is energy constrain network. Lifetime of network is defined by life of first certain percentage of dying nodes. Load balancing is a method to make energy consumption of all nodes equal and this way all nodes will die together. By load balancing, lifetime of network does not depend only on life of weak node but depends on life all nodes in network which helpful to increase life...
This paper discusses the use of Wireless Sensor Networks (WSN) for low data rate and power constrained applications like precision agriculture. Studies of different WSN technologies were conducted and their utility in precision agriculture was evaluated. A ZigBee based sensor node was implemented and field tested. The Sensor Network was also simulated in network simulator (NS2.34) and various network...
Wireless sensor networks (WSN) are extensively utilized in many important applications. It is very important that the data from wireless sensor nodes must successfully reach the main location apart from issues related to capacity, coverage and event of failure. In this paper we propose a failsafe wireless sensor network based on the burgeoning concept called cooperative communication. Here the sensor...
Indoor air quality (IAQ) is a term that describes the air quality of the building occupants. IAQ can be influenced by physical factors like dust particles, chemical or gaseous pollutants (including carbon dioxide, carbon monoxide and volatile organic compounds) and biological factors like molds and bacteria growth which largely depend on temperature and humidity condition of a room. These kinds of...
Wireless sensor networks are widely used in our daily life. It consists of various sensors which collect different information containing the identity, status, and location of an object or any other business, social or privately relevant information. But we pay attention to some issues related to sensor's location privacy. In this paper, we focus on protecting the sensor's location by introducing...
