Energy Aware Node Selection for Cluster-based Data Accuracy Estimation in Wireless Sensor Networks

The main objective of this paper is to reduce the number of sensor nodes by estimating a trade off between data accuracy and energy consumption for selecting nodes in probabilistic approach in a distributed network. Design Procedure/Approach: Observed data are highly correlated among sensor nodes in the spatial domain due to deployment of high density of sensor nodes. These sensor nodes form no...

Optimal Node Selection using Estimated Data Accuracy Model in Wireless Sensor Networks

One of the major task of wireless sensor network is to sense accurate data from the physical environment. Hence in this paper, we develop an estimated data accuracy model for randomly deployed sensor nodes which can sense more accurate data from the physical environment. We compare our results with other information accuracy models and shows that our estimated data accuracy model performs bette...

Comparison of Sensor Node Scheduling Algorithms in Wireless Sensor Networks

The main advantage of wireless sensors networks (WSNs) is their ability to operate unattended in harsh environments in which contemporary humanin-the-loop monitoring schemes are risky, inefficient and sometimes infeasible. In some application scenarios, replenishment of energy resources might be impossible, and therefore sensor node lifetime shows a very strong dependency on battery lifetime. S...

Service-oriented Middleware for Wireless Sensor Networks

There is a wide range of applications for wireless sensor networks (WSNs) with different needs. The network infrastructure and data dissemination protocol change according to each specific application requirement. To achieve the best network performance, it is important to adapt the network operation to the application needs. We propose a middleware system for WSNs, which provides a layer betwe...

an efficient protocol for data aggregation in wireless sensor networks

sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...
