Optimization of Energy Consumption in Image Transmission in Wireless Sensor Networks (WSNs) using a Hybrid Method

In wireless sensor networks (WSNs)‎, ‎sensor nodes have limited resources with regard to computation‎, ‎storage‎, ‎communication bandwidth‎, ‎and the most important of all‎, ‎energy supply‎. ‎In addition‎, ‎in many applications of sensor networks‎, ‎we need to send images to a sink node‎. ‎Therefore‎, ‎we have to use methods for sending images in which the number and volume of packets are optim...

Maximal Utility Rate Allocation for Energy Harvesting Wireless Sensor Networks

There is currently tremendous interest in deploying energyharvesting wireless sensor networks. Engineering such systems requires striking a careful balance between sensing performance and energy management. Our work addresses this problem through the design and analysis of a harvestingaware utility-based sensing rate allocation algorithm. Based on a network utility formulation, we show that our...

LEBRP - A Lightweight and Energy Balancing Routing Protocol for Energy-Constrained Wireless Ad Hoc Networks

A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...

Energy Efficient Transmission in Wireless Sensor Networks

Aim of this study is analyzing energy conservation which is one of the most vital aspects in Wireless Sensor Networks (WSNs) for better network durability, since sensor nodes have limited resources of energy. In our propose technique, we have shown that how in presence of existing Error Control Coding (ECC) techniques and decoder complexity energy efficiency increased. That is by estimating tra...

OPTIMUM ENERGY ALLOCATION FOR DETECTION IN WIRELESS SENSOR NETWORKS Thesis

The problem of binary hypothesis testing in a wireless sensor network is studied in the presence of noisy channels and for non-identical sensors. We have designed a mathematically tractable fusion rule for which optimal energy allocation for individual sensors can be achieved. In this thesis we considered two methods for transmitting the sensor observations; binary modulation and M-ary modulati...
