A wireless sensor network (WSNs) is a network that consists of a large number of ultra-small autonomous devices which are resource-constrained called sensor nodes. Sensor networks may be deployed for a wide range of ...

The objective of this thesis is to save the nodes energy using optimization approach with Particle Swarm Optimization Algorithm. The network area is divided to several regions for parametric study. In the proposed method, ...

In this thesis, the energy efficient and connectivity problem in wireless sensor networks (WSNs) is presented. There are more difference between energy levels of near nodes and far nodes of cluster heads. This problem ...

The aim of this thesis is to save the energy of the nodes. The first goal of this thesis is to reduce the total energy consumption of the wireless sensor network and the second is to increase the reliability of the protocol ...
