Wireless sensor network contain hundreds of sensor nodes. These sensor nodes uses radio signal using communication. A wireless sensor node is well found with radio transceiver, sensor device and power component. A wireless sensor network is made up of sensor, embedded techniques, distributed information mechanism. Wireless sensor network is much versatile as compared to traditional wireless net...

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...

Clustering is an effective approach for managing nodes in Wireless Sensor Network (WSN). A new method of clustering mechanism with using Binary Gravitational Search Algorithm (BGSA) in WSN, is proposed in this paper to improve the energy consumption of the sensor nodes. Reducing the energy consumption of sensors in WSNs is the objective of this paper that is through selecting the sub optimum se...

This paper presents a review on energy efficient clustering protocols for heterogeneous wireless sensor network. Energy consumption is the critical design issue in the wireless sensor network since each node has a battery and each battery has limited lifetime. Therefore using the battery in efficient way became an important task for prolonging the lifetime and stability of the wireless sensor n...

Network security is vital for securing all information that passed through network computer; hence network security is the most important element in information security. Security is one of the critical concern occurred in WSN due to limitations in computing and fixed resource. Wireless sensor network have a broad area of invaluable games, defence, civil, household, entertainment application. W...

Abstract- Communication has become inevitably part of our day to day activities, in academic, business, banking, and other sectors. It has therefore become so important to implement good and efficient communication system. A reference point according to this research is the wireless sensor networking (WSN) system, and most important thing in communication is to be free from interference, attenu...

This paper proposes an efficient network architecture to improve energy consumption in Wireless Sensor Networks (WSN). The proposed architecture uses a mobile data collector to a partitioned network. The mobile data collector moves to center of each logical partition after each decision period. The mobile data collector must declare its new location by packet broadcasting to all sensor node...
