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...

Wireless sensor network is a novel network with embedded system technology, communication technology and sensor technology as a whole, it is one of the wireless network form that is very rapid development at present, wireless sensor network has the characteristics of flexibility, adaptability, stable performance, wide coverage etc, so it is widely used in environmental monitoring, community sec...

A network is designed to have maximum area coverage with less energy consumption. Energy and coverage both are the current issue of wireless sensor network. The performance of wireless sensor network is affected by these two issues. Several methods are developed to make a network efficient. In this paper PSO Algorithm has been reviewed to resolve the challenges and issues of wireless sensor net...

In the next generation wireless sensor networks system, various wireless technologies and wired networks in together, in order to meet the various needs of users. Our focus in this paper is to introduce a few design goals, different wireless/wired networks complement each other, thus help users to access the best network in accordance with the current business. Each network is different with ea...
