A trade-off between energy efficiency and optimized routing is massively recommended for transmission enhancement in wireless sensor networks (WSNs). Therefore, this paper, graph-based dynamic (GEODR) mechanism introduced to set up a balance consumption minimization throughput using WSNs. clustering scheme employed based on graph theory, cluster boundaries are formed distance vectors. Cluster h...

Energy efficiency operations are essential in increasing the lifetime of Wireless Sensor Networks. Clustering sensor nodes is an energy saving based interesting technique for achieving these goals. The main challenge in wireless sensor network is to optimize energy consumption when collecting data from sensor nodes. Efficiently collecting the data in wireless sensor networks plays a key role in...

Location information plays an important role in most of the applications Wireless Sensor Network (WSN). Recently, many localization techniques have been proposed, while these deals with two Dimensional applications. Whereas, Three task is complex and there are large variations altitude levels. In 3D environments, sensors placed mountains for tracking deployed air monitoring pollution level. For...

We describe an approach to the analysis of protocols for wireless sensor networks in scenarios with mobile nodes and dynamic link quality. The approach is based on the theorem proving system PVS and can be used for formal specification, automated simulation and verification of the behaviour of the protocol. In order to demonstrate the applicability of the approach, we analyse the reverse path f...

This chapter presents a real application of fuzzy logic applied to decision making in Wireless Sensor Networks (WSNs). These networks are composed by a large number of sensor devices that communicate with each other via wireless channel, with limitations of energy and computing capabilities. The efficient and robust realization of such large, highly dynamic and complex networking environments i...
