In the recent years, the technology of wireless sensor networks has gained a lot of importance. Wireless sensor networks are a special case of ad-hoc wireless networks. A wireless sensor network is a collection of sensor nodes that communicate through wireless links to work together to carry out functions. The sensor nodes’ basic function is to monitor the physical and environmental changes in ...

It is necessary for some of the applications of wireless sensor networks (WSNs) to estimate the geographical position of nodes. For the localization of wireless sensor nodes in wireless sensor networks, we took advantage of the learning machine approach based on binary support vector machine (SVM). During offline learning process, the received signal strength from reference nodes was chosen as ...

Determining the physical location of sensor nodes is the most basic requirement in most Wireless Sensor Networks (WSN) application. Wireless sensor network nodes’ self-localization techniques are discussed and studied in this paper. At first, the organization structure of wireless sensor network, the classify of node location algorithmic and node location computing method are introduced, the si...

This paper deals with a novel forwarding scheme for wireless sensor networks aimed at combining low computational complexity and high performance in terms of energy efficiency and reliability. This paper analyses the disadvantages of excessive clustering time because of the possible uneven cluster density. As a result, we present an ASMC algorithm. The proposed algorithm provides adaptability t...

Wireless Sensor Networks Due to its potential applications in various situations such as battle eld, emergency relief, environment monitoring, and so on, wireless sensor networks [50, 75, 118, 130] have recently emerged as a premier research topic. Sensor networks consist of a set of sensor nodes which are spread over a geographical area. These nodes are able to perform processing as well as se...

Wireless Sensor Networks(WSN) are becoming pop­ ular in a wide variety of applications. In a WSN, sensor nodes can be static or mobile, depending on applications. Handling mobility in a sensor network can pose interesting challenges in sensor protocol design, and special algorithms are needed to adapt to mobility in the network. In this article, we survey the current state of art in handling mo...
