Localization of Sensor Nodes using Mobile Anchor Nodes
Wireless Sensor Networks (WSNs) consist of spatially distributed wireless sensor nodes. Each sensor node cooperate with each other to monitor and collect data pertaining to physical or environmental conditions such as temperature, pressure, motion, sound, and other phenomena. Localization is an essential issue in wireless sensor networks because many applications require the sensor nodes to kno...
متن کاملMobile Anchor-Free Localization for Wireless Sensor Networks
Localization is a fundamental problem in wireless sensor networks. In this paper, we consider how to localize individual nodes in a wireless sensor network when some subset of the network nodes can be in motion at any given time. For situations in which it is not practical or costefficient to use GPS or anchor nodes, this paper proposes an Anchor-Free (AF) Mobile Geographic Distributed Localiza...
متن کامل3D Path Planning Algorithm for Mobile Anchor-Assisted Positioning in Wireless Sensor Networks
Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...
متن کاملHybrid Localization Algorithm of Mobile Nodes in Wireless Sensor Networks
—To improve algorithm compatibility and reduce localization errors and node energy consumption, a hybrid localization algorithm of mobile nodes in wireless sensor networks (HLA) is proposed. In HLA, each mobile node analyzes the locations and number of adjacent stationary nodes. When a mobile node has detected that more than two adjacent stationary nodes exist, it will use energy localization ...
متن کاملLocalization of Wireless Sensor Networks Using a Single Anchor Node
Localization of nodes in a sensor network is essential for the following two reasons: (i) to know the location of a node reporting the occurrence of an event, and (ii) to initiate a prompt action whenever necessary. Different localization techniques have been proposed in the literature. Most of these techniques use three location aware nodes for localization of an unknown node. Moreover, the lo...
