Anchor-Free Localization Method for Mobile Targets in Coal Mine Wireless Sensor Networks
Severe natural conditions and complex terrain make it difficult to apply precise localization in underground mines. In this paper, an anchor-free localization method for mobile targets is proposed based on non-metric multi-dimensional scaling (Multi-dimensional Scaling: MDS) and rank sequence. Firstly, a coal mine wireless sensor network is constructed in underground mines based on the ZigBee t...
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 کاملAnchor Adaptive Path Planning Method Based on Cooperation for Localization in Mobile Wireless Sensor Networks
—Localization in Mobile Wireless Sensor Networks(MWSNs) has become a focus research in recent years, path planning algorithm makes great influence on localization performances. There are abundant existing path planning methods, but few of them can be applied in MWSNs. In order to avoid energy and resource waste caused by anchors traversing sparse area randomly, we first realized anchors move a...
متن کاملMobile anchor positioning for wireless sensor networks
Localisation is one of the most important issues in wireless sensor networks, because the location information is typically useful for coverage, deployment, routing, location service, target tracking and rescue operations in wireless sensor networks. The localisation protocols are classified into two categories: range-based protocol and range-free protocol. The range-based protocols employ dist...
