3D 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...

Mobile Anchor-Based Localization Using PSO and Path Planning Algorithm In Wireless Sensor Networks

Anchor 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...

Path planning using a mobile anchor node based on trilateration in wireless sensor networks

In wireless sensor networks (WSNs), many applications require sensor nodes to obtain their locations. Now, the main idea in most existing localization algorithms has been that a mobile anchor node (e.g., global positioning system-equipped nodes) broadcasts its coordinates to help other unknown nodes to localize themselves while moving according to a specified trajectory. This method not only re...

Mobile-Assisted Anchor Outlier Detection for Localization in Wireless Sensor Networks

Accurate location information is critical to many applications in wireless sensor networks (WSNs) such as target tracking, environmental monitoring and geographical routing. Localization aims to figure out the locations of unknown nodes based on global locations of anchors and inter-node distance measurements. However, the existence of outlier anchors and outlier distances degrade localization ...
