3D Path Planning Algorithm for Mobile Anchor-Assisted Positioning in Wireless Sensor Networks

Mobile 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...

A multiple criteria algorithm for planning the itinerary of mobile sink in wireless sensor networks

The mobile sink can increase the efficiency of wireless sensor networks. It moves in a monitored environment and collects the network nodes information. Thus, by the sink we can balance the power consumption and increases the network lifetime. Determining path of the sink's movement is usually modeled as an optimization problem where finding optimal solutions require collecting value of all the...

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...

A Mobile Anchor Assisted Localization Algorithm Based on Regular Hexagon in Wireless Sensor Networks

Localization is one of the key technologies in wireless sensor networks (WSNs), since it provides fundamental support for many location-aware protocols and applications. Constraints of cost and power consumption make it infeasible to equip each sensor node in the network with a global position system (GPS) unit, especially for large-scale WSNs. A promising method to localize unknown nodes is to...
