Path Planning Algorithm for Mobile Anchor- Based Localization in Mobile Networks

چکیده
Mobile technology has helped to simplify networking by enabling multiple computer users to simultaneously share resources in a home or business without additional or intrusive wiring. A Mobile Network consists of hundreds or thousands of nodes and a small number of data collection devices. Localization of these mobile nodes is an essential issue in mobile networks because many applications require the mobile to know their locations with a high degree of precision. Various localization methods based on mobile anchor nodes have been proposed for assisting the mobile nodes to determine their locations. However, none of these methods attempt to optimize the trajectory of the mobile anchor node. Accordingly, proposed path planning scheme, ensures that the trajectory of the mobile anchor node minimizes the localization error and guarantees that all of the mobile node can determine their locations.

متن کاملPath 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...
