A Survey of Localization Schemes in Wireless Sensor Networks with Mobile Beacon
Location information is critical essential and indispensable for many applications of wireless sensor networks. Anchor-based localization schemes are more precise than anchor-free ones, but the anchor nodes are more expensive than ordinary sensor nodes. Recently, there has been much focus on mobile-beacon based localization, for they can lower the cost the network while keeping the localization precision. This paper surveys the current state of the art for mobile-beacon based localization algorithms. We give the taxonomy of these schemes including range-base vs. Range-free, single beacon vs. Multi-beacons, omni-directional vs. Directional antenna. Moreover, we also give a review of path planning methods which are critical to localization algorithm with mobile beacon, and we classify them into static and realtime schemes. We briefly introduce the steps of each localization and path planning algorithm, which serves as an introduction and survey for researchers interested in the area * of localization of wireless sensor networks.
