GPS-Free Node Localization in Mobile Wireless Sensor Networks
Overview An important problem in mobile ad-hoc wireless sensor networks is the localization of individual nodes, i.e., each node's awareness of its position relative to the network. This paper introduces a variant of this problem (directional localization) where each node must be aware of both its position and orientation relative to the network. Using global positioning systems for localization in large scale sensor networks is not cost effective and may be impractical in enclosed spaces. To address these issues, this paper proposes an algorithm for directional node localization based on relative motion of neighboring nodes in an ad-hoc sensor network without an infrastructure of Global Positioning Systems (GPS), anchor points, or even mobile seeds with known locations.
