Cooperative Relative Positioning for Wireless Sensor Networks
نویسندگان
چکیده
In this paper, we present a completely distributed relative positioning algorithm for wireless sensor networks that does not require any external infrastructure support in the form of landmark nodes or manual initialization. Our algorithm uses measured inter-node distances and localizes the entire network in a local coordinate system upto a global translation, rotation and reflection. We benchmark our algorithm using TOSSIM simulations and show that it consumes only 0.1% of battery energy while exhibiting smaller localization errors. The main contribution of this work is a multi-phase approach that allows the resource constrained sensor nodes to collaborate with each other and solve the positioning problem for the entire network.
