Robust Localization System Using Vector Combination in Wireless Sensor Networks

Abstract: This paper proposes a vector-based localization system that uses both distance and angle information. In wireless sensor networks, the positions of nodes are commonly determined by a rangebased localization system using distance information. If both distance and angle information are available, it is possible to improve the accuracy of estimating the positions of nodes compared to a positioning system with only distance information. Existing studies using distance and angle information assume that all the node… Show more

“…If all nodes have a routing path to each other, the coordinate transformation of all AOAs can be conducted using mathematical techniques [21]. After the coordinate transformation of all AOAs, the vectors between all nodes can be recalculated in a single global coordinate system, thereby facilitating the estimation of the position of all nodes [9]. The method of recalculating vectors in this process is briefly introduced below.…”

“…The previously discussed conventional vector-based localization method [9] lacks the ability to ensure precise positioning accuracy in large networks. This limitation arises from the direct conversion of vector information into location data, disregarding the reliability of the information, which consequently results in cumulative errors during the vector synthesis process.…”
