Cooperative Localization Using Received Signal Strength and Least Squares Estimation Methods

Abstract

In this paper we use two Recursive Least Squares (RLS) estimation methods to solve the cooperative localization problem based on Wi-Fi received signal strength measurements between pairs of nodes in a network that can establish communication links. A link can be between an anchor node and a non-anchor node or between a pair of non-anchor nodes. It is the latter piece of information that makes cooperation possible and this problem different from multilateration. We evaluate the performance of Newton-Raphson and Gauss-Newton RLS methods and show that cooperation can offer significant gains in performance over multilateration, which does not use cooperation.
