Received signal strength (RSS)-based wireless localization is easy toimplement at low cost. In practice,exact positions of anchors may not beavailable. This paper focuses on determining the location of a source in thepresence of inaccurate positions of anchors based on RSS directly. We first useTaylor expansion and a min-max approach to get a maximum likelihood estimatorof the coordinates of the source. Then we propose a relaxed semi-definiteprogramming model to circumvent the non-convexity. We also propose a roundingalgorithm considering both inaccurate source location and inaccurate anchorlocations.Simulation results together with analysis are presented to validatethe proposed method.
