Localization is a crucial requirement for mobile underwater systems. Real-time position information is needed for control and navigation of underwater vehicles, in early warning systems and for certain routing protocols. Past research has shown that the localization accuracy of networked underwater systems can be signiﬁcantly improved using collaborative tracking techniques. More speciﬁcally the Maximum Likelihood (ML) position estimates of a mobile collective can be computed from measurements of relative positions and motion, albeit centrally and non-real time. While for a number of underwater applications non-real-time position estimates may suﬃce, in this paper we focus on the design of a collaborative tracking solution that operates in real-time, yet is scalable and energy-eﬃcient. Using the ML solution as a baseline, we identify key factors that fundamentally limit the performance of real-time (centralized and distributed) solutions, quantifying their eﬀects via simulat...
