From single-to multihop: The status of wireless localization

The solutions reviewed in this article, which have been proposed to solve the problem of providing reliable localization coordinate estimates in both single and multihop wireless network environments, are regarded as some of the most prominent ones. Although all these proposed solutions are addressing localization needs in different physical environments with exclusively single-hop or additionally multihop connectivity to reference nodes and have been either hardware implemented or just computer simulated, an attempt to summarize their characteristics in a somewhat comparative fashion is also shown.
