SSOLA:a Smart Space Oriented Fast Positioning Algorithm

This paper proposes a smart space oriented location awareness scheme(SSOLA)based on MDS(multidimensional scaling),which can position all the nodes of the networks accurately only by means of the connectivity information—who is within communications range of whom.Provided with known positions for several anchor nodes,we can get the absolute positions for all nodes.Through simulation studies,SSOLA is demonstrated that it is more robust to measurement error,and has less location error,less time cost and better scalability than previous proposals in the same conditions.Furthermore,it can achieve comparable results using much fewer anchor nodes than previous methods,and even yields relative coordinates when no anchor nodes are available.SSOLA can be used in large and heavy traffic wireless environment,such as intelligent battlefield,tactical internet,etc.
