Comparing SOS and SDP relaxations of sensor network localization

Gouveia, João; Pong, Ting - In: Computational Optimization and Applications 52 (2012) 3, pp. 609-627

for the sensor network localization problem. In particular, we show that Biswas and Ye’s SDP relaxation is equivalent to …

Edge-based semidefinite programming relaxation of sensor network localization with lower bound constraints

Pong, Ting - In: Computational Optimization and Applications 53 (2012) 1, pp. 23-44

In this paper, we strengthen the edge-based semidefinite programming relaxation (ESDP) recently proposed by Wang, Zheng, Boyd, and Ye (SIAM J. Optim. 19:655–673, <CitationRef CitationID="CR28">2008</CitationRef>) by adding lower bound constraints. We show that, when distances are exact, zero individual trace is necessary and sufficient...</citationref>
