Levy walk evolution for global optimization
(ACM, 2008-07)A novel evolutionary global optimization approach based on adaptive covariance estimation is proposed. The proposed method samples from a multivariate Levy Skew Alpha-Stable distribution with the estimated covariance matrix ... -
Positioning algorithms for cooperative networks in the presence of an unknown turn-around time
(IEEE, 2011)This paper addresses the problem of single node positioning in cooperative network using hybrid two-way time-of-arrival and time-difference-of-arrival where, the turn-around time at the target node is unknown. Considering ... -
Range based sensor node localization in the presence of unknown clock skews
(IEEE, 2013)We deal with the positioning problem based on two-way time-of-arrival (TW-TOA) measurements in asynchronous wireless sensor networks. The optimal estimator for this problem poses a difficult global optimization problem. ...
