Abstract:
A node localization method and device are disclosed. The method includes: determining a first set of radio signal measurement values that can be received by each known-location node of at least one known-location node, and determining a second set of radio signal measurement values that can be received by a to-be-localized node; determining, according to the radio signal measurement values included in the first set that respectively correspond to each known-location node and the radio signal measurement values included in the second set, a weighting coefficient corresponding to each known-location node ( 101 ); and determining location information of the to-be-localized node according to the weighting coefficient corresponding to each known-location node and location information of each known-location node ( 102 ).

Claim (Index 18):
A node localization device, comprising:\n a second determining module, configured to: for the i th  known-location node in M known-location nodes, determine a first set {p 1i , . . . , p Ni } of radio signal measurement values that is determined by the i th  known-location node according to received radio signals sent by N common nodes, and determine a second set {p 1 , . . . , p j , . . . , p N } of radio signal measurement values that is determined by a to-be-localized node according to received radio signals sent by the N common nodes, wherein i, M, and N are positive integers; a second processing module, configured to: for the i th  known-location node in the M known-location nodes, determine a set {\u0394p 1i , . . . , \u0394p Ni } of differences between the first set {p 1i , . . . p Ni } corresponding to the i th  known-location node and the second set {p 1 , . . . , p N }, wherein \u0394p 1i =p 1i \u2212p 1 , . . . , \u0394p Ni =p Ni \u2212p 1 ; and a second localization module, configured to determine, in preset localization space, location information of the to-be-localized node according to M determined difference sets, wherein the determined location information of the to-be-localized node meets a requirement of the following formula:\n P=f (( x,y,z )|{\u0394 p 11 , . . . \u0394p N1 }; . . . { . . . , \u0394p ki , . . . },{\u0394p 1M  . . . \u0394p NM }), \n wherein f( ) is a constructed joint probability density function, (x,y,z) is coordinate location information of the to-be-localized node, and P is a maximum value of the probability density function.
