Abstract：The existing WVSN（wireless video sensor network）target-barier construction technology does nottake accountof theful-viewcoverageandthesensorutilizationeficiencyisrelativelylow，sotheWVSNintrusiondetectionoftenfilsandthe workingdurationisnotlongenough.Tosolvethisproblem，analgorithm MFGTM（minimumfullviewgridtarget-bariermerging） isproposed toconstructandmergetheminimumful-viewgridtarget-barrersinWVSN.Firstly，theWVSNcoverageareais dividedintoqualsizegrids.Secondlyallfull-viewgridsaresearched，ndthenaminimumfull-viewgridarget-is constructedforachmonitoringobject.Finally，temultiplefullviewtarget-barriersaremerged.Thesimulationresultsshowthat theMFGTMalgorithmcanefectivelyconstructindependentfull-viewtarget-barrersformultiplemonitoringobjectsinWVSN， andcanmergethem eficiently.Incomparison with TBCalgorithm，thesuccessrateof target-barierconstructionof MFGTM algorithmisincreasedbyabout 23% ，and its average number of gridsand average number of nodes of target-barrier construction are decreased by about 20.2% and 10.8% ，respectively，and its merging efficiency of target-barriers isincreased byabout 20% Inaword，theproposedmethodefectivelyreduces thenetworkresourcelossduetobuildingthetarget-barrerandprolongs the life cycle of the network.
