Sensor　networks　are　widely　used　in　a　variety　of　commercial　and　military　applications　due　to　their　self-organization　characteristics　and　distributed　nature.　As　a　fundamental　requirement　for　providing　security　functionality　in　sensor　networks,　key　management　plays　a　central　role　in　authentication　and　encryption.　In　this　paper,　we　analyze　the　Adaptive　Key　Selection　(AKS)　scheme　and　the　corresponding　Adaptive　Key　Selection　algorithm　for　multiple　deployment　in　sensor　networks　in　terms　of　security,　connectivity　and　overhead.　We　show　through　simulation　that　the　AKS　scheme　can　greatly　improve　the　connectivity　and　security　of　the　existing　multiple　deployment　scheme　in　wireless　sensor　networks.　©　2007　IEEE.
