Wormhole　attacks,　as　a　devastating　type　of　threats　in　wireless　mesh　networks,　have　received　much　attention　in　recent　years.　This　paper　proposes　a　type　of　wormhole　attack　model　and　its　corresponding　detection　scheme.　In　this　scheme,　the　combination　of　a　number　of　techniques,　such　as　distributed　voting,　watch-nodes-based　detection　and　identity-based　cryptosystem　are　used.　The　simulation　results　and　qualitative　analysis　demonstrate　the　performance　and　cost　of　the　proposed　scheme　are　more　advantageous　over　the　some　of　the　previous　schemes.
