Accompanying　dramatic　advances　in　wireless　Mesh　networking,　the　demand　for　advanced　mechanisms　to　employ　wireless　Mesh　networks　in　public　safety　continues　to　grow.　However,　this　special　field　communication　brings　new　security　challenges.　In　this　paper,　we　propose　a　behavioral　model　NODE　EYE　for　secure　group　communication　in　wireless　Mesh　networks.　We　contend　that　our　model　facilitates　reasoning　about　protocols　designed　for　public　safety　by　integrating　the　behavioral　trust　and　cryptographic　aspects　of　group　communication　in　the　special　field.　We　illustrate　our　concept　by　introducing　group　key　agreement　and　distribution　protocols　to　support　special　communication　cases　associated　with　the　public　safety.　©　2010　ACM.
