The　development　of　distributed　smart　homes　is　accelerating　with　the　approach　of　the　Pervasive　Computing　era.　Heterogeneous　devices　and　network　is　a　significant　feature　in　these　smart　homes.　However,　the　realization　of　a　real　environment　is　difficult　and　always　takes　a　long　time.　It　is　unrealistic　to　verify　the　availability　of　the　entire　system　and　make　sure　that　all　devices　and　applications　can　work　together　after　finishing　the　development.　In　this　paper　we　present　a　configurable　context-aware　simulator　for　distributed　smart　homes.　XML　configuration　files　are　used　to　save　information　for　constructing　the　home　environment,　virtual　devices　and　services,　simulating　context　information　and　testing　the　OSGi　event　interaction　between　devices.　This　makes　the　simulator　can　work　under　different　smart　home　environment　which　based　on　the　OSGi　framework　without　modifying　any　code.　And　the　simulated　virtual　devices　can　work　with　real　devices　with　the　help　of　the　simulator.　It　is　easier　to　provide　a　complete　simulation　environment　for　a　device　to　test　and　verify　during　the　development　process.　©　2011　IEEE.
