As　an　emerging　portable　service　platform,　OSGi　is　now　taking　a　more　and　more　important　role　in　Ubiquitous　Computing　environment.　As　a　module　management　framework,　OSGi　provides　the　functions　of　dynamic　loading　and　unloading　software　modules　at　runtime.　But　its　use　is　limited　because　it　is　centralized　and　single　programming　language　supported.　In　this　paper　we　present　LIR-OSGi,　an　extended　framework　of　OSGi,　which　is　designed　to　add　the　distribution　and　programming　language　independence　to　OSGi.　Meanwhile　it　is　easy　to　use　for　developers　because　of　the　transparence　of　service　invocation　and　automation　of　distribution.　Not　like　OSGi　which　can　be　applied　only　on　the　Java　platform,　LIR-OSGi　makes　programs　which　may　be　written　in　different　programming　languages　be　able　to　call　each　other　transparently　so　that　it　can　be　applied　in　many　different　platforms　such　as　DotNet　Framework　and　so　on.　This　brings　much　convenience　to　the　program　development　in　a　distributed　and　heterogeneous　environment.　©　2011　IEEE.
