Multi-source　multimedia　transmission　is　a　popular　architecture　in　wireless　mobile　peer-to-peer　(P2P)　networks.　Most　of　previous　work　on　wireless　mobile　P2P　networks　concentrates　on　the　protocols　and　network　structures,　and　consequently　ignores　the　multiple　senders　scheduling　problem.　In　this　paper,　we　present　a　distributed　algorithm　for　scheduling　the　multiple　senders　for　multi-source　transmission　in　wireless　mobile　P2P　networks,　which　can　maximize　the　data　rate　and　minimize　the　power　consumption.　Specifically,　we　formulate　the　wireless　mobile　P2P　network　as　a　multi-armed　bandit　system.　The　optimal　distributed　sender　scheduling　policy　can　be　found　according　to　the　Gittins　indices　of　the　senders.　Extensive　simulation　examples　illustrate　the　effectiveness　of　the　proposed　scheme.　It　is　shown　that　the　data　rate　and　power　consumption　in　the　proposed　scheme　can　be　improved　significantly　compared　to　existing　schemes.
