Introduction: Opportunitynetworkhasbecomeanincreasinglypopularformofonlinesocialnetworkingforindividualswhosharesimilarinterestsorgoals.However,thetransmissionofmessagesinsuchnetworkscanbechallengingduetothelargenumberofmembersandthecomplexityoftheirrelationships.Inordertoenableefficientmessagetransmission,weproposeacommunity-basedalgorithmthatgroupsmembersintocommunitiesandoptimizesmessageexchangewithineachcommunity. Community-basedmessagetransmissionalgorithm: Thealgorithmhastwomaincomponents:communitydetectionandmessageexchangeoptimization.Thecommunitydetectionmodulegroupsmembersintocommunitiesbasedontheirsimilarityintermsofinterests,activitylevels,andrelationships.Avarietyofcommunitydetectionmethodscanbeusedtoachievethisgoal,includingclusteringalgorithmsandcommunitydetectionalgorithms. Oncecommunitieshavebeenidentified,themessageexchangeoptimizationmoduleaimstooptimizetheexchangeofmessageswithineachcommunity.Thisisaccomplishedbyidentifyinginfluentialmemberswithinthecommunityandtargetingthemwithmessagestomaximizethelikelihoodthatthemessagewillbedisseminatedtoalargenumberofcommunitymembers.Toachievethis,thealgorithmtakesintoaccountthefollowingfactors: 1.Theactivitylevelofthemember:Higheractivitylevelsindicateagreaterlikelihoodthatthememberwillsharethemessagewithothers. 2.Thesocialinfluenceofthemember:Memberswithahighdegreeofsocialinfluencearemorelikelytospreadmessageswidely. 3.Thecurrentlevelofcommunicationwithinthecommunity:Ifcommunicationislow,morememberswillneedtobetargetedtoensurethatthemessageisdisseminatedwidely.
