Distributed patching for mobile wireless sensor networks

Research Abstract
Mobilewirelesssensornetworks(MWSNs),thecontinuousmovementofsensornodes,maycause completedisconnectionofthenetworkoratbestapartofit.Thedesignofsuchnetworksshould guaranteethatallsensornodesatalltimeshaveapathtothesinknode(s).Prolongingthelifetimesof the MWSNsisacrucialdesignissuebutshouldnotbeattheexpenseofotheressentialfunctionssuch as connectivity.Inthispaper,weproposeanenergyefficientdistributedframeworkforconnectivity maintenanceofMWSNs.Intheproposedframework,sensornodesoftheMWSNsscheduleandcontrol their radiofrequency(RF)modulesbasedondynamiccoordinatedreconstructionmechanism,some senornodesmaylosetheirconnectivitywiththenetworkduetomobility,depletionofenergyand/or incurredfaults.TwoprotocolsaredevelopedtopatchupthedisconnectionoftheMWSNs.Thefirst protocolreestablishesthenetworkconnectionconsumingfarlessenergythanstate-of-the-art alternatives.However,itiscapableofreestablishingtheconnectionwhennomorethan20%ofthe MWSN backbonenodesloseconnectionconcurrently.Thesecondprotocolextendsthislimittooperate when upto35%oftheMWSNbackbonenodesloseconnectionsimultaneously.
