Internet of Things (IoT) is associate additional and additional normal technological trend. The operation of IoT wishe s a sturdy data- handling capability, where most of {data|of information} is device data. Limitations associated with live, delaysin data amendment, and/or the requirement to preserve the privacy {of data|of data|of information} could result among the device knowledge doubted. Thus, one key challenge is “How can we tend to confirm the privacy of knowledge collected from IoT devices, considerably unsure data, that square measure being outsourced to the cloud for analysis, storage and archival?”. Searchable encryption (SE) theme may be a promising technique that allows the wanting over encrypted (uncertain) data hold on offshore. throughout this Project Geo-distributed clouds offer associate intriguing platform to deploy on-line social network (OSN) services. To leverage the potential of clouds, a major concern of OSN suppliers is optimizing the money value spent in exploitation cloud resources whereas considering totally different important desires, additionally as providing satisfactory quality of service (QoS) and data accessibility to OSN users. throughout this paper, we tend to tend to review the matter of value improvement for the dynamic OSN on multiple geo-distributed clouds over consecutive time periods whereas meeting predefined QoS and data accessibility desires. we tend to tend to model the worth, the QoS, still as a result of the data accessibility of the OSN, formulate the matter, and elegance associate rule named cosplay. 10dency to|we tend to} offer enter depth experiments with a large-scale real-world Twitter trace over ten geo-distributed clouds all across the United States. Our results show that, whereas forever making sure the QoS and conjointly the data accessibility cosplay, can deflate much more one-time value than the progressive ways that, and it should conjointly significantly deflate the accumulative value once unceasingly evaluated over forty eight months, with OSN dynamics love real-world cases.
