An efficient data offloading to cloud mechanism for smart healthcare sensors

The amalgamation of Mobile Cloud Computing (MCC) and Wireless Body Area Networks (WBANs) is the latest trend in the field of pervasive mobile health care monitoring systems. WBANs are low power sensor networks whose performance can be enhanced by integrating WBANs with cloud computing. Cloud Computing provides all the required resources (storage, memory, processing power) with minimum cost. An efficient health record management service is proposed in this article. It is based on real time data offloading to cloud from WBANs. The major goal of the proposed model is to effectively aggregate the data of patients in the various network segments in order to remove the communication overhead of headers and acknowledgements. A novel algorithm is proposed for data aggregation and offloading to the cloud. The proposed approach is energy efficient to deliver the data effectively to the cloud based health record management services. The performance of the proposed system is assessed on the basis of aggregation efficiency, total transmission time and end-to-end delay using matlab simulations. The experimental results show that the proposed model has added a minimum possible delay on the communication link and thus the data delivery has been efficient and quicker.
