In this chapter, we propose a priority based health data aggregation scheme (PHDA) with privacy preservation for cloud assisted WBANs to reduce the aggregation overheads and preserve user privacy. The health data are divided into different types, and each type of data is assigned a specific priority. When a user wants to upload his data, he can select different forwarding strategies according to his data’s priority. The intuition is that the data with higher priority can be forwarded in a smaller delay. Furthermore, the data with the same priority can be efficiently aggregated which significantly reduces the communication overheads.
