The application scenarios of wireless sensor networks for health care systems are very complex, which require a new communication schemes that can dynami- cally ful¯ll these requirements and achieve e±cient data transmission. It brings a big challenge to routing, access control, data transmission, storage and processing. This paper presents a novel routing scheme named Virtual hy- percube routing (VHR), in which the routing selection and maintenance rules are de¯ned based on a logical hypercube structure. It can highlight good performance in data trans- fer rate and query e±ciency. Based on this structure, the routing for health care can be implemented e±ciently. We evaluate the performance of VHR using simulation under home and public area care scenarios. The results show that this scheme performs high data transfer rate, low latency and low overhead for communication under both static and dynamic scenarios.
