Virtual hypercube routing in wireless sensor networks for health care systems

Abstract

The application scenarios of wireless sensor networks for health care systems are very complex, which require a new communication scheme that can dynamically fulfill these requirements and achieve efficient 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 Hypercube Routing (VHR). In this paper, the routing selection and maintenance rules are defined based on a logical hypercube structure, which can highlight good performance in data achieve rate and query efficiency. Based on this structure, the routing for health care can be implemented efficiently. We evaluate the performance of VHR using simulation under the home care scenario and public area care scenario. The results show that this scheme performs high achieve rate, low latency and low overhead for communication under both static and dynamic scenarios. ©2009 IEEE.
