Abstract
With the rapid growth of elderly population, u-healthcare service combined with advanced wireless networking technology is gaining popularity. The in-body and on-body nodes have very stringent requirements on transmit power and battery life. Furthermore, the wireless link in an in-body environment has a very high degree of path loss (e.g., 6.2 for deep tissue). Because of such worse settings for each communication node to deliver data packets to the other node, it is preferred to have a multi-hop network topology. This will ensure that each node can deliver data packets at a reduced expense of consuming a low level of transmit power, which is attractive to the live body of patients receiving the healthcare service due to the reduced level of radiation effect. We study an efficient method to deliver delay-intolerant data packets over multiple hops. As a solution we consider multiple description coding (MDC) and develop a mathematical formulation for packet-level scheduling of delay-intolerant MDC packets over multiple hops. The proposed method can be used as a simple guideline for applications to setting up a topology for a medical body area network (BAN) of each individual patient.
